Product Features

1. Equipped with two motors and planetary gear gyrator, has the characteristics of large rotary torque, high efficiency and durable.
2. Multi-way valve adopts two layers of double entrystructure, location is reasonable, easy to operate. New type of hydraulic system, propulsion, rotary speed, can shorten the auxiliary time of operation. With double motor two-speed gyrator, meet the requirements of different working conditions The prefilter, oil bath type air filter and air filter level 3, for the diesel engine working under high dust environment provides the guarantee.
3. The prefilter, oil bath type air filter and air filter level 3, for the diesel engine working under high dust environment provides the guarantee.
4. In order to adapt to different work environment and customer demand, adopting multiple specifications  of the diesel engine and electric motors to meet the various needs.
5. Drill arm, novel structure, convenient adjustment, greatly improve the area of drilling, apply to drill horizontal hole low. The lowest level hole height  300 mm.
6. Power output gear box with double gear structure of mercury.
7. Using engineering with walking motor, strong gradeability, low failure rate.
