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.
