Abstract
A travel drive for a trolley traveling gear of hoists has a drive train which has the properties of a freewheel as regards the direction of travel. Consequently load oscillation can be rapidly damped out because the speed of the traveling gear is not forcibly held constant during the semioscillation of the load in which it moves ahead of the traveling gear. On the contrary, the swinging load is able to drag the traveling gear behind it, accelerating it in the process, and in this way to convert oscillation energy into driving energy.
