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.
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. A 340/140 pound [154/63.5 kg] hammer is also available.
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, is 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.
For severe weather conditions, the CME-850X can be equipped with an all-weather ROPS cab. This cab is insulated and includes such features as an efficient heater, a defroster, a roll down left window and a windshield wiper.
