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 power for all hydraulic, mud and air systems. 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 designed for water well construction in unconsolidated formations, as well as monitoring well construction and environmental drilling investigations using mud, air and auger methods.
