Match DTH hammer: medium/high pressure series


Main Structural Features
♦ Power system adopts YUCHAI 6-cylinder 92kw diesel engine with stage II emission standard to drive hydraulic system(Optional WEICHAI 104KW diesel engine with stage III emission standard). Rotation, feeding, lifting, jack leg, pipe unloading, winch, mud etc, are all performed by hydraulic components.

♦ When drilling, can use DTH hammer to work, if use a cutter or roller bit to make a hole, can use the mud for deslagging.

♦ The working mechanism is composed of feed mechanism, top drive type rotator, slide frame (mast), centering device, pipe unloading mechanism, winch system etc.

♦ The top drive rotator is realized by the hydraulic integrated block with equal power output of bipolar torque and bipolar speed, low speed high torque and high speed low torque. To adapt to different working conditions and holes.

♦ Cylinder's plate chain feed mode is reliable and durable.

♦ Roller slide is durable.

 Axial feed pressure, feed speed and rotation speed are adjustable. 

 The winch lifting force is 1.5 tons, and the rope is 60 meters long. It can lift drill tools, tools etc, or assist in connecting and unloading drill pipe.

 Travelling system is crawler type self-propelled structure, easy to move. Crawler chassis. Steel track plate (optional with rubber block, easy to walk on the city road). The standard configuration of four high jack legs, when long-distance transportation, no need to lift the drill machine, it can load itself onto the vehicles and convenient for transportation.

 The independent hydraulic oil radiator with stepless speed regulation can ensure that the hydraulic oil will not produce high temperature when the drill is working continuously under different temperature environments, so as to improve work efficiency.

 There are four hydraulic jack legs to adjust the Angle and stability of the drill mchine body.

 There is a gradienter and a special centering device to ensure the opening accuracy.

 The air compression system has a special oil mist to improve the service life of the hammer under deep hole conditions.
