As highly-tuned combustion engines crackled loudly into life, electric-driven racers whirred quietly by. You could see and hear the innovation. But it was not just the pits that were buzzing with activity, so was the Loctite® tent – with student mechanics looking for last-minute repairs and advice, like the Politechnica Wroclawska team who turned up in a big hurry with a leaking fuel line. “We cannot risk damaging the parts by using any heat. The Loctite® engineers advised using Hysol® 9492, an epoxy adhesive. It is quick and safe. Just what we are looking for,” explained team mechanic Mateus Roszkowski. Formula Student is open to universities and technical colleges around the world, and Hockenheimring is one of the highlights of the season. The rules are simple: the brief is to design and build a compact, high-performance prototype aimed at the amateur racer market. It must be low on cost, low on maintenance but high on performance, design and quality. Teams are assessed over a range of disciplines designed to measure their engineering and business skills, with the winner having the best overall performance. In 2010, the DUT Racing Team from the TU Delft took the honours with their 450cc single-cylinder-driven masterpiece. Formula Student has proved so popular that the online subscription closed within seconds of going live, with 98 teams from all over the world registering – and 78 made it to the Hockenheimring! at work | Issue 5 Highlight Fast, silent and electric The race into the future got off to a flying start with the debut of Formula Student Electric at the Hockenheimring in 2010, with the GreenTeam Uni Stuttgart winning the overall event. The student engineers have no doubts that their championship will play a vital role in the development of a cleaner mode of transport for tomorrow. niversity of Applied Sciences Zwickau’s FSE team won U the award – the second year running for Zwickau. “One of our applications for the award benefited from some of Henkel’s oldest adhesive know-how. We used Loctite® 620 for the shaft-hub connection on our innovative electric motor,” says Sebastian Fethke. “It fitted our team slogan ‘Innovation meets tradition’ perfectly.” But don’t make the mistake of thinking that ‘clean’ means ‘slow’. A full-blooded Japanese racing bike engine might sound faster than a quiet electric motor, but is it? Thanks to a better torque curve than a combustion engine, acceleration from an electric motor can be even quicker, despite cars weighing 30–50kg more because of the batteries. So how fast is that? About 3.5 seconds from 0 to 100km/h ... and virtually silent! Investing in tomorrow with Formula Student Henkel’s investment in Formula Student is already promising rich returns. Rudolf Neumayer, head of General Industry European technical service, explains: “Industry engineers are very specialised and must follow strict guidelines, but Formula Student engineers have a much wider overview and are far freer. They find creative new ways of using adhesives. The next generation recognises the considerable benefits and we expect that to lead to greater demand for our products.” A paradigm change Many car companies still rely on traditional bonding methods to produce their cars, but for the engineers of tomorrow, the future definitely belongs to adhesives. Formula Student engineers are already using these new possibilities to design the demanded lightweight and downsized automobile constructions. “Henkel embodies the spirit of Formula Student Germany, mixing theory and practice,” says Tim Hannig, the Formula Student Germany chairman. “With the student training programme, designers learn how to integrate adhesives into the construction of the car. And with the Loctite® tent, the mechanics can get advice and practical help – a really vital first-aid service for our competitors.” Innovation meets tradition The Henkel Award for “Best use of adhesives” aims to encourage students to use Loctite® products. The at work | Issue 5 | 5 6 | Highlight The stuff of c hampions The Dakar Rally is famous for pushing man and machine to the limit, but even by its own standards, the 2011 Argentina–Chile rally was an especially arduous challenge. There were plenty of flying stones and debris around to smash up b odywork, transmissions and cooling systems – in a split second, a race leader could be relegated to s pectator. No matter how good man and machine are, to win the Dakar you need a highly skilled s upport team to patch up the damage quickly and safely. Loctite® to the rescue After seven years of service, the Loctite® team of six engineers, or “Charlies”, are now part of the Dakar – and like the competitors, they are made of tough stuff. Take chief Charlie Jean Gaborit from France. “I love the Dakar – it is a real team effort. No one can win without the support of their mechanics – or us! From major repairs to fixing boots, Loctite® has the products and the know-how to get c ompetitors back on track.” Not just heat and dust … at work | Issue 5 Highlight But what