Borehole Diameter: 6-inch
Pull/Push Back Force: 5,000-lbs/Adjustable up to 5,000-lbs
Soil Types: Sand, clay & soft rock formations
Applications: Soil sampling, geotechnical testing, exploration shot holes & auger drilling
The LST1A+ features an auger head drive in place of the standard water swivel found on the Basic and Plus units, making it particularly suitable for auger drilling and soil sampling. This fully hydraulic drill rig is mounted on a rugged, lightweight single-axle trailer complete with three leveling jacks. The unit has the capability to drill 6-inch boreholes up to 100-feet deep in normal soils using the standard auger, and up to 50-feet with the hollow stem auger. The LST1A+ can be knocked down and palletized for shipping.
- Heavy-duty welded steel frame, rotary and swivel provide added durability.
- The LST1A+ is available as basic drill rig or full drilling package.
- The LST1A+ features a convenient by-pass flow control.
- A 2,000-pound tandem axle trailer is easily towed by an ATV or Basic Utility Vehicle.
- Optional anchor kit allows pushing beyond the weight of the trailer for additional force.
- Optional soil sampling kit includes tower and cathead for standard penetration tests.
- Swivel base design swings rotary aside for quick, easy access to borehole.
