Accelerating the renewal of high-end equipment is the foundation of transformation, upgrading and efficiency gains. People are the subject of quality but also the most variable factor; a good product must first be guaranteed by good processes, equipment and tooling.
The company operates an intelligent equipment management platform with more than 600 handling and welding robots installed and a 95% equipment networking rate. More than 100 welding lines are in service, and automation across the full production line has reached 85%.
Fully automatic robotic welding station for inner seams of double-girder main beams
This station automates the welding of inner seams on double-girder main beams. After manual loading with rough longitudinal and transverse alignment, the workpiece is turned by ±90° on an L-arm hydraulic positioner and the robot locates and welds the seam automatically. Weld quality and the efficiency of structural welding improve markedly, with a clear advantage on inner seams in particular. It is another measure through which Henan Mine cares for its employees while raising quality and efficiency.
Robotic welding station for inner seams of single-girder main beams
In cooperation with the Beijing Research Institute of Hoisting and Conveying Machinery and with German crane experts, the company completed a flexible production line for single-girder cranes. The main beam line now delivers a finished unit every hour, cutting production time by 40% and shortening customer lead time by 50%. Since 2016 robotic welding lines have been introduced step by step, covering every type of weld on the company's standard single-girder products.
