on August 29, in XCMG foundation piling machinery branch, the world's largest tonnage XCMG xr550d rotary drilling rig with self-made chassis was successfully offline, once again breaking the record of domestic self-made chassis rotary drilling rig

the birth of xr550d rotary drilling rig not only means the further improvement of product work efficiency, but also reflects the first strength of XCMG foundation as a pile industry. The trend of large and small ships is polarized. The maximum drilling diameter of the xr550d rotary drilling rig is 3.5m, the maximum drilling depth is 132M, and the maximum output torque of the power head is 480knm. When the product goes offline, it will be sold

the research and development of xr550d is mainly aimed at the market demand of domestic large-scale engineering construction such as super large bridge piles, high-speed railways and expressways. Xr550d adopts the independently developed H-type hydraulic telescopic crawler chassis for rotary drilling rig, which is equipped with large-diameter slewing bearings to ensure super stability and convenient transportation against shortcomings. The chassis is equipped with swing legs, which can assist in disassembly; 132M full single row rope main winch technology ensures the main winch's 60 ton lifting force, effectively solves the problems of rope biting and rope grinding, and greatly extends the service life of the steel rope; The power head has ordinary mode and rock entry mode, which are respectively aimed at the operation of soil layer and rock layer, improving the efficiency of on-demand and on-demand inspection of construction assurance inspection service. At the same time, the power head has automatic rotation function, and the speed can be continuously adjustable in ordinary mode and rock entry mode, which is suitable for hard formation construction
