AI Technical Summary
In the processing of existing polyurethane chains, the tension of each strand of the steel wire rope is difficult to distribute uniformly, leading to localized stress concentration, fatigue damage accumulation, and structural failure risk, which affects the service life and maintenance costs of the chain.
A wire tension equalization device is used, which adjusts the tension of each wire one by one through a tension regulating motor and a slide mechanism to make it evenly distributed. The wires are fixed with locking bolts to maintain uniform tension.
This achieves uniform tension distribution in the steel wires inside the polyurethane chain, extending the chain's service life and reducing overall maintenance costs.
