Product Description

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 entry structure, 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.
7.Power output gear box with double gear structure of mercury.
8..Using engineering with walking motor, strong gradeability, low failure rate.
