AI Technical Summary
Traditional electric hoists lack cable protection mechanisms, making the wire rope susceptible to external pulling, friction, and compression, which can lead to damage to the outer sheath and breakage of internal wires, affecting normal use and potentially causing safety accidents.
A cable protection mechanism with lubrication and shock absorption components was designed. Lubricating oil is applied to the outside of the wire rope by a lubrication block, and lubrication is achieved by the cooperation of springs and telescopic columns. Shock absorption is achieved by the cooperation of arc-shaped shock absorbers and damping columns, thus preventing the wire rope from wearing and breaking.
It effectively prevents wire rope wear and breakage, ensures the normal use of electric hoists, eliminates safety accidents, and improves the effectiveness of use.
