Lone Star Drills, a division of Little Beaver Inc. and manufacturer of efficient and portable drilling equipment, introduces high-torque Rineer rotary vane hydraulic motors for its LS400T+. The powerful water well and geothermal drill is Lone Star’s largest rig and efficiently drills as deep as 400 feet through hard rock and volcanic formations. The new hydraulic motor reduces rotary service time from days to less than an hour.
Lone Star offers the LS400T+ with two different Rineer motors, both providing greater torque than the drill’s previous hydraulic motor. The MV037 operates at a maximum speed of 125 rpm and is ideal for mud rotary drilling. The motor generates up to 1,030 foot-pounds of torque at 3,000 psi. The larger MV057 operates at a maximum speed of 60 rpm and is ideal for DTH hammer drilling. It offers as much as 2,200 foot-pounds of torque at 3,000 psi.
The LS400T+ delivers 15,000 pounds of pullback force — three times more than Lone Star Drills’ next largest model — and 9,000 pounds of push-down force. And at a weight of 7,700 pounds, the drill requires less anchoring than lighter trailer-mounted rigs. It also accommodates 10-foot drill pipe, which allows crews to quickly reach target depth.
