Product Description

Introduction of GL-4000 Crawler full hydraulic jet drill rig

GL-4000 Crawler full hydraulic jet drill rig is a kind of multifunctional drilling rig designed and manufactured for jet grouting operation and anchor rod hole drilling. It can be used for the foundation consolidation of railway, highway, abutment, and dam foundation; tunnel pipe-shed support, foundation pit support, slope protection, anchor rod hole drilling, leaking stoppage, soft foundation treatment, geological disaster government, and jet grouting. The upright is slide and meets the construction requirement of anchor rod. Drilling with casing tube could be completed by equipped with down hole hammer and overburden drilling system.

Features:

1. Pitch luffing mechanism, homework range

2. Variable hydraulic system with load feedback, low energy consumption

3. With display unit for rotating speed of top-drive head, lift speed and verticality of derrick, quickly and accurately to fix position

4. With track chassis and rotary device, easy and speedy to move

5. The major components in hydraulic system adopt the imported brand with a stable, reliable system, and they all have a long service life

6. Top-drive head driven by hydraulic, variable speed regulation, high efficiency
