Features

Imported drive axle, engineering chassis, strong climbing ability

Dana original imported drive axle, four-wheel drive walking system, heavy-duty engineering chassis, fast transition speed and strong climbing ability.

The drilling speed is fast and the drilling tool is very durable

With automatic anti-sticking function and automatic lubrication system, the drilling speed is fast and the consumption of drilling tools is low.

Working arm form-double triangle + self-parallel + square arm

The drill arm is directly positioned with triangular support, and has a full-directional self-parallel holding function, which ensures accurate positioning and stable action.

Stable and reliable hydraulic system

The main components of the hydraulic system adopt German Rexroth, American Parker, etc., hydraulic pilot control, stable and reliable.
