Drive System
Drive of chassis
1.The diesel engine drives the twin pump to drive the hydraulic motor through Multi-way Directional Valve and transfers to the crawler chassis, then the right and left driving gears drive the crawler chassis to travel. It rotates flexibly, convenient ,reliable ,and easy to operate.
2.The lift/fall pylonControl the lift/fall of the pylon by operating the multi-way directional valve.
3.Drilling rig operation is to operate the handle of multi-way directional valve so as to reach the position where the drilling rig is communicated with. Then the handle of drilling rig may be operated directly. The handle is placed at the stop position when it is not used.
