AI Technical Summary
The existing crystallizer hoisting equipment is prone to chain twisting during hoisting, which leads to increased wear and crystallizer swaying and tilting, posing a safety hazard.
The upper and lower lifting rings are rotatably connected, and the chain assembly is equipped with a rotating rod and double-row tapered roller bearings. The rotation mechanism eliminates torsional stress and prevents chain twisting and crystallizer shaking.
It effectively avoids localized stress concentration and wear caused by chain torsion, enhances the safety and stability of hoisting operations, adapts to changes in the spacing between hoisting points of different crystallizer models, and reduces the complexity of equipment procurement and management.
