Automatic SPT hammer^†

The CME-140 pound (63.5 kg) automatic hammer system provides extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. There are no ropes or cables to impede the free fall of the weight. The hammer swings from stored position to on-hole position. Since raising and lowering is done hydraulically, set up is quick and almost effortless. For maximum safety, all moving parts are enclosed, including the impact area between the weight and the anvil. Other hammer systems available including 170 pound (77 kg), 300 pound (136 kg), and 340 pound (154 kg).

Quick mast disconnect^†

This feature allows you to quickly disconnect the mast when working inside buildings, underneath bridges or in other low overhead drilling locations. Since the mast is completely separated from the upright, it doesn’t interfere with other drill functions such as the in-out slide base. With the mast in the horizontal position, you simply clamp it to its storage rack and extend the drills in-out slide base. This pulls the sockets on the upright drill frame away from the large tapered pins on the mast.

Angle drilling system for special applications^†

This unique system allows you to drill holes at various angles between horizontal and vertical. It is especially effective for drilling under ponds, storage tanks or other structures. When used with our patented Continuous Sample Tube System, you can even take soil samples while drilling angle holes. The angle drilling system will also allow you to drill vertically with the rig positioned on an uphill slope. That can eliminate the time consuming job of leveling the rig. Since the kelly drive is directly connected to the right angle drive box, you can raise and lower the mast with the drivetrain already connected and ready to go.

Hydraulic rod holder and breakout wrench^†

The hydraulic rod holder makes your job quicker and safer. It not only pivots from on-hole to off-hole positions, but also hydraulically moves in and out. For efficient operation, the breakout wrench is mounted at the pivot point of the rod holder arm. Systems available up to 6-5/8 inch (16.8 cm) capacity.

Cone Penetrometer Testing (CPT)

CPT controls allow you to easily switch from typical geotechnical drilling and sampling procedures to pushing a cone. A dedicated hydraulic circuit including detented CPT control lever, hydraulic down feed pressure and CPT feed rate controls provide precise pressure and penetration adjustments required to meet ASTM standards. A separate CPT system hydraulic pressure gauge is provided as well. Anchor points are installed below the drill feed frame so that maximum available pressure can be applied to the CPT tools. A 12-volt power source can be provided at the drill control panel to accommodate electronic devices associated with CPT procedures. Mounting for depth transducers or other related equipment can also be provided.
