Automatic SPT hammer^†

The CME-140 pound (63.5 kg) automatic hammer gives you 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.

Hydraulic rod holder and breakout wrench^†

The hydraulic rod holder and breakout system makes your job quicker and safer. The system 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.

Slide bases make the job easier and quicker

Slide base options are available for both in-out and sideways movement of the drill on the steel skid frame.

Quick mast disconnect^†

This feature, along with the quick-cabling sheave options allow you to remove the mast when working inside buildings, underneath bridges or in other low overhead drilling locations.

Patented angle drilling system^†

This unique system is especially effective for drilling underneath 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. And, since the kelly drive is always coupled to the right angle drive box, you can raise and lower the mast with the drivetrain already connected and ready to go.

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.
