A controller 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 controller being configured to receive a signal representative of the position of the load handling apparatus with respect to the machine body 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 position of the load handling apparatus with respect to the machine body.

1. A controller 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 controller being configured to receive a signal representative of the position of the load handling apparatus with respect to the machine body and a signal representative of a moment of tilt of the machine, wherein the controller is further configured to determine 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 position of the load handling apparatus with respect to the machine body, and 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. 2. A controller according to claim 1, wherein the element of the machine includes an indicator of the machine which, in response to the signal issued by the controller, is configured to display and/or sound a warning. 3. A controller according to claim 1, wherein the controller is further configured to receive a signal representative of whether one or more stabilisers of the machine are deployed, and the threshold value is further dependent on the signal representative of whether one or more of the stabilisers of the machine are deployed. 4. A controller according to claim 1, wherein the signal representative of the position of the load handling apparatus is a signal representative of an angle of the load handling apparatus with respect to the machine body. 5. A controller according to claim 1 wherein the threshold has a first value corresponding to a first angle of the load handling apparatus with respect to the machine body and the threshold has a second value corresponding to a second angle of the load handling apparatus with respect to the machine body, the first value being less than the second value and the first angle being less than the second angle. 6. A controller according to claim 1, wherein the signal representative of the moment of tilt of the machine is a signal representative of the load on an axle of the machine. 7. A controller according to claim 1, wherein the threshold value includes a first threshold value associated with one or more predetermined positions of the load handling apparatus and a second threshold value associated with one or more other predetermined positions of the load handling apparatus. 8. A controller according to claim 7, wherein the threshold value is proportional or substantially proportional to the signal representative of a position of the load handling apparatus over a range of positions of the load handling apparatus. 9. A controller according to claim 8, wherein the range of positions of the load handling apparatus is between a first and a second position of the load handling apparatus, and at least one different threshold value is used when the position of the load handling apparatus is outside of the range. 10. A method of controlling a machine comprising a machine body, and a load handling apparatus coupled to the machine body and moveable with respect to the machine body, the method comprising: receiving a signal representative of the position of the load handling apparatus with respect to the machine body and a signal representative of a moment of tilt of the machine;comparing signal representative of the moment of tilt with a threshold value, the threshold value being dependent on the signal representative of the position of the load handling apparatus with respect to the machine body; andissuing a signal for use by an element of the machine to restrict or substantially preventing a movement of the load handling apparatus in response to the issued signal when the signal representative of the moment of tilt reaches the threshold value. 11. A method according to claim 10, further comprising displaying and/or sounding a warning in response to the signal issued by a controller. 12. A method according to claim 10, further comprising receiving a signal representative of whether one or more stabilisers of the machine are deployed, wherein the threshold value is further dependent on the signal representative of whether one or more of the stabilisers of the machine are deployed. 13. A method according to claim 10, wherein the signal representative of the position of the load handling apparatus is a signal representative of an angle of rotation of a lifting arm of the load handling apparatus with respect to the machine body about a substantially fixed pivot. 14. A method according to claim 10, wherein the signal representative of the moment of tilt of the machine is a signal representative of the load on an axle of the machine. 15. A method according to claim 10, wherein the threshold value includes a first threshold value associated with one or more predetermined positions of the load handling apparatus and a second threshold value associated with one or more other predetermined positions of the load handling apparatus. 16. A method according to claim 15, wherein the threshold value is proportional or substantially proportional to the signal representative of a position of the load handling apparatus over a range of positions of the load handling apparatus. 17. A method according to claim 16, wherein the range of positions of the load handling apparatus is between a first and a second position of the load handling apparatus, and at least one different threshold value is used when the position of the load handling apparatus is outside of the range.
