Functionality
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by an electric motor.
The rotary movement of the electric motor is converted into a stroke movement via a transmission and a crank gear.
The piston is moved forwards and backwards by the crank gear, this compresses the air (forward movement) or generates a partial vacuum (backward movement). Due to change in pressure the percussion piston is moved forward and backwards (air cushion percussion system) and hits the tool.
The hood and operator's controls are decoupled from the percussion system by a spring system. This spring system keeps vibrations away from the operator's body if he for example presses his body against the hood while working.
