The XR1600E, the world’s largest rotary drilling rig developed by XCMG has rolled off the assembly line. It was designed and put into production especially for large-scale bridge pile construction and offshore wind power piling projects.

The model has set several world records with a maximum drilling diameter of 7.5 meters and maximum drilling depth of 190 meters, and the output torque of its power head is 1600kNm.

The rotary drilling rig has a height of 42 meters and a weight of 520 tons. The XR1600E is developed with dual power source cooperative control and modular combination technology of super-large tonnage rotary drilling rigs. The drill pile features visualized anti-banding rod technology that reduces the risk of smashing rods by 95 per cent to ensure the safety of piling and foundation operations.

“The XR1600E owns more than 20 patents for invention and has fully elevated the level of construction capacity, performance, and safety, tackling the bottleneck problems of large-scale foundation construction like low efficiency and high cost that traditionally use reverse circulation drill to deliver high-quality piling performance,” said Wang Min, chairman and CEO, XCMG. “It will support the super infrastructure construction and create greater value for customers.”
