ABSTRACT:
A running gear, in particular for chain hoists, load carrying and/or trailing cable, which includes a running rail comprising flange parts and a web part. Running wheels which are located opposite one another are supported on the flange parts of the running rail and guide rollers which are arranged on both sides in front of and behind each running wheel are vertically supported on the web part of the running rail. The guide rollers are rotatably supported in lateral wheel carriers connected below the running rail, at least one of the wheel carriers having a load suspension device connected thereto. Trapezoidally-shaped guide grooves conduct the guide rollers as the running gear moves longitudinally along the rail. The guide rollers have rounded edges which contact only a portion of the guide groove. Thus, the running gear moves steadily along the rail while the pitching and swaying movements which typically accompany the pendulum-like movement of the load are not transferred to the running gear.
