Designing andproducing superiordrilling products
The Nitro Ant footclamps are a unique concept that utilize nitrogen compressed gas springs to achieve a high powered, self centralizing & compact foot clamp for diamond drilling applications. Being that the clamping is powered by hydraulic & nitrogen springs the Nitro Ant is perfect for angled as well as 90 degree drilling, no need to rely on rod weight as a fail safe to secure rods down the hole. The nitrogen spring can be set to a variant of pressures to the desire of the end user, giving flexibility in axial holding capacity up to 15 ton and with the Nitro Ant changing to the next rod size is quick and as simple as removing four pins, changing spacers and back to drilling again, saving on down time.

FOOT CLAMPS
These foot clamps are available with a rotation option so they can be utilized as a breakout tool as well as drill rod clamp. Various sizing is available to suit most rigs, although if required CE can adjust designs to fit to your rig.
The foot clamp are driven by hydraulic cylinder to create the initial clamp, once engaged the angled inserts slips take over keep the force constant as the deadweight of the drill string
holds itself in place. Giving peach of mind the clamps will hold the string through the force of gravity.
If clamps for underground drilling is required, please consider our Nitro Ant foot clamps.
