Machine, controller and control method

A control system for use with a machine comprising a machine body, and a load handling apparatus coupled to the machine body and moveable by a movement actuator with respect to the machine body, the control system incorporating a controller, the controller being configured to receive a signal representative of an orientation of the load handling apparatus with respect to a reference orientation, wherein the reference orientation is an absolute orientation that is configured to be fixed in space irrespective of the orientation of the machine itself and wherein the reference orientation is gravity or a horizontal level, and a signal representative of a moment of tilt of the machine, wherein the controller is further configured to issue a signal for use by an element of the machine including the movement actuator, which in response to the signal issued by the controller, is configured to restrict or substantially prevent a movement of the load handling apparatus when a value of the signal representative of the moment of tilt reaches a threshold value, the threshold value being dependent on the signal representative of the orientation of the load handling apparatus with respect to the reference orientation.
