Equipment

Accelerating the renewal of high-end equipment is the foundation for transformation and upgrading as well as improving quality and efficiency. People are the theme of quality, but they are also the most unstable factor. A good product must first be guaranteed by good processes, equipment and tooling.
The company has installed an intelligent equipment management platform. Currently, over 600 sets of handling and welding robots have been installed, with a network connection rate of 95%. More than 100 welding assembly lines have been put into use, and the full assembly line automation rate of products has reached 85%.

• Fully automatic double-girder main beam inner seam robot welding workstation

  

  This workstation is mainly designed for automatic welding of the inner seams on double-girder main beams. After manual loading with approximate centering in both horizontal and vertical directions, the workpiece is rotated by ±90° via the L-arm hydraulic turnover fixture. The robot then performs positioning and welding automatically. It delivers remarkable improvements in weld quality and boosts welding efficiency for crane structural components, with outstanding performance specifically for inner seam welding. This is another initiative from Henan Mine that prioritizes employee well-being while advancing quality and efficiency.

• Single-beam main beam inner seam robot welding workstation

  

  The company has partnered with the Beijing Crane and Transport Machinery Design and Research Institute and engaged German crane specialists to develop the Flexible Production Line for Single-girder Cranes. Thanks to this line, finished crane main girders can be output hourly, cutting production time by 40% and shortening customer delivery lead time by 50%. Starting from 2016, we have gradually rolled out robotic welding assembly lines capable of completing all weld seams for our standard single-girder products.
