China Zgyx-420A B D Hydraulic DTH Drill Rig

1. Standard power pack could be Yuchai YC4D80 or 45kw/55kw 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. All structural parts were reinforced to match the requirements of ZGYX-3500.
3. Cycloid double motors create torque up to 5500Nm that make it possible to apply broad holes range. It is widely used for bolting,casing piping and large diameter spiral drilling.
4. The high performance wet air filter together with dry filters form patented 3stages filtering system to protect the diesel engine better.
5. Two rotation speeds could be switched conveniently to meet different requirements on torque and speed.
6. Strengthened tram motor,more power for sloping, less failure rate
7. 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.
8. Standard strengthened tram motor,more power for sloping, less failure rate
