Features

Large engine power and two reverse rotation gears, can easily solve the drilling work accident.

The operation handles are fixed together in reasonable layout to make it more convenient for workers to operate the machine.

Equipment with normal closed hydraulic chunk, operation is flexible and reliable

Spindle and hoist can be operated separately.

Spindle has big inner diameter, able to use big hexagonal drilling rod.
