overview

The special hydraulic chassis for the rotating drill with extensible crawler is provided with the excellent stability and is convenient to transport.

The imported Cummins turbo-supercharged engine is powerful, and has sufficient power reserve.

The machine adapt single row rope for main winch to figure out the wear of steel rope. extend the life-span. And high reliability.

Optional configuration according to customers' requirement, E.g: Crowd winch, Outrigger cylinder, Sleeve-driven and so on.

The rotary drive can switch from Nromal Mode, Rock Mode and Energy-Saving Mode, the user can select a corresponding mode of the rotary drive according to the specific working conditions, which can greatly improve the working efficiency and low the fuel consumption.

It is equipped with a centralized lubrication system as standard configuration to provide more convenient maintenance and make the machine a good reliability .
