GL-3000 full hydraulic engineering crawler drilling rig

Description

The Drilling Rig, model type GL-3000, is mainly applied for core drilling of geological exploration in tunnel (gallery). It can also be used for exploration and reinforcement constructions (including core drilling and standard penetration) of foundation works, such as road, railway, bridge, dam foundation and industrial & civil projects, etc. The characteristics of this machine is obvious: advanced direct-acting hydraulic system of load feedback tuning variables, with vertical rigs, power head rotation and speedup display, wide range of speed and suitable for various drilling methods such as carbide bit drilling and diamond bit suitable for anchor construction. For difficult geological situation, drilling with casing can be fulfilled with down hole hammer and casing drilling tool. The rig is functionally complete, easy to operate and powerful in solving accidents.

Features

High efficiency and low power consumption since the power changes with load with direct-acting hydraulic system of load feedback tuning variables.

Quick and precise in hole defining and positioning with accurate vertical rig, power head rotation and speedup display device.

Convenient and fast in travelling with crawler walking function.

Easy regulation, wide speed range with high efficient fully hydraulic power head transmission and variable speeds.

Compact, ideal for tunnel (gallery) drilling.
