Rotary Drilling Rig with Lock Pipe GR600

1.Special hydraulic telescopic crawler chassis, large diameter slewing support, with super stability and convenient transportation;
2.International well-known brand turbocharged high horsepower engine with strong power;
3.The main hoisting structure of the rear single-row rope greatly prolongs the service life of the wire rope and reduces the use cost;
4.Various drill pipe configurations can be selected to meet the construction of large-hole deep pile in hard stratum;
5.The main hoisting of single-row rope is adopted to solve the problem of wear and tear of the rope effectively, and to improve the service life of the rope effectively. A drilling depth detection device is installed on the main hoisting, and the single-layer winding rope is used to make the depth detection more accurate. The main hoist has the function of "following down" to ensure drilling speed;
6.The unique double retaining ring structure increases the guiding length of the drill pipe when it is fully extended, which not only solves the problem of easy deformation of the upper end of the steel pipe, but also increases the coaxiality and anti-body bending performance of the drill pipe when it is fully extended, and reduces the probability of inclined holes when the drill pipe is drilled under pressure.
