Product Description:
crawler-mounted drilling rig is equipped with BW-250 mud pump. It's triplex mud pump. Have high pressure and large discharge, it's adapt to the big diameter and depth hole's drilling.
The main machine equipped with shift device, fore-and-aft movement by itself, convenient for operate.
Main winch and minor winch drive by hydraulic system, they are installed on the main drilling machine. Compact in frame. It's adapted to the wire line coring drilling.
The machine is mainly used for water well, wire-line coring drilling, geothermic well, general investigation and exploration. Road and tall building groundsill exploration and other foundation working.
