Structures features

1. Diesel engine-driving hydraulic system. Travel, rotate, feed, hoist, land, lift, unload and so on are all run by hydraulic components.

2. During rock drilling operation, you can use down the hole hammer or reverse hammer(optional) that air compressor will provide wind to drive and slag. In operation, you can use hammer and common drill rod to make positive circulation operation; or use reverse hammer and double ply drill rod(intake air through the gap of the double ply, and slag through the inner tube) to make reverse circulation operation.

3. If use cutting or tri-cone bit to drill the hole, you can choose mud pump and slag with mud.

4. Working unit consists of feed system, slide guide(mast), top-driving rotary head, slide plate, centering apparatus, unloading system and hoisting system, etc.

5. Hydraulic pressure integrates the top-driving rotary machine into block to realize the power output of the torque and speed of both ends in constant power, low speed high torque and high speed low torque. In order to adapt to different site conditions and drilling diameters.
6. Rotary machine is capable of turning away from the drilling axis, and make it convenient for the winch to drop the pipe and operate.

7. Cylinder plate chain propulsion mode, reliable and durable

8. Roller slide is wearable.
9. Axial pressure, feed speed and rotation speed are adjustable.

10. The lifting ability of big winch is 4 tons. The steel rope is 60 meters long, and it can assist with lifting, dropping the pipe. The lifting ability of small winch is 1.5 tons, and can lift drill bits, tools, etc. Or assist with discharging drill rod.

11. Crawler self-driven structure travel mode, easy to move. Use crawler chassis. Steel track link(Inlaying rubber block is in option which is easy to travel on city streets).With four high landing legs as standard configuration. During long-distance transportation loaded with vehicle, it can be moved onto the vehicle directly and easy for transportation, no need to lift.
