AI Technical Summary
The installation process of traditional bolt-fixed rolling fenders is cumbersome and poses risks of working at height. Furthermore, disassembling and reassembling internal components can easily lead to equipment malfunction.
The design employs a bolt hole without threads, which involves pre-drilling aligned unthreaded holes on the hull and rolling fenders, and then using a combination of wire and nuts to install and tighten the bolts inside the hull, thus avoiding high-altitude operations.
It enables rapid installation without disassembling internal components, reduces the risks of working at heights, improves installation efficiency, and reduces operational problems after equipment reassembly.
