Mounted on a lightweight, single axle trailer, complete with leveling jacks, the Lone Star LST1 water well drilling rig offers the perfect combination of performance and portability. Robust hydraulics and a pair of reliable Yanmar L100V air-cooled diesel engines provide ample power for rigorous drilling applications. Suitable for use in a variety of soils, the LST1 units drill a 6-inch borehole up to 300 feet. Shipping options include: fully assembled in a 20-ft container or broken down and palletized.
- Heavy-duty welded steel frame, rotary and swivel provide added durability.
- Robust hydraulic system features pullback forces of 5,000 pounds and push down forces adjustable up to 5,000 pounds for efficient drilling in rugged terrain.
- Convenient by-pass flow switch allows pushing up to maximum force when anchored.
- Its 3-way ball valve enables operator to quickly by-pass mudflow when adding pipe.
- Mast folds down for safe, convenient transportation.
- 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.
