ABSTRACT:
A shovel for earthmoving equipment such as excavators, wheel loaders, etc., has two side walls, which are interconnected by a shovel bottom positioned between the side walls. The shovel bottom is at least zonally formed by a lattice-like grating, which is movably mounted on the shovel and which can be vibrated. The lattice-like grating is preferably mounted in vibration-damped manner and is driven by a hydraulic motor, which is connected to the hydraulic circuit of the excavator or wheel loader.
