1. Integrated configuration, compact structure and convenient operation

Except for the slurry mixing system, the power setting and hydraulic system are both placed _disibledevent="mso-spacerun: yes">  greatly reduce the risk of damage to the road surface; the electro hydraulic proportional control and running speed can be adjusted steplessly; and it is sure that both chassis run synchronously and can go up and down the flat truck safely.

2. Electro hydraulic drive, total electric control, portable operation and wide visual field.

Hydraulic components of various actuating devices are controlled by solenoid valves with portable operation and rapid response. 

3. Stepless adjustment to rotation, feeding and running speed is realized through the electro hydraulic proportional control.

"Variable capacity pump + proportional valve” has been adopted to realize the control of rotation, feeding and running speed, stepless speed changing and rapid response.

4. Mass flow hydraulic oil cooler guarantees that the system can work for a long time in high temperature stably;

"Large oil tank + mass flow hydraulic oil cooler” promotes heat dispersion of hydraulic oil in time , reduces wearing of hydraulic components and avoids leakage of sealing components. Even in high temperature climate, it can gurantee that the hydraulic system works for a long time normally and steadily.

5. Electrical controlled switch-zoom and feeding back drag speed changing can satisfy the demands of different working procedures and operating conditions in the process of constructing.

Through changing fuel supply mode of motors, it is easy to realize the change of rotation and feeding back drag speed to meet requirements in different working procedures and conditions, such as drilling, rotating, back dragging, loading poles, unloading poles, different stratums and hole expansion diameters, etc. 

6. Mighty make-up and break-out devices ensure make-up and break-out with perfect safety;

7. "Motor-chain” feeding and back drag system realizes smooth running and durable service;

8. Floating power head trailing bar avoids normal wear of drill rod screw threads;

9. Alternative  is used for the construction of pilot holes in cobbles and gravels, rocks and backfill miscellaneous soil;

10. Stochastic "hydraulic make-up and break-out wrench” is used in off machinery drill rod and demounting of drill tools, which greatly reduces labor intensity of the operation staff.
