Full Hydraulic Crawler tunnel construction core drilling rig for exploration

Product Description

The Full Hydraulic Crawler tunnel construction core drilling rig for exploration , 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.

FAQ

Full Hydraulic Crawler tunnel construction core drilling rig for exploration is used in the following projects: tunnel pipe-shed,deep excavation anchoring projects, road and dam consolidation projects, holes for ground-source heat pump, hydrological and well drilling, foundation piles and geological disasters control projects, etc.

1: How long does it take to drill 50m hard rock layer?

That all depends. It is decided by the hardness of rock and your operating experience. As for the efficiency, it may need more

time to drill 50m rock layer compared with those big drilling machines with air compressor.

2: Can it be used for railway, street, bridge, dam foundation or building drilling?

Of course, GL-3000 is specially designed for railway, street, bridge, dam foundation and building drilling and engineering drilling.

if you buy it for that, it will be your best choice. It can be

used for mine exploration, too.

3: Could you train our workers?

GL-3000 is easy to be operated. After you buy our product, detailed operation instructions with video will be offered.

Wewill be responsible all the time. Also we can talk about sending engineers to help you.
