Product List




The HYG-2 full hydraulic engineering exploration drilling rig is suitable to the following fields of construction, highway, bridge, water conservation and mine as well as tunnel engineering. It can be used to foundation survey hole, deep foundation pit anchor hole, foundation reinforcement hole, road and dam foundation reinforcement hole, drainage hole, open-air quarrying blast hole and the engineering exploration hole.


The HYG-2 full hydraulic engineering exploration drilling rig is made up of diesel power station, hydraulic pressure, control system, unit head and feeding system as well as wellhead clamp, etc.


1. Driven by full hydraulic pressure, the HYG-2 full hydraulic engineering exploration drilling rig is steel crawler mounted, one-piece structured drilling rig.
2. The function of the principle arm is complete. It can move upward and downward. It can swing left or right. It can also stretch out and draw back.
3. The hub-like structure ensures the mast and the mast carrier move in accordance with each other.
4. The mast is flexible to move on the mast carrier, such as sliding or swinging.
5. The unit head is driven by hydro-cylinder with the assistance of the chain multi-speed mechanism and its balance is reinforcement by the double chains.
6. The unit head is one-piece faucet structure. As for its input, it is equipped with double motors and can produce large torque at low speed. The unit head enjoys multi-functions:
(1) It can reverse the hydro-cylinder.
(2) It can make spindle maintain the state of floating.
(3) The sliding clearance can be compensated and adjusted.
(4) It can carry out the function of top drive transmission.
7. The drilling rod can carry the function of clamping and screwing off.
8. Its hydraulic pressure, electric and mud system is one-piece distributed. As a result, they can be controlled conveniently.
9. Thanks to its compact structure and light weight, the drilling rig is effortless to be transported。
