It is used for rock drilling and medium and deep hole drilling. The drilling range is 38~76 mm.
Features
High production efficiency ,low operation cost
High-efficient hydraulic dual-buffer system improves production efficiency and protects the drilling tools and rock drills ,the maintenance intervals up to 600h,which greatly reduces operation cost.
Driving head with independent lubrication to improve production
Driving head with independent lubrication,pressure oil film lubricates each mating surface and side bolt technology improve production efficiency and reduce shutdown time.
Strong power
Motor is powerful and stepless variable,and has two-way rotation，high torque and excellent speed control.
