1. Standard power pack could be Yuchai YCD4R22T or 55kw and 22kw electric motors. Standard 76mm x 3m drill steel or variety of spiral rods. It equips both diesel and electric power packs which can be switched when necessary.
2. Cycloid double motors create torque up to 5600Nm that make it possible to apply broad holes range. It is widely used for bolting,casing piping and large diameter spiral drilling.
3. Two rotation speeds could be switched conveniently to meet different requirements on torque and speed.
4. Strengthened tram motor,more power for sloping, less failure rate
5. High-torque rotation unit with high and low speed switchable device, can be used in big diameter anchoring hole and DTH blasting hole drilling application.
6. The clamping and releasing device can disassemble the drill pipe and the casing automatically, reducing the labor intensity of workers and improving the construction efficiency.
