The world's largest tonnage XCMG homemade chassis rotary drilling rig new offline

In August 29th, in XCMG foundation piling machinery branch, the world's largest tonnage homemade chassis XCMG XR550D rotary drilling rig successfully offline, once again updated the homemade homemade chassis rotary drilling rig records.

The birth of XR550D rotary drilling machine not only means the further improvement of product work efficiency, but also the embodiment of XCMG foundation as the first strength of pile industry. The maximum drilling diameter of XR550D rotary drilling rig is 3.5m, the maximum drilling depth is 132M, and the maximum output torque of the power head is 480kNm. Product offline to achieve sales.

The development of the XR550D main market demand for large engineering construction of domestic super large bridge, high-speed railway and highway etc.. XR550D adopts a self-developed rotary drilling rig H type special hydraulic telescopic crawler chassis, equipped with large diameter slewing bearing, ensure the stability and convenience of the transportation of the super, chassis with swinging legs, can assist the disassembly; 132M single rope hoist technology, ensure hoist 60 tons lifting force at the same time. Effective solution to the steel wire rope, rope bite grinding, greatly prolong the service life of the wire rope; power head with common mode and mode in rock, soil and rock respectively according to the operation, improve the efficiency of construction, and the power head with automatic rotation function, speed can be continuously adjusted in normal mode and into the rock mode, suitable for the construction of the hard strata.
