1, centralized controls system

The drilling rig has reliable hydraulic control system, All moves are centralized controled which makes it easy and convenience.

user can monitor all operating figures of diesel through dash board to make diesel runs safely and reliably.

The special hydraulic system insures that the rig moves fast in the condition of site transffer and/or withdraw from special situation.

This control system can adjust the feeding speed at any time based on different working contidions and rock layers to insure it drill the rocks with high efficiency.

quick lifting function can shorten assistant working time and improve work efficiency.

2, strong matched power

It adopts turbo four-cylinder diesel to provide strong power.

The humanization design of installation for engine part makes maintenance and repair faster and more convenience.

Hood of engine part has beautiful apperance and will protect the safety of inhaling for diesel engine utmost.

The floodlight on the top of hood can insure the rig work and move safely in the night.

3, stable and reliable propulsion power

Worm gear reductor and cycloid motor forms the propulsion of the drilling rig

The huge speed ratio of worm gear reductor makes the rig has sufficient propulsion and lifting force.

The self-latching function of worm gear reductor can insure the drill part stops at any height when lifting.

4, strong power head

The power head transmits stably with big torque by adopting planetary gear reductor and oscillating motor.

The tailor made bumper can reduce power head's impact from drilling part when percussive drilling.

Power head use idler wheel to guide direction when operating. It reduces the abrasion to guide rail and runns stably and maintains conveniently.

5, safe and stable walking mechanism

The big ground clearance makes the drilling rig excellent obatacle crossing capability.

The advanced hydraulic propelling deivce insures it has sufficient traction and climbing ability.

The suitable width of crawler belt makes it can go through easily on soft and muddy road.
