GL726 Crawler DTH Drilling Rig

  • Applicable rock:f=6~20

  • Drilling diameter:90~130mm

  • Impact frequency:950~1500 t/min

  • Rotation torque:1500N.m

Applied range:

GL726 crawler down-the-hole drill carriage is mainly used for drilling blast holes in open-pit projects such as mining and quarrying, road construction, water conservancy and electric power. 


Well-integrated and powerful

It is of compact structure, well integrated and easy to move and its two systems are powered by a diesel engine with six cylinders.

New hydraulic technology

Using new hydraulic technology, low air consumption, large rotating torque, easy to move holes and position, at the same time, the thruster carriage has telescopic function, when drilling operations.

High working efficiency

The drilling rig has reliable performance and high rock drilling efficiency. The drilling speed on medium-hard rocks is 2-3 times that of low-pressure drilling rigs, with high efficiency and low cost.

self-propelled hydraulic DTH Drilling Rig

The carriage is supported on the ground with good stability.
