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.
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. 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, 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.
Fluted kelly and chuck assembly †
If your drilling operations include a substantial amount of rotary or core drilling, the CME fluted kelly and chuck assembly can save you a lot of time. The 5 foot [1.5 m] stroke of the kelly combined with the 6 foot [1.8 m] stroke of the feed system, gives you a total stroke of 11 feet [3.4 m]. You can use 10 foot [3 m] drill rods, which means fewer rod connections and less rod handling.
The kelly has two vertical slots (flutes) and two sets of horizontal slots which are engaged by the chuck to provide rotary torque and thrust. The CME fluted kelly can even be rotated without engaging the thrust keys. This gives you the option of using the weight of the drill string to provide down pressure on the bit.
The 2 5/8 inch [6.7 cm] fluted kelly and chuck assembly is available in either manual or hydraulic actuated configurations. Or if you are drilling larger diameter holes, a 3 1/2 inch [8.9 cm] O.D. fluted kelly and hydraulic chuck assembly is available.
A 468 gallon [1,771 L] stainless steel water tank includes 15 inch [38.1 cm] deep tool boxes on each side. For added convenience, removable shelves and lockable swing out doors.
Numerous water tank/tool box configurations are available, including models with rod storage capacity underneath and an expanded metal rack on top.
