Model NO.: GPS-25
GPS GPS-series engineering drill rigGPS-series engineering drill rig is applied to large diameter cast-in-place piling with reinforced-concrete for high building, harbor, dam, bridge, basic engineering and also can drill large diameter hole of water well and engineering.Features
- This kind of rig is equipped a hydraulic device that can make can rotary and supporting plate to move away from the borehole.
- The mast is installed a guide way to the benefit of vertically of borehole and have a retraction system to move the kelly away from the center of rotary.
- It us equipped with a centrifugal mud pump system for pumping reverse circulation drilling to handle various conditions and formations and can be changed into direct circulation immediately to suit different needs
- To life or lower mast is operated by hydraulic control quickly and reliably
- Main and vice winches employ the mechanism of planetary-gear train, so the operation is simple and convenient.