happens when the mechanics are not there? Even then, all is not necessarily lost. Marc Coma was out alone in the Chilean wilderness when his bike suddenly fishtailed and crashed, sustaining a serious radiator leak. “I thought my race was over,” recounts Coma, the ace rider from Barcelona. “But I had Loctite® 3463 with me – it is very easy to use and dries fast, so I could keep my overall lead. The only hard part was finding the leak!” It is Loctite’s drive to innovate that works such wonders. For example, Loctite® 3090 – the only instant adhesive with gap-filling up to 5mm – made its debut on the 2010 Dakar. And it was thanks to this innovation that the lights did not go out on Orlando Terranova’s 2011 rally. After a bad knock, the Loctite®-sponsored BMW X3 suffered damage to the plastic mounting of its headlight. “They had no replacement, so we used Loctite® 3090 to repair the damage. After ten minutes, Terranova was back on the road,” says Jean Gaborit proudly. While the Dakar teams get a lot out of Loctite®, it works both ways. Jean Gaborit expands: “The Dakar gives us the opportunity to know our products even better. For example, we used Loctite® 3463 to fix a broken brake caliper housing that reaches very high temperatures. Although the recommended continuous service temperature is 120°C, it held perfectly until the end of the race, despite all the Coma celebrates his hard-fought third Dakar title Fixing a broken headlight mount with Loctite® 3090 v ibration. That is very useful to know. The Dakar, after all, is about discovering your limits – for manufacturers as well as competitors,” he adds with a wink. Reliability at work Loctite® 3463 •Easy to use: steelfilled k neadable stick •Adheres to damp surfaces and cures even underwater. Sets in ten minutes Loctite® 3090 •Fast curing two- component cyanoacrylate •Transparent gel •Dries in 90–150 seconds •Fills gaps of up to 5mm •Ideal for bonding a large variety of substrates Marc Coma blasting through the desert on his Henkelsponsored factory KTM 450 RR to win the 2011 Dakar – his third: “I had to fight the whole way against really tough competition and gruelling conditions. The scariest moment was the crash on the fifth stage that punched a hole in the radiator. If I had not had my Loctite® repair kit with me, my race would have been over – but with Loctite® 3463, I stopped the leak and finished that stage third!” at work | Issue 5 | 7 8 | Reliability Report 9 A beast, but beautiful It is getting dark, it is already -16°C, it is beginning to snow and you are on an icy 30 degree-steep slope. Not exactly perfect d riving conditions, but the sleek metallic s ilver Prinoth Beast does not even blink. No wonder – this monster piste groomer is the most p owerful in the world! It is also the most efficient, with over 40% more grooming area, which is good news for the environment. The heart of the Beast is the 12.5 litre Caterpillar C13 Acert turbo diesel engine, which delivers a huge 527hp at just 1,800rpm and conforms to Euromot III A guidelines. Four 180cc Bosch Rexroth hydrostatic pumps transmit the power to the tracks and drive the tillers and blades. But the Beast is not just about performance, it is also about looks and comfort. Styled inside and out by the world-famous Pininfarina design studio, it is as easy on the eye as it is on the body. at work | Issue 5 Reliability Report 9 Massive 7.1m wide power tiller Side wings for perfect pistes The hydraulic valve unit Loctite® 638 and Loctite® 572 seal hydraulics at work | Issue 5 | 9 10 | Reliability Report 9 Night and day Overall track area is 45% more than that of its closest rival, which means the pistes get prepared faster. Loctite® 638 retains the ice studs and aluminium track blades. Reliability at work Customer: Prinoth AG / SpA, Sterzing / Vipiteno, Italy Tasks: Threadlocking Retaining Sealing Products: Loctite® 243 Loctite® 572 Loctite® 638 Piste grooming is best done at night when skiers and boarders are in the bars or tucked up in bed. But out there, it is not quite so cosy, with temperatures often 30 degrees or more below freezing and slopes that can be over 45 degrees steep. Prinoth relies on Loctite® products extensively in the Beast to secure components and seal hydraulics, no matter how low the mercury gets. Is this for real? Skiers staring downhill at the start of a steep black slope know what to expect – that thrilling acceleration, that rush of cold air, that hissing snow. In the Beast you have the same view, but the similarity ends there. You sit snugly in a comfortable rally-style seat, prevented from tipping forward by your harness, at a comfortable 20°C and with some nice lounge sounds from Kruder & Dorfmeister on the hi-fi. Then, best of all, you suddenly spin round and go back up that same steep slope, shifting several tons of snow at the same time! And despite the crazy angles, you feel completely stable and in control. The machine with its 527hp and 2,216Nm of torque is as powerful as a ship. There is no dramatic acceleration or