Rotary Drilling Rig with Lock Pipe GR900

1.Special hydraulic telescopic crawler chassis, large diameter slewing support, with super stability and convenient transportation;
2.Engines adopt internationally renowned brands with strong power, energy saving and environmental protection. Three-package service outlets are all over the country;
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 whole machine matches reasonably, and the key parts adopt stable, reliable and high-performance international well-known brands. Such as imported hydraulic motors, imported electrical components, etc;
6.All drill pipes are made of high-strength alloy and high-quality pipes, which ensures the dimensional accuracy, excellent mechanical properties and welding adaptability of drill pipes. Secondary strengthening heat treatment for special steel pipes (such as core-jointed steel pipes) greatly improves the torsional performance of drill pipes;
7. 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 a 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, synchronization with wire rope and easy operation.
