How does a tiltrotator work?

The tiltrotator is connected directly to the excavator's arm or beneath the excavator's quick hitch. The tiltrotator is then connected to the excavator's hydraulics and electrical system. Depending on the excavator's extra hydraulics, control is adapted to suit different types of control system. The most common connection takes place via a single or double-acting extra outlet on the arm and the tiltrotator is controlled by a proportional control system known as DC2. The actual control unit (cab module) is located in the cab and the tiltrotator's functions are controlled using our MIG2 – joysticks with rollers that allow the operator stepless control of the tilt, rotation and grip functions if a grapple has been selected for the tiltrotator. Signals from the joystick and the control unit are received by solenoid valves on the tiltrotator, thus controlling the function selected.
