AI Technical Summary
In existing technologies, the vibration caused by surface contact of the movable wire harness bracket affects its reliability, and the lack of support for the suspended cable chain leads to excessive pressure damage, affecting its service life.
A cable carrier support for aerial work platforms was designed. Guide rollers were used to improve sliding friction into rolling friction, and the cable carrier was supported by a fixed cable carrier support to increase support and form an oil pipe channel.
It reduces vibration frequency, improves the stability of the wire harness bracket and the service life of the cable chain, enhances smoothness of movement, and provides installation positions for the oil pipe.