braking, just the feeling that nothing can stop you. Big benefits The rationale behind the Beast is that thanks to its power and grooming performance, it can prepare pistes far more efficiently than smaller machines – saving up to 40% on time and costs. Prinoth belongs to LEITNER Technologies, who know the ski infrastructure business inside out. The at work | Issue 5 Italian conglomerate, based in Sterzing, is a world leader in ski lifts and installations and is also a major force in urban cableways and wind turbines. Keeping the driver fresh and relaxed is also important – tiredness means more breaks and increases the chance of mistakes. That is why Prinoth worked with Pininfarina to design a cockpit that is simple and intuitive to use. The workmanship is naturally to the highest standards – and fully customised so that the Beast fits the exact individual specifications of drivers and resort owners. Safety and control Piste grooming is not without its hazards, and resorts use their piste groomers not only to prepare the slopes but also to prevent any dangerous build-up of snow. Control is the key to safe operation and the Beast uses CANbus technology that integrates operational systems with driving conditions to deliver real-time data for on-board diagnostics, so that drivers know exactly what is going on around them. And for the worst-case scenario, the cockpit is protected by a safety cage. Synonymous with reliability Prinoth machines are known for their quality and reliability, which is why only the very best partners, such as Pininfarina and Caterpillar, are chosen. But as the saying goes, you are only as strong as your weakest link, so to make sure those links stay as strong as possible, Prinoth’s assembly plant in Sterzing works with Loctite® products – from sealants and Reliability Report 9 Uncompromising efficiency Prinoth’s works in Sterzing / Vipiteno, Italy, where the Beast and other machines take their final shape. Components and parts shipped from Canada, the US or local plants are quickly but carefully hand assembled by the 150 employees. “We need to work fast, but without any compromise on safety or reliability. That is why we use Loctite® products, which are easy to work with,” says Peter Wieser, head of assembly. “Our customers expect 100% reliability from us – and we know we can rely 100% on Loctite®.” Peter Wieser Head of assembly general adhesives, to threadlockers and retainers. “There is no production line here as such because the machines are customised and not mass-produced,” explains Peter Wieser, head of assembly. “That means we must be flexible. Luckily for us, Loctite® has the right product for all our requirements – clearly labelled and easy to use too, which is vital when things get busy.” Hydraulics are crucial to the Beast, driving the tracks, blades and tillers. Sealants must be able to cope with pressures of up to 500bar and temperatures way below zero. Thomas Strickner, assembly mechanic, uses Loctite® 638 to seal hoses and joints. “You can use it safely with a lot of different materials and it is very strong. Because of the extreme conditions, any mechanical failure is potentially very serious – which is why we must always deliver the highest quality of workmanship.” Thomas Strickner Assembly mechanic Track-drive wheel secured with M20 bolts tightened to 365Nm and threadlocked with Loctite® 243. at work | Issue 5 | 11 12 | RD&E Insights Making the impossible possible Modern alchemists at work What sets Henkel and its brand Loctite ® apart from the competition is their passion for research and development. Like the ancient alchemists on their mission to find the way to turn base metals into gold, Loctite’s engineers and scientists are looking for a way to bond the unbondable – but unlike the alchemists, Loctite ® has succeeded in working its magic. Chris Hollands Technology Manager Europe at work | Issue 5 Today’s world is literally held together by structural bonding adhesives that are increasingly replacing traditional fastening methods like riveting or welding. Whether it’s the medical industry or renewable energy, Loctite® has a reputation for coming up with the answers. Chris Hollands, technology manager for structural adhesives in Europe, explains: “Most adhesive manufacturers offer adhesives, but what sets us apart is that we offer solutions for almost every application – we make the impossible possible across the whole 360° of industrial assembly applications. Within structural bonding we have five core technologies that we are continuously developing – epoxies, acrylics, silicones, polyurethanes and silane-modified polymers, which together enable us to find the right solutions for our customers’ needs. Loctite® 3038 and Loctite® V5004, new additions to our range, are good examples of that.” Loctite® 3038 – never say never Some things just do not mix well – like polyolefins (polypropylene and polyethylene) and steel – which was causing the automotive industry serious problems, particularly when trying to fix