AI Technical Summary
Existing roller hoisting methods have problems such as the inability to hoist horizontally laid rollers and the inability to hoist rollers from inside the roller bore, resulting in low hoisting efficiency.
A hoisting auxiliary device was designed, comprising a central column, a propulsion section, and an expansion section. The device expands by sliding an inclined plate within the inclined groove of the central column to support the inner wall of the roller. Hoisting is achieved by combining a hook and a hanging ring, adapting to rollers in different states.
It enables efficient hoisting of horizontal or vertical rollers, improving roller transfer efficiency.
