When power meets precision
HKS rotary actuators

HKS rotary actuators have it all
1
Outwardly hydraulic rotary actuators do not seem all that
impressive. You just cannot see what is inside them. No one
would suspect that our strongest model could easily move 20
VW Golfs from one side to another.
Our hydraulic rotary actuators are compact units which can
generate very high torque in very little space with hydraulic
pressure. And because they are extremely precise and easy to
control, in spite of their enormous strength, HKS rotary
actuators have conquered nearly every field in which limited
rotary movement with high torque is required.
Precision at the limits of the possible
Dirt, dust, moisture...? So what!
The linear movement of the hydraulic piston is
converted into rotary movement by means of
multiple helical gears. This is the same principle
a drill uses.
Whoever thinks that such high precision is sensitive, is in for a pleasant surprise: exactly the opposite is true for the HKS rotary actuators. With
working pressures of up to 350 bar, they require
a strong, well-sealed housing. This also provides
excellent protection to the interior. Our rotary
actuators are therefore completely immune to
dust, dirt, and moisture. It is therefore no wonder that one can rely completely on them even
under the most difficult conditions, whether deep
underground in mines or 2,300 meters under sea
level. HKS rotary actuators again proved their
reliability in the raising operations on the Russian atomic submarine Kursk.
The helical gears thus convert hydraulic pressure
into very high torque levels. For rotary-lift
combinations a linear movement is added to the
rotary one.

Unobtrusive – but strong and
reliable: HKS rotary actuators
for mobile applications.
The principle is quite simple, however a great deal
of precision is necessary to give our rotary
actuators their function and well-known
reliability. This precision lies at the limits of what

is currently possible. We are therefore rather
proud that we are able to reduce the tolerance
in the angle of rotation in our actuators to less
than 10 angular minutes. More important for
practical use, however, is the fact that all the
modular units in our rotary actuators can be
exchanged within minutes, if necessary.
Our rotary actuators have also acquired an excellent reputation where the highest levels of
cleanliness and hygiene are necessary. For example, their reliability is highly valued in the pharmaceutical industry and in food production because of their cleanliness in operation.

Attachments are positioned, lifted, and lowered
using rotary actuators, for
example, the soil compactor here.
Construction machinery is one of the traditional
uses for hydraulic rotary actuators. In pile drivers
and pulling machines, for example, leaders
weighing tons must be brought precisely into
position down to the centimeter. The vibrating
impacts, which drive sheet piles up to 22 m long
into the ground, do not bother the HKS rotary
actuator in the least.

Our hydraulic actuators for implements for community services make workers’ lives easier.
The actuators ensure that the equipment is both
mobile and can be positioned exactly. This makes
it possible for machines to do work that previ-
ously had to be done by hand. Thanks to their
robustness and compactness, HKS rotary actuators can be used in especially long lasting and
ergonomic designs.

More safety in wind and weather

26 steel hawsers were attached to the Russian atomic submarine Kursk when it was raised from a depth of 108 meters under
the hull of the salvage vessel Giant 4. The ball valves of the nitrogen system were opened and closed using eight computer controlled HKS rotary actuators per hawser so that the load on each
hawser could be individually regulated to compensate for the
motions of the sea. This made it possible to safely tow the 150
meter submarine into the port of Murmansk in spite of the rough
weather in the Barents Sea. (Photo: Mammoet/Smit International)

Modern ships have a carefully arranged set of
ballast tank systems which allow the ships to be
trimmed for stability in any wind or weather, regardless of the load it is carrying.
The electro-hydraulic HKS “power packs” are
controlled by a computer on the bridge to open
or close the armatures which empty and fill the
ballast tanks.

the concrete into even the
most inaccessible angles.

Wherever concrete is injected, some of it misses its
target. Our hydraulic rotary
actuators are unaffected by
such problems.

With the HKS rotary actuators the drill pipes of the
deep hole hammer can be
turned to any position.

Not only the heavy drill
pipes are moved by the HKS
rotary actuator, the actuator can also easily withstand the impacts and
vibration from the drilling
without any difficulties.
Whoever wants to cut through solid rock needs
tools that can take very heavy loads. With rotary
actuators drill pipes for deep hole hammers can
be reliably placed in any position and held at a
precise angle while the drill bores into the solid
rock. The more difficult the local conditions are,
the more important the mobility of our rotary
actuators is for the heavy machinery.

With the strength of the HKS rotary actuators this concrete
conveyor belt has enough range and mobility to move the

The fire department makes
no compromises when it
comes to safety. This also
applies to their rescue
equipment.
Modern telescopic working platforms can reach
nearly 90 meters into the air. Those who work at
such heights must be sure that the platform is
100 % safe. HKS rotary actuators not only ensure this safety, but also ensure that the plat-
form can reach any position desired without jerky
movement thanks to their smooth actuation and
perfect damping.

People correctly expect extra reliability from rotary
actuators that operate 2 300 meters under sea
level. After all, installation underwater is not very
easy and long maintenance intervals are the norm.
This is no problem for an HKS rotary actuator. Since
neither water pressure nor saltwater can impair
its function, it might even outlast the offshore
platform.

HKS rotary actuators are used in the transportation sector for everything from specialized airfield vehicles to the steering of forklifts. Electrohydraulic actuators have been widely used in the
Dutch railway network for years, our rotary ac-
tuators also help load shipping containers in ports.
They are often used to open and fasten truck
platform gates because of their low weight and
favorable dimensions.

Thanks to the high torque,
even a small rotary actuator
is enough to move even
very large tree trunks.
Our hydraulic rotary actuators are excellently
suited to machines and equipment for agriculture and forestry. They are insensitive to moisture and dirt and need virtually no maintenance.
Mechanical damage, as frequently occurs with
hydraulic cylinders, is not possible for HKS rotary
actuators.

