Major features:
Major parts of the rig adopt mechanical transmission mode, of which the maintenance and control is simple and the cost performance is high.
Rig power is supplied by three diesel engines that adopt belt paralleling; it has the advantages of low running cost and environment pollution.
DW is installed at lower position, and it is convenient to transportation.
DW main brake is hydraulic disc brake which has big brake torque, and it's safe and reliable.
