Product description

The Diamec PHC 4 is a compact and powerful rig that is ideal for both underground and surface drilling. It can be fitted with a long or short feed frame and wire line, making it ideal for both conventional and wire line drilling. Using A-size ITH tools, the rig can drill as deep as 900 meters. The push-equals-pull feed cylinder allows for both uphole and downhole drilling at maximum capacity, day-in and day-out.

Note*	These figures serve as guidelines only. They are calculated with available pull/feed force, weight of drill string in water filled hole, average WOB and reserve for breaking solid core in rock with 10MPa Tensile Strength. Epiroc cannot guarantee these capacities will be reached in all working conditions due to varying factors such as ITH used, conditions of the ground and differences in operation.
