摘要： A demolition apparatus for breaking up and demolishing in particular reinforced concrete comprises two shear-like cooperating, hydraulically driven jaws, whereof one has at least two and the other at least three working ledges provided with breaking teeth and which are all juxtaposed in parallel and interengage in alternating manner in the closed position. For the effective crushing of conrete, in the case of the jaw with the larger number of working ledges, the two outer ledges are in a common plane at right angles to the closing movement, while the intermediate ledges are set back with respect to the closing movement. The reinforcement of reinforced concrete can be easily cut up in the same working stroke, in that in the working position facing sides of at least two juxtaposed working ledges of the two jaws cutting tools are provided between the breaking teeth and are set back with respect to the latter in the direction of the closing movement and move passed one another in shearing manner at the end of the closing movement.

摘要： 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.