headlights, front and rear ends, dashboards and exterior trims. There were few very good products available – and none that could handle this challenge without a lot of time-consuming surface pretreatment with the likes of plasma, flame or primers. That was until a leading German car manufacturer approached Loctite®. “Our product development team in Dublin got the brief to come up with an adhesive that would bond polypropylene mouldings to painted steel without pretreatment in the very challenging under-bonnet environment,” explains RD&E Insights Peter Wrobel, senior development scientist for Europe. “After 18 months of development and testing, we came up with Loctite® 3038, a high-performance but easy-to-use two-component acrylic. It has opened up a whole new range of opportunities for engineers when designing bonded assemblies.” Originally developed for the car industry, Loctite® 3038 is now being used in areas like marine engineering, filter manufacture and construction of point of sale displays. Brett Jenkinson, senior sales engineer, UK, who works closely with marine and water sports customers, explains its appeal: “It’s perfect not only for use in the construction phase, but also for repairs. It’s quick, user-friendly and ffers the same performance whether substrates are o treated or untreated.” Loctite® V5004 – invisible power “Loctite® V5004 is a transparent, high-strength structural adhesive that can bond a wide range of substrates, which is pretty much unique,” says Hollands. “Fast curing, it’s an important addition to our range designed to provide 360° solutions.” www.360bonding.com/uk Companies that need quality adhesives that are totally transparent have been impressed by Loctite® V5004’s performance, reports John Dubber, Loctite® technical customer service, UK. “One of our customers manufactures cosmetic display units that require total transparency. They use the adhesive in the construction phase and value the fast setting time and ease of use.” With these excellent qualities, Loctite® V5004 is also perfect for the signage industry. “It’s important to have an adhesive that can be simply applied and that combines high performance with quick curing times,” says Dubber. The transport industry in France has also taken to Loctite® V5004, because it is shock and vibration resistant – which makes it perfect for such applications as securing lighting fixtures in trains. From Plexiglas and acrylics to aluminium, Loctite® V5004 ensures transparent, high-strength bonding. “Our customers come to us for innovation,” says Hollands proudly. “No matter what they need to bond, no matter what the conditions are, if it’s technically feasible, we’ll find a way. Now if you’ll excuse me, it’s back to the lab,” he smiles apologetically. “We have a couple more surprises up our sleeve.” Reliability at work Loctite® 3038 Loctite® V5004 Features & Benefits Features & Benefits •Very good adhesion to polyolefin s ubstrates (PP, PE) •Clear bond line after curing •Gap filling up to 2mm •Good adhesion to metals and plastics •Thixotropic; application on vertical surfaces possible •Shock and vibration resistant •Fast curing, fixture time of three minutes •Solvent-free, low odour •Good impact resistance •Non flammable Please visit our 360º Bonding website where you will find many more innovations, product details and an on-line application guide www.360bonding.com/uk at work | Issue 5 | 13 14 | Trend Report In the circle of life at work | Issue 5 Trend Report Bioplastics – learning from nature Plastic – a success story that began in 1910 with the industrial production of Bakelite. Today, 100 years later, a world without plastics would be a world w ithout computers, telephones, cars, aeroplanes, medical care, mass production of food, high-quality insulation products and much more. Nevertheless, plastic has a serious p roblem: it is virtually immortal. But solutions are in sight. Today, the annual production of plastic products is 285 million tonnes a year, including 14 million tonnes of polystyrene and 40 million tonnes of PET. As an illustration: this amount corresponds to the volume of some 100 Great Pyramids of Giza made of non-foamed plastic, plus 250 styrofoam pyramids and 12 pyramids made of PET – mainly bottles and packages – every year. A brief history of plastic In the mid-19th century billiards had become the new national pastime of the Wild West. But billiard balls were made of ivory and therefore expensive. Inspired by a $10,000 prize, in 1866 John Wesley Hyatt developed celluloid, made of cellulose nitrate (guncotton) and camphor, to replace ivory. But the production of celluloid was an extensive process, the necessary raw materials were expensive and sometimes a billiard ball caught fire because of remaining quantities of nitric acid. opened up a wide variety of technical features for plastics and a previously unknown variety of colours, shapes and practical uses. In the record-breaking year of 1976, plastic was for the first time the most widely used raw material in the