The invention provides a trolley walking wheel which comprises an axle, an oil-less bush, a walking wheel body, a locating pad, a screw and a spring gasket. The oil-less bush is arranged in the walking wheel body and meanwhile an inner hole of the oil-less bush is matched with the axle. The locating pad is pressed on the end face of the oil-less bush through the screw and the spring gasket. The spring gasket is arranged between the locating pad and the screw. The axle is machined to be a stepped shaft, so that the shoulder standard type oil-less bush is located. Due to the fact that the angle of a vertical board on the side face of the walking wheel body is larger than 90 degrees, the trolley walking wheel makes linear contact with a rail, friction is greatly reduced, and walking is more convenient and flexible.
