The Schramm T450MIIA Rotadrill is a top head drive, truck mounted drill rig engineered primarily for applications using combination air rotary, mud rotary and DTH hammer drilling methods. The truck engine provides reliable power for all hydraulic, mud and air systems.  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.

The T450MIIA is well suited for water well construction in unconsolidated formations as well as monitoring well construction and environmental drilling investigations using mud, air and auger methods.