world. However, at 50 million tonnes, the volume produced in 1976 was, compared to the current volume of 285 million tonnes, relatively modest. Plastic products now have virtually all the features and requirements asked for by consumers, technicians, and the economy. And in most cases, with very competitive prices compared to other raw materials. But the growth is not without consequences: 1. To produce these quantities of plastic, more than 4% of the world’s crude oil production is used by the plastics industry. As regards increasing prices of crude oil this is of lesser importance for expensive plastics, but it may become an economic challenge in the low-price segment. But the almost unlimited pliable plastic that could be produced in any colour quickly conquered consumers’ hearts: Jewellery, bowls, toys and artificial teeth were made of celluloid, long before it was used in photography and film. 2. With the falling prices of plastics the field of usage increased, to the point where it has become a daily disposable product that is produced to be used for just a few minutes, before it is discarded forever. From cotton to coal and oil Celluloid was of very limited use industrially due to its flammability, as the ascending importance of the electricity industry was hardly compatible with flammable cellulose. 3. The accumulated waste is an increasing burden on the economy and the environment. The particular advantage of modern plastics, their durability, turns into a problem for generations as soon as plastic becomes waste. In 1910 Leo H. Baekeland solved the problem by inventing a non-combustible material made of the mass waste from the coal industry (phenol), thus providing the electrical industry with a burst of development: instead of expensive metal or wood cases, and glass or ceramic insulators, it was now possible to produce machine parts, telephones, radios and vacuum cleaners quickly and relatively cheaply. The dark side of the boom In 1997 Charles Moore, member of the Algalita Marine Research Foundation, discovered a floating plastic field that extended far beyond the horizon when he sailed in a regatta between California and Hawaii. More detailed investigations revealed that a sea of plastic waste has accumulated in recent years in the Pacific Ocean. This waste field has now grown to a volume of about 100 million tonnes, floating slowly in a huge circle between California and Japan. The centre of this so-called Great Pacific Garbage Patch in-between the West Coast of the United States and Japan covers an area of 1.8 million square kilometres and is as big as Alaska or Libya, or five times as large as Germany or Japan. But Bakelite was by nature always dark in colour, hard and brittle, and therefore suitable only for a limited area of applications. The turnaround came after 1930 with petroleum-based plastics: polyethylene, PVC, nylon, rayon and polypropylene at work | Issue 5 | 15 16 | Trend Report But the Pacific Plastic Vortex is not the only one to be found. A total of five large plastic vortexes are known worldwide: two in the Pacific, two in the Atlantic and one in the Indian Ocean. The biggest pollution density was discovered by researchers in the North Pacific, where up to 320,000 pieces of plastic per square kilometre are swimming in the ocean. The UN Environment Programme estimated in 2006 that up to 90% of the floating waste in the oceans is plastics. Global production of plastic material (%) Source: WG Market Research and Statistics Japan Asia (without Japan) Internationally, only a few countries have a comprehensive recycling system for plastic waste, such as Switzerland, where 98% of plastic waste is recycled or used for energy production. Globally, the recycling rate of plastics is only 5%. 29 Rest of the world 4 Africa, Middle East 6 The bright side of life In times of increasing scarcity of raw materials and steady increase in oil prices, research focuses on tackling the problem at the root: the fact that most plastics are non-biodegradable. In terms of product usage, this product attribute is in most cases neither necessary nor requested. 6 5 Eastern Europe 8 Germany Western Europe (without Germany) The solution was found in biodegradable polymers. They have similar properties to their petroleum-made cousins, but – depending on the type – can be composted within a few weeks or months. Numerous examples of their usage indicate that the quality of these bioplastics is quite competitive: 26 16 North America • In 2008 Airbus launched a research programme to substitute fibreglass fabrics with natural fibres such as hemp, flax and kenaf as a composite material for aircraft interiors. The fibres can be used in items such as the side walls, the roof covering, seats, insulation and in other areas. • Ford already uses over 290 components made from renewable raw materials in its European car models, thus processing 27,000 tonnes of bioplastics per year. • The BMW 7 Series uses 24kg of renewable resources per car, including 13kg of natural