The LST1 Geotechnical Rig is ideal for soil sampling, geotechnical testing and environmental well drilling in limited access areas. The unit is equipped with a 4-inch-diameter auger for drilling 6-inch boreholes to depths of 100 feet, and it includes a tower, cathead and 140-pound safety hammer for standard penetration testing. It offers a lifting capacity of 5,000 pounds to ensure easy removal of augers and extensions. A Honda 20-horsepower gas engine powers the LST1 Geotechnical Rig, and the hydraulic system provides 150-rpm speed at 10-gpm. For added versatility, Little Beaver’s optional interchangeable head allows users to switch from auger to water well drilling. Another available option is Little Beaver’s Big Beaver Drill Rig.
This fully hydraulic drill rig can be mounted to the bed of a small truck or flatbed with Little Beaver’s specially designed frames. It can also be mounted on a rugged, lightweight, single-axle trailer equipped with a 2-inch hitch, three leveling jacks and a spare tire. Ship the LST1 fully assembled in a 20-foot container or knock down and palletize for transportation by truck or ocean freight.
- Heavy-duty welded steel frame, rotary and swivel provide added durability.
- The LST1 Geotechnical Rig is available as basic drill rig or full drilling package.
- LST1 Geotechnical features a convenient by-pass flow control.
- A 2,000-pound tandem axle trailer is easily towed by an ATV or small truck.
- Optional anchor kit allows pushing beyond the weight of the trailer for additional force.
- Swivel base design swings rotary aside for quick, easy access to borehole
