CM458 Crawler Mounted DTH Drilling Rig
CM458 internal combustion (CM458D Electric) crawler mounted versatile anchor rig adopts diesel engine and hydraulic oil pump assemblies to provide power, allowing rigs to finish moving, rotating, propelling and lifting, as well as angle positioning. During drilling，only the percussive hammer consumes compressed air.
CM458 is applicable to all kinds of anchor supporting operation. In addition, the rig is also applicable to the grouting hole drilling for cofferdam, dam, and base reinforcement. Newly designed hydraulic clamp is a very useful device making operation easier.
