Lone Star - Model LST1G+HD -Soil Sampling Drill
The LST1G+HD geotechnical drill rig offers enhanced power and capabilities compared to the LST1G+, including a planetary reduction gearbox for up to 1,100 foot-pounds of torque, increased pull/push-back force and a strengthened steel frame. The drill includes a tower, cathead, pulley and 140-pound manual safety hammer to facilitate standard penetration testing. A 25-horsepower Honda gas engine with EFI and electronic governor powers the 3,000-psi hydraulic system, which achieves a rotary speed of 100 rpm with as much as 1,100 foot-pounds of torque. The drill can be mounted to the bed of a small truck or flatbed using specially designed frames.
