Product Description

Performance Characteristics of ZR280C Rotary Drilling Rig

The design of large triangular luffing mechanism that can put the mast back is high in support position. Even under complex hard layer working conditions, the mast has small deformation and high hole-forming accuracy. The drill pipe pressurization and anti-warping device can effectively protect the drill pipe, give full play to the machine's ability and ensure the verticality of the hole. The design of Zhonglian CCDS system is adopted, and the current international advanced load sensing, load sensing and proportional control hydraulic system, make the hydraulic system perfectly match different complex construction conditions and output strongly. The main winching designed by the single-layer rope drum not only greatly improves the service life of the wire rope, but also greatly accelerates the lifting speed of the wire rope and improves the drilling efficiency. The special stable design chassis adopts heavy-duty hydraulic telescopic crawler, which has super stability and excellent walking performance with super traction design. Select world-class original accessories, complete machine reliability and power output are more excellent.
