T300M

The Schramm T300M Rotadrill is a compact, maneuverable, top head drive, truck mounted drill designed to drill up to 12 inch (305 mm) diameter holes using mud rotary methods with rig mounted mud pumps and hollow stem augers, and air rotary and DTH hammer techniques using remote located air compressors. The truck engine provides reliable power for all hydraulic, mud and air systems. Separate drill rig subframe design permits stable mounting on standard trucks as well as on various trucks and special purpose vehicles of other manufacture. Rugged top head drive rotation and efficient pipe handling mean high productivity on the job site, more time spent drilling.
All functions are driven hydraulically from a PTO off of the truck engine, permitting a variety of mud pump, air and accessory system combinations. An optional deck engine powered model can be offered in place of the truck PTO.