fibres in the door panels and sound insulation. • In 2006 Mazda introduced an environmentally friendly bioplastic for car interiors, which consists of 88% cereals and only 12% petroleum substances. • The bioplastics company Gehrplastics, which won an award in 2008, manufactures semi-finished products made from biopolymers for industrial use that are similar to products made from petroleum in their physical and chemical properties. Recycling of plastic material within the EU Source: www.plasticeurope.org Switzerland Denmark Germany Sweden Belgium Austria Netherlands Norway Luxembourg France Italy Slovakia Hungary Finland Czech Republic Spain Portugal Estonia United Kingdom Slovenia Ireland Latvia Romania Poland Bulgaria Malta Cyprus Lithuania Greece But not every kind of plastic made from biological raw materials is necessarily naturally degradable. In some cases this is not requested and would be dangerous – no one would appreciate slowly decaying components in cars or aeroplanes. But now bioplastics provide the ability to design a material that can, depending on its use, be permanently preserved or decay a short time after usage. Recycling rate in % 0 10 20 30 Recycling rate Thermal recycling at work | Issue 5 Regarding the processing of biopolymers, there are, compared to petroleum-based plastics or metals, certain differences to consider. Since the chemical properties of bioplastics are close to those of products made from petrol, modern processing and bonding techniques can be used to produce competitive, market-accepted and environmentally compatible products. 40 50 60 70 80 90 100 The future The production and use of bioplastics has already taken root where particular material properties, recyclability and environmental market requirements exist. Trend Report Reliability at work Facts: 245 million tonnes: Plastic production per year worldwide (without PET) Plastic is essential for aircraft manufacturers, … … modern cars … In the future, typical applications of petroleum-based plastics can be covered by bioplastics: As soon as the economies of scale take effect in the bioplastics industry due to increasing capacities, their use will be as common as using petroleum-based plastics today. Mechanical engineering In mechanical engineering, the vibration-damping properties of biogenic material reduce material stress and thereby help to extend maintenance intervals and optimise usage times. Cotton-based insulation materials, often themselves already made from recycled materials, also help reduce the acoustic load. Aviation Airbus and Boeing are using renewable resources for the development of their new generation of aircraft. In the cabin interior they are used for trim and seats. And Boeing uses kenaf-based carbon to produce parts of the lightweight wings of the upcoming Dreamliner. The mountains of plastic waste in landfills and oceans will stop growing and will eventually disappear. 40 million tonnes: Annual production of PET plastic (for bottles, cans, cones) per year 50%: Proportion of p lastic that is recycled in Europe 5%: Proportion of p lastic that is recycled worldwide 1%: Percentage of biodegradable plastics 450 years: “half-life” of a plastic bottle 5000 years: “half-life” styrofoam Wind power The rotor blades of wind power plants, currently mainly produced from GRP, offer a wide range of applications for the use of fibre-reinforced bioplastics. They facilitate the expensive disposal of the rotor blades and improve the overall environmental performance of the systems. Yet only about 1% of the plastics manufactured worldwide are b iodegradable. But this will change very soon with the increasing price of crude oil, the growing cost of waste disposal and stricter legal guidelines for the use of plastics in consumer goods. The global capacity for production of bioplastics is already increasing exponentially. With an average growth of 8 to 10% per year, bioplastics may cover up to 30% of world plastic demand in the medium term. … and the wind power industry. at work | Issue 5 | 17 18 | Reliability Report 10 Sleek, aerodynamic design at work | Issue 5 Reliability Report 10 Silver Star Love it or hate it, you will never forget it ... 1,620m long and 73m high for a three-minute adrenaline-filled ride! If you have ever wondered what the acceleration and G-force of a Formula One car feels like, then you should take a trip on Europa-Park’s h ypercoaster, the Silver Star. But it is not just the performance that is hair-raising – so are the heights. And it is all done by gravity ... 