Abstract
The object of the present invention is to provide a trolley for loading able to comply with a force other than a direction of movement based on a premise of usage of a circular pipe as a rail. The present invention is a single-track suspension trolley for loading applied to a single rail, of which at least an upper half part is formed in arch, having a V-shaped groove having symmetric taper planes slanting to a center at midspan, having a drum-shaped wheel running on the rail while the taper plane of the V-shaped groove is in a contact condition with the upper half part in two points, having a flame provided with a pivot side plate enabling to roll the wheel, and having a cargo handling member provided with the flame beneath the wheel. A wheel is connected integrally with a pair of piece having a conical surface, each of which is faced or a V-shaped groove is produced at a center of a cylindrical member by abrading thereof. Further, a wheel is formed from a material such as a rubber and a synthetic resin having a sound absorption effect of a rolling noise.
