Abstract
The invention has reference to an overhead trolley, particularly for tracks in a store, its wheel running on a rail driven by a motor, where actuation of the pivoted auxiliary wheel assembly elevates the trolley to support the driven wheel of the trolley on a support wheel and the auxiliary wheel above a rail of the tracks. The trolley includes an arrangement with an auxiliary wheel, which may be pivoted manually into and out of engagement with the rail surface. Pivoting the auxiliary wheel into engagement with the rail surface has the effect of raising the drive wheel from the rail surface so that a disabled trolley may be pushed out of the way.
