T685WS ROTADRILL

T685WS ROTADRILL The Schramm T685WS Rotadrill is a world proven, heavy duty, heavy hoist, truck mounted drill rig. Separate drill rig subframe design permits stable mounting on standard trucks, the Schramm tracked drill carrier, trailers and special purpose vehicles of other manufacture.
High capacity single reduction top head drive rotation and efficient pipe handling systems make the T685WS Rotadrill ideal for the toughest drilling projects in the water well, shallow oil and gas, environmental, mineral exploration and surface mining fields, using down‐the‐hole hammer, air rotary, • 1350cfm @500 variable volume compressor
• Turbocharged and aftercooled deck engine for fuel efficiency
• 288m of on board pipe storage.
• Hydraulically retractable table that swings‐ out for quick access to the borehole
• 30 ft. top head travel COMPRESSOR
