Truck Mounted Deep Water Well Drilling Rig Introduction:
1.Road condition adaptive intellective All-terrain Off-road chassis, multi-axle steering intelligent control and multi-steering mode provide flexible steering and small steering diameter. Hydro-pneumatic suspension with a good travelling performance, which adapts severe road conditions such as muddy road, sand, snowfield, upland, etc. 

2.Full hydraulic top-drive. Output port adopts floating device, which effectively reduces the wearing of the drill stem thread, and increases service life of the drill stem. Spindle has a strong slag discharge capacity through its large drift diameter, which makes it especially adapt the reverse circulation construction.

3.The feeding system. It has a large stroke by extending completely when working, which adapts to long drill stem and long casing constructions. It retracts when travel to reduce transportation dimensions. It adopts cylinder-wire rope speed multiple feeding system with slow feeding mode, which provides slow drilling and fast lifting. With that it ensures good drilling performance and improves working efficiency.

4.The convenient stem changing mechanism, optioinal independent stem auto-change system and top-drive can use cooperatively, which realizes full automatic of stem loading and unloading, and reduces the number of workers and work intensity on the job site.

5. The advanced and efficient hydraulic control system. The independently developed load sensitivity control system can provide proper flow and pressure to the actuating mechanism according to the loading needs, which is energy efficient. It adopts the proportional control of the major movements, which makes the speed adjust conveniently. With no shock when start and stop, the control is highly accurate.

6. The efficient large torque fastening and unfastening device, it can fasten and unfasten the drill tools rapidly by using with power slip cooperatively, which realizes loading and unloading drill stem without assistance of workers and reduces work intensity.

Applications:
water well, wire-line coring drilling, geothermic well, general investigation and exploration. Road and tall building ground sill exploration and other foundation working.
