1.The truck chassis adopts the special heavy truck chassis, the main transmit, transmission power, gearbox, sets of winch, mud pump, diesel engine and mast are set up on the chassis.
2. The rig is a rotary drilling rig with directional circulation, which is equipped with mud pump. It adopts the slurry as the washing fluid, it can drill on clay, sand and rock if it is connected with the suitable drilling bit.
3.If add an air compressor, and connect with hammer bit, the Rotary Drilling Rig can do down-the-hole hammer drilling.
4.The power of the rig comes from the independent deck Diesel engine.
5.The rig is mainly used for water well, construction, national defense building foundation, geothermic well and other foundation working;
6.After more several years of market inspection, this rig with reliable quality, simple operation, low maintenance costs. It is popular in Africa and Asia
