Main equipment
- 1.auto-loading(optional)；
- 2.power head push-pull reinforcement is reserved；
- 3.auto anchor(optional)；
- 4.power head rotation speed two stall to adjust(high speed, low speed), push-pull 5.speed three stall to adjust(high speed, middle speed, low speed)；
- 6.track wire control walk, speed two gears to adjust(high speed, low speed)；
- 7.glass fiber reinforced plastics cover, movable operation table with canopy；
- 8.pilot valve control, movement more easier, comfortable;
- 9.Mud flow adjust valve, mud stop valve, antifreeze water tank, with water gun.
Main performance characteristics
1.Equipped with Dongfeng cummins engine, large power, stable performance, lower fuel consumption, lower noise, more suitable working in urban area.
2.Rotation, push-pull pilot control, operation more portable.
3.Driving head adopts cycloid motor from Eaton, which drives rotation directly, with large torsion, stable performance, and two stall stepless speed regulation. Driving head push-pull adopts cycloid motor from Eaton, which has three stall speed and high construction speed of which leads far ahead in fellow-competitors. The reserved reinforcement device increase construction scope.The hydraulic gear pump adopts military technique, track wire control operation, convenient and fast loading, unloading as well as construction site transition.
4.Operation table overview is broad, operation table design adopts human-computer construction way, comfortable operation, reduces fatigue strength.
5.Equipped with φ60×3000mm drill rods，moderate machine size adapts to narrow and small working area and high efficient construction as well.
6.Surface is with elegant appearance, easy maintenance, fully embody humanist designing idea.
