GPS-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.
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 needsTo life or lower mast is operated by hydraulic control quickly and reliablyMain and vice winches employ the mechanism of planetary-gear train, so the operation is simple and convenient.
|Diameter of hole||m||1.8|
|Main winch capacity (single rope)||KN||30|
|Vice winch capacity (single rope)||KN||20|
