4. Configuration of main components
1. Chassis
The chassis is mainly composed of the main vehicle frame, left and right travel devices. The rear end of vehicle frame is fitted with hydraulic outriggers. The built-in planet speed reducer (with motor) is used as the travel speed reducer, which has a high output torque and a compact structure. The wired-controlled travel with two speeds adopted make it easy and safe to transfer and adjust the machine among work sites.
2. Engine system
The Cummins 194kW 6-cylinder water-cooled and turbocharged engine is selected. The max. pulling force is up to 500kN under the torque of 18000Nm.
3. Power unit
The power unit is driven by motor and speed reducer and its speed can be adjusted continuously so it is suitable for different work conditions. The power unit is fitted with damping device so that the drill stem threads are protected effectively.
4. Pusher and puller
The pusher and puller offers the feeding force or pulling force to the power unit through the motor, speed reducer and Rack-and-pinion. This mechanism is strong, reliable and stable.
5. Potent drill stem holder
6. On-board crane
7. Cab
The cab is an air-conditioned cab where the operator and direction controller can work together conformably.
8. Electrical system
It is mainly used to control the functions of rotation, pushing and pulling, vice and travel, etc,
9. Hydraulic system
