CCTEG
Underground
drill rigs
All hydraulic splitting rig
All hydraulic crawler rig
Hard to be moved in the
tunnel and roadway
Mature serial products
Drill depth range from 75m-
1000m
lower cost, cheaper
Easy to change sites
Integrated crawler
design
Large dimension
increases space require
of the roadway and
drill sites
1. Introduction
CCTEG
1. Introduction
Destressing
boreholes from floor
Drivage covering borehole
Gas drainage (drill
boreholes from the
roadway under seam floor)
CCTEG
1. Introduction
Drill rig requirement
Small dimension in size especial in width
Extensive azimuth and inclination angle adjustment
High drill capacity (torque, feed/pull force) and efficiency
Solution
Using splitting crawler structure to reduce each unit’s
dimension
Special designed structure to achieve wide range of azimuth/
inclination adjustment
Rated torque of the rig should reach 4300 Nm
Rated pull force should reach 120kN
High quality hydraulic components, Rexroth and Sauer

3.Technical Features
Climbing experiment
Excellent climbing ability
Rig can climb hills as slope as 15°
CCTEG
3.Technical Features
①Mature Constant pressure variable displacement control system
② High quality hydraulic components(Rexroth and Sauer)maintain system reliability
③ Linkage system and optimized pressure/flow rate control lead to
simple operation
Reliably hydraulic system
