Hydraulic rod holder and breakout wrench†

Automatic hammer†
Our 140 pound (63.5 kg) automatic hammer gives you extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. That’s because 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 are available including 170 pound (77 kgs), 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 drill’s in-out slide base. This pulls the sockets on the upright drill frame away from the large tapered pins on the mast.
