Product Details


GL-4000B crawler-type full-hydraulic drilling rig is a kind of multifunctional drilling rig which is mainly designed and manufactured for jet grouting operation and anchor rod hole drilling. This downhole drilling can be used for the foundation consolidation of railway, highway, abutment, and dam foundation; tunnel pipe-shed support, slope protection, anchor rod hole drilling, leaking stoppage, soft foundation treatment, geological disaster government, and jet grouting. 


1. Luffing mechanism of pitch makes the homework range wide.

2. With display unit for verticality of derrick, rotating of top-drive head and lift speed, it is available to fix position quickly and accurately to make sure the stable operation with high precision.

3. With track chassis and rotary device, the full hydraulic crawler jet grouting drilling rig  is easy and speedy to move, which can shorten the time of changing places, greatly improving the working efficiency.

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

5. Top-drive head is driven by hydraulic with stepless speed regulation which is quite high efficient.

6.  The full hydraulic crawler jet grouting drilling rig is equipped with clamping device to make sure the excellent performance with fine results.
