AI Technical Summary

Technical Problem

The web members of existing crane truss booms are prone to damage under long-term heavy load operations. Welding replacement is complicated and time-consuming, resulting in high maintenance costs, long downtime, and affecting construction progress and equipment utilization efficiency.

Method used

The installation structure utilizes sliding blocks and threaded holes to enable quick installation and disassembly of the web members, avoiding large-area cutting and re-welding. Bolts are used for fixing, and rubber pads and magnetic blocks are combined to improve connection stability and airtightness. The support structure provides temporary support to prevent structural deformation.

Benefits of technology

It enables rapid installation and disassembly of the web members, reduces maintenance costs and downtime, improves construction progress and equipment utilization efficiency, and avoids the problem of reduced material performance due to heat-affected zones.