130km/h and over four G’s! Hypercoasters are steel constructions that are super-tuned for maximum speed and airtime – that is negative G for that flying feeling. The enormous forces call for the highest standards of engineering and maintenance. The Silver Star meets all Germany’s stringent TÜV safety requirements. Guide wheel assembly The crucial safety bar The beginning: smiles and relief all round Much, much bigger than any picture can show at work | Issue 5 | 19 20 | Reliability Report 10 Reliability at work Customer: Europa-Park, Germany Task: Threadlocking safety bar units. Threadlocking guide wheels. Retaining guide wheel ball-bearing cages. Products: Loctite® 243 Loctite® 638 Loctite® 7063 at work | Issue 5 Do not hang on tight! The Silver Star feels reassuringly solid. The seats could be out of the latest rally car, but it is the safety bar that impresses the most. It is a heavy steel construction with a futuristic handlebar unit clad in black padding that fits snugly and shuts with a satisfying clunk to hold you firmly in position. Extreme performance, extreme thrills The ride begins with a slow, nerve-wracking climb that presses you deep into your seat. As the train reaches its 73m peak, it almost stops – but then shrieks of terror and delight break out as the Silver Star suddenly goes into free fall, accelerating to 130km/h, thundering through a series of turns and drops designed for maximum airtime. The more timid hang on to their handlebars, while the daredevils hold up their arms to make the most of the negative G – secured by their safety bar, of course. Just as you begin to think it must be all over, the train suddenly rockets into a horseshoe with a 120° bend for the thrilling grand finale. Then the screams of exhilaration become cries of joy and relief as the riders feel the train decelerate and realise they are still in one piece. How do they do it? Truly mind-blowing performance equalling the acceleration and G-force of a Grand Prix car – but without an engine! How do they make sure it runs smoothly and safely? High tech and traditional values Rollercoasters have come a long way since the old Russian mountain days – they were originally ice runs on wooden supports, up to 25m high, dating back to the fifteenth century from St Petersburg. Now the latest – like the Silver Star – are computer-controlled. The speed and passenger load are constantly calculated to apply just the right amount of magnetic braking, but just like the Russian mountain times, vibrations and safety are still issues. To ensure that the safety bars do their job, they must be vibration-proof. Hans Volz, the chief engineer in charge of Silver Star maintenance, relies on Loctite® 243: “We check all 108 bars every day and annually strip the units down completely for detailed inspection. For reassembling them we use it to threadlock the bolts that connect the ratchet parts to the main bar. Because Loctite® 243 is medium strength, it is strong enough to withstand the loads and vibrations, but can be disassembled for maintenance. It is perfect for us.” Keeping the wheels rolling The guide wheels are crucial to providing a fast but safe ride and keep the train locked to the track from above, below and from the side. Like the safety bars, the wheel units are checked daily – and stripped down, examined and reassembled every year. The steel ball-bearing cages must be completely removed from the aluminium wheels for a full inspection, and when there are 120 wheels to check altogether, efficiency is important. Reliability Report 10 Cleaning with Loctite® 7063 Safety bar and ratchet mount | 21 Applying Loctite® 243 Ready for assembly Retaining ball-bearing casing with Loctite® 638 Fastening wheels to train, the bolts threadlocked with Loctite® 243 Chief mechanic Volz has a useful trick: “Because aluminium expands faster than steel, we warm up the wheels to 70°C, which allows us to simply push out the steel ball-bearing cage. We then clean all surfaces with Loctite® 7063. We use Loctite® 638 for fixing the cage – it’s a high-strength retainer, ideal for dealing with cylindrical metal parts.” Loctite® 243 is used to threadlock the bolts that secure the ball-bearing cage casings and also to threadlock the bolts that fasten the wheels to the train. “Loctite® 243 saves us a lot of time, but doesn’t compromise reliability in any way,” adds Achim Stoss, the engineer responsible, amongst other things, for Silver Star maintenance. “It holds tight for as long as we need, but we can still dismantle parts with hand tools.” Despite being Germany’s largest theme park and the biggest seasonal park in the world, Europa-Park is still a family business. “The Mack family have been in the rollercoaster business since the 1920s. The traditional family values still continue – you see that in the pride people take in their work here,” says Alfred Kaltenbach, Loctite’s sales area manager. A relationship built on trust Europa-Park has just celebrated its 35th birthday, although it does not show its age, looking as if it was just finished yesterday. Even the immaculate Silver Star is over eight years old. Maintenance and testing are crucial to maintaining the highest safety standards and reducing repair bills. “Responsibility is part of our job, but so is efficiency. That’s something the Loctite® team understand.” Hans Volz Silver Star chief mechanic “I have been working closely with Europa-Park for 18 years now. Rather than having a supplier-customer relationship, we have a partnership.
