G3Z Three-Boom Tunneling Drill Rig

  • Drilling diameter:φ38mm-φ102mm

  • Drilling depth:5268mm

  • Telescopic length of working arm:1600mm

  • Total motor power:243.5kW

Applied range:

It is used for drilling and blasting drilling operations or bolt hole operations in large and medium-sized tunnels such as railways, highways, water conservancy, mining and other large and medium-sized tunnels.


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.

Strong engine power, it can also cope with severe cold and plateau environment

The high-altitude turbocharged engine has strong power and sufficient power reserve to meet the requirements of severe cold and plateau environments.

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.

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.
