The DCP 1005H tunnel type casing rotator is a new type of drilling machine developed by SEMW. It is mainly used for pile foundation construction in narrow and much limited spaces such as tunnels and bridge culverts. The pile diameter covers 500-1000mm, and the maximum pile depth is 40m, which can meet the harsh tunnel operation condition of 4m wide and 4.8m high.

The DCP 1005H casing rotator consists of two parts: the working device and the power station. both of them are equipped with crawler walking systems, which are flexible in transition and convenient for aligning piles to the lacation. During operation, the power station is connected to the working device through a hydraulic hose and a reaction fork to output power and provide strong ratary torque for the working device. The power station adopts high-power electric drive with the advantages of zero discharge and no noise. At the same time, it equipped with earth-moving device, with which the device can borrow the soil without additional equipment.
