JPS54104118A - Travelling truck - Google Patents

Abstract

PURPOSE:To ensure little driving force, and to stably travel on curved lines while preventing effects as the obstacles of a guide, etc. for providing with compelling force to other passage, by disposing a wheel with no flange and guide rings with flanges. CONSTITUTION:Guide rings 10 provided with flanges, which can hold a guide rail 2, and mounted to a base 3 in revolution-free shapes through vertical axes, at least two these guide rings 10 are installed in series in the progressive direction of the base 3, and a center of an axle 5 of a wheel 14 mounted to the base 3 in a revolution-impossible shape is located at a position parting at a fixed interval from each guide ring 10 on a perpendicular bisector between these two guide rings 10. Since an above-mentioned arrangement can use one guide rail 2, which section form exposed on the ground is small and which does not hinder other passage, as a guide, this truck can travel on curved lines, and driving force may be little, thus ensuring simple production, then obtaining economical and positive travelling on curved lines.