It does not matter to the HKS demolition shears whether
they are cutting concrete or steel. They are therefore well
suited to demolish steel-reinforced concrete buildings.

This HKS concrete
pulveriser is exactly the
right tool to remove steel
reinforcement from concrete.

HKS demolition shears can
be mounted in any number
of ways. This means that
even taller buildings are no
problem.
Economy and ecology go hand in hand with our
hydraulic scrap shears and concrete pulverisers:
their use greatly reduces working costs while simultaneously reducing atmospheric pollution
which is created through incineration or the dust
from demolition. With our know-how in hydraulic drive engineering, we can expand the field of
use of such equipment and extend its lifespan.

We supply our rotary actuators in a stainless steel
housing if required.
Our hydraulic rotary actuators normally work with
an working pressure of 210 bar. That is why we
carefully seal them both inside and outside. Nothing gets in, nothing gets out. And since our actuators do not emit any particles, in contrast to,
for example, electric motors, they are suitable
for use in the food processing and pharmaceutical industries.

In the chemical and petrochemical industries our
hydraulic part-turn actuators are among the most
reliable actuators for armatures. They hardly need
any maintenance, work practically free of wear,
and can be used even in areas endangered by
explosions without problems. They withstand
wind and weather and even aggressive atmosphere in the corrosion protected version.

Machine manufacturing is the classic domain of
HKS rotary actuators. Wherever work pieces are
turned, lifted, swiveled, turned over, fed or removed, tools are changed, cages with parts are
moved, or devices moved precisely into position,
we have the rotary actuator which will enable
you to exactly and precisely perform your task.

Responsible interaction characterises the way our employees work together, who come from 10 different
nations. Proof of the active, positive internal co-operation and the excellent working atmosphere lies in our
low personnel fluctuation. In this way we can keep our
know how and further develop it.

working with each other and for the benefit of each other,
treating customers and suppliers in the same way as we would
treat each other within the company and in relation to the
people in the region.

Despite all the automation the employees’ experience
and sensitivity is absolutely
essential in the production of
rotary actuators.
The three companies which form the HKS Group show how
they have used their know-how to evolve from a manufacturer
of simple rotary parts to a provider of complete attachments.
The group consists of the following companies today: Walter
Höhn GmbH, HKS Dreh-Antriebe GmbH and HKS DrehAntriebe GmbH & Co KG.
Walter Höhn GmbH is the oldest of the three companies.
Since it was founded in 1970 Walter Höhn GmbH produced
rotary, milling and toothing parts in the best German
mechanical engineering traditions. Even though the parts are
manufactured in the most modern CNC processing centres,
the spirit of the founder’s work remains alive, which meant
uncompromising dedication to precision in mechanical
production. Walter Höhn GmbH is responsible for the quality
of the components in the Group.
HKS Dreh-Antriebe GmbH is responsible for engineering
work, assembly and sales. The company has been connected
to Walter Höhn GmbH since 1985 through its Managing
Director. HKS Dreh-Antriebe GmbH’s extensive know-how has
ensured that our rotary actuators belong to the leading
products in their sector in Europe. In this area as well we
conceive solutions for special tasks together with our
customers. For example, in co-operation with the Dortmund
30
Technical University we carried out a research project
involving the perfecting of performance by hydraulic
actuators.
That’s why HKS Dreh-Antriebe GmbH is the right partner
when you require specialist knowledge for using rotary
actuators to turn, lift and move... A further important
aspect for the company is maintenance work for
customers all over the world.
In 2001 HKS’ new Business Division Recycling was
formed. On the basis of many years’ experience in
producing important components for scrap shears and
concrete pulverisers these attachments are now
completely constructed and assembled for the building
and recycling industries. Furthermore we produce spare
parts for this sector and carry out maintenance work.
HKS Dreh-Antriebe GmbH & Co. KG in Neukirch,
Lausitz, is the youngest member of the HKS Group of
companies. It started from scratch in 1996 and the
operations made a profit just three years after it had
been founded. The Saxony-based company mainly
produces larger rotary actuators. Owing to its location
HKS Dreh-Antriebe GmbH & Co KG is the ideal contact
for customers in Eastern Europe.

If you want to deliver precision then you need perfectly
maintained equipment.
6
All new developments must
prove their quality in long
term tests which have been
developed in conjunction
with Dortmund Technical
University.
7
HKS belongs to the companies which from the beginning have had themselves
certified by NIS-Zert.
7
The HKS Group companies are known for their apprenticeships with opportunities for the future and are able
to select their apprentices from a multitude of candidates. In this way our tomorrow’s qualified staff can
learn within the company.
However, the HKS Group hasn’t just gained a good reputation as an employer and trainer, its investments have
now become an economic factor in the region.
Through its innovative product strategy and the continuous expansion of its range of activities, the HKS
Group has been able to enjoy healthy and stable growth.
This success is one reason why the company will continue with its steady investment strategy.

HKS - Solutions for our customers around the world
The European market has long been the main focus of sales for the HKS Group. Since 1996 the
HKS Group has been working exclusively with HKS
Technology srl., Erbusco (BS), Italy, and in 1998
the HKS Group together with its French partner
founded the sales arm HKS France, Melun, to
serve the important French market. In the mean
time the HKS Group has sales partners in all Western European countries and direct business connections to all continents.
The HKS Group attaches a high degree of importance to
attending the most important trade fairs and exhibitions
around the world in order to do business in international
markets.
In addition to the activities in Europe, last years
strategic partnerships were forged with representations in the United States and Canada to represent our products in the North American region.
