4. Functional description
4.1 Description
The units are designed in such a way that a hydraulically actuated piston symmetrically
opens and closes two identical opposing crusher arms via a mechanical linkage system.
This allows stones or concrete parts to be broken up or reinforcing bars and reinforcing mesh
to be cut.
All Concrete Crushers guarantee full load-holding function when disconnected from the
hydraulic supply (e. g. when unintentionally decoupled; defective hose, and so on). In addition,
the guard can be removed from the unit. In this case, the operator must, however, take other
measures to protect from aking or breaking parts, e.g. by sturdy protective clothing and a
safety helmet with a face-protecting visor
