AI Technical Summary
During the hoisting of sand boxes in existing large-scale casting production lines, the wire rope is prone to detaching from the hoisting handle, resulting in a low safety factor.
An adjustable movable ring and a limit post are installed on the boom. The limit post cooperates with the positioning hole on the limit baffle to clamp the lifting rope and prevent it from falling off.
It improves the safety of the hoisting process, prevents the hoisting rope from separating from the boom, and enhances the stability and safety of the hoisting.
