SD-2000 full hydraulic crawler driving core drilling rig is mainly used for diamond bit drilling with wire line. Because of the use of foreign advanced technology, especially the mature rotation head unit, clamp machine, winch and hydraulic systems, the drilling rig is widely used. It is not only applicable to the diamond and carbide drilling of solid bed, but also to seismic geophysical exploration, engineering geological investigation, micro-pile hole drilling, and construction of small/medium wells. 1. Main Features (1) Rotation head unit is a piston motor and mechanical gear style which adopts the foreign technique. It has the wide range of speed. Max torque is 4263Nm, so it can satisfy the different project construction and drilling process. When the drill bit is stuck at the end of the hole, it can solve the problem easily by reverse hitting function. (2) Max speed of the rig is 1120 rpm with torque 680Nm. It has a high torque at high speed which is suitable for deep-hole drilling. (3) The feeding and lifting system uses the piston hydraulic cylinder to drive the rotation head directly with a long travel and high lifting force which is convenient to the deep-hole core drilling work. (4) The rotation head unit can move away from the drilling hole, match the clamp and unscrew machine and finish the rope core drilling operation easily, also it does not need the conventional second platform work, especially replace the labor force to open and close the rotation head unit when doing the slant-hole drilling operation. (5) Rig has the high lifting speed which saves lots of auxiliary time.
