1. The engine uses YUCHAI 75.8 KW turbocharged engine;
2. Walking Type: crawler mounted ,trailer mounted for choice.
3. Hydraulic oil pump:Parallel gearbox design separates the oil pump unit, the power supply is adequately distributed, the hydraulic system is uniquely designed, and the maintenance cost is small;
4.Rotary head device:gearbox integrated casting, dual motor power, large torque, durable, low maintenance costs;
5.Drilling machine chassis:professional digging chassis, durable, heavy bearing, wide chain plate, less damage to hard roads;
6.Lifting force:design composite tower, 3.4m long stroke, double cylinder lift capacity 18 ton.
7. Each rig is equipped with a relief valve to raise the boom to protect the cylinder and ensure work safety;
8. Each hydraulic oil pipe is covered with a protective jacket to make the oil pipe last longer.
