Drilling Equipment Available
ARD has the most comprehensive range of raise drilling equipment in Australia. All rigs are hydraulically driven to provide maximum flexibility in operation, protect the drill string and in-hole equipment and reduce usage of consumables such as bits and cutters. Set out below is detail of the rigs available to ARD clients and a summary of their capabilities. Note that the capabilities shown are nominal and will depend on the ground conditions on the site.

In addition, ARD has a substantial inventory of in-hole equipment, including rods, reaming heads and stabilisers, and a range of surface equipment such as forklifts for rod handling, a mud plant for pilot hole drilling where required and high pressure air compressors. The availability of such equipment enables ARD to gain the maximum flexibility in meeting job requirements - for example, in the event of a failure of a rod string, ARD is able to replace rods from it's inventory with only minimal interruption to the work.
