GJD-3 Whirl-Jet Drill Rig            <Back to Catalogue>

   GJD-3 Drill Rig is a new equipment for basic engineering, which perform grouting pile construction, which is used in treatment and strengthen the foundations of railway, highway, bridge, dam, industrial and civil buildings. Good in prevent the building subsidence or inclination and insulation water, plugging leak.

1.  General Structure modality

     The drill uses a mechanical swivel head unit. The swivel head move up on main tower by traction of wire rope of working hoist, and its rotation is driven by adjustable-electrical motor through a reducer box. In a range, the rotate speed can be adjusted stepless to meet requests of various technology of construction.

     To advance efficiency of working, the drill uses a structure of high-frame tower, and its rated tenor is increased to 12 meters. The drilling tower is foldaway in order to transport conveniently, and it can folded on the classis.

     The hoist unit is used to Lift or lowering the drilling tower, it is composed of main and auxiliary hoist, they are all driven by electrical motor. The main hoist is used to lift the drilling rods, and the auxiliary hoist is used to load or unload the rods. The main hoist unit can be adjusted stepless is a range that meet various request. The drill uses a form of hydraulic driven-replacement of lengthways and transverse, it can move in two directions, in line or in perpendicular.
