Function
The operation of a hydraulic concrete buster is described in a simplified version below:
Closing
The carrier driver operates the cutter valve, via a switch on the floor or via a joystick in the carrier, for the function »Close«. Oil is fed to the hydraulic cylinders via line »B«. The cutter jaws grip the debris. The debris is cut/broken. The piston rods reach their end position.
Opening
The carrier driver operates the cutter valve, via a switch on the floor or via a joystick in the carrier, for the function »Open«. Oil is fed to the hydraulic cylinders via line »A«. The piston rods retract. The cutter jaws open.
Turning
The carrier driver activates the carrier function »Turn«. Oil is fed to the hydraulic motor. The hydraulic motor, located in the upper part of the hydraulic concrete buster, causes the lower part of the hydraulic concrete buster to turn (cutter casing, cutter jaws, hydraulic cylinder). To achieve endless turning of the lower part of the hydraulic concrete buster, there is a rotary transmission between the upper part and buster casing. The oil flows for the functions »Open« and »Close« are transmitted through the rotary transmission.
