Trolley wheels

Abstract

The invention proposes a trolley wheel comprising: a fixed base; a rotating shaft, located at the fixed base; a rotating base, with a rotating base and two supporting elements, in which the rotating base is attached to the rotating shaft; a wheel, with rollers, two second bearings arranged correspondingly on either side of the rollers, two bearing covers corresponding to the second bearings, two supporting elements, each with a support slot, arranged outside each bearing cover, a second connecting shaft and a second fixed element. The support components are arranged accordingly at the unloading slots, and each of the cover components has an anti-corrosion coating on the outside, or each of the cover components for the unloading components has an anti-corrosion coating on the outside. Therefore, the trolley wheel designed to resist corrosion can extend its service life.
