There is described a dumping device for use in a system for tumbling products, such as concrete blocks, bricks, paving stones or the like loaded in successive layers on a pallet. The dumping device comprise a pallet receiving structure pivotally mounted on a fixed frame, the structure including a tilting and a movable floor that receives the pallet with the layers of products thereon. The structure is first tilted to a predetermined angle corresponding to a product unloading position; thereafter, the floor is pushed intermittently so that the layers are unloaded in succession layer by layer onto a product conveying station and, thereafter, to a tumbler. Sensors are provided to indicate the presence or absence of the products at the conveying station and to give a signal to intermittently actuate the floor.
