GZ1-Ⅲ single arm Tunneling Drill Rig

  • Drilling diameter: φ45mm-φ102mm

  • Drilling depth: 3405mm

  • Propelling beam: 360 flip

  • Total installed power: 80.2kW

Applied range:

The equipment is used in mines, hydropower, railways, highways and other fields, tunnel drilling and blasting construction, tunneling and drilling operations or bolt hole operations.


Wheeled walking system, fast transition speed

Hydrostatic drive, wheel walking system, fast transition speed, strong climbing ability.

The drill arm is positioned accurately and moves smoothly

The drill arm adopts double triangle support for direct positioning, all-round self-parallel holding function, accurate positioning and stable action.

Liftable ceiling design, safer operation

The ceiling can be raised and lowered to meet the FOPS (Falling Object Impact) requirements.

Fast drilling speed, low drilling tool consumption

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