The small and versatile rig has a fixed crawler width of 1,300mm and is mounted on a rubber track that is 230mm wide. There is a remote control for tramming, and the steel frame supports four hydraulic stabilisers. "We've bought this drill for our customers' specialist geotechnical projects, specifically for rotary, rotary-percussive, coring and soil sampling requirements," said John Mayo, managing director at Skelair.
Designed for projects with restricted headroom, the mast has an overall height of 3,700mm and a stroke of 2,400mm. The rotary head has a twin hydraulic motor, with a maximum torque of 300daNm and a maximum speed of 480rpm. The 49HP Yanmar diesel engine is more than enough power for the rig's 2,780kg (2.78tonne) weight.
Mayo continued: "Demand for our rental rigs continues to increase, so we not only try to ensure we have a wide range available for our customers, but that we are providing them with the latest models that we can. The new EMCI 4.50 will sit alongside the previous model so clients will have a choice."
