<p>The controller 12 in a load handling machine 1 comprising a machine body 2 and a load handling apparatus 6, 7 that is moveable with respect to the body 2 receives a signal representative of the position of the load handling apparatus 6,7 relative to the body 2, such as the rotation angle of an arm 6 about a fixed pivot, and a signal representative of a moment of tilt of the machine and issues a signal for use by an element (16 fig 2) of the machine 1, such as a movement actuator 8, 10 or a warning indicator (17 fig. 3), to control an operation of the machine 1 when the tilting moment reaches a threshold value, the threshold value being dependent on the position of the load handling apparatus 6, 7 with respect to the machine body 2. When the tilting moment reaches a threshold value movement of the load handling apparatus 6, 7 may be restricted or prevented. The warning indicator (17 fig. 3) may be visual or audible. The tilting moment threshold value may also be dependent upon the deployment of stabilizers S. The signal representative of tilting moment may be provided by a load cell measuring the load on an axle 5. The tilting moment threshold value may vary with the position of the load handling apparatus 6, 7 linearly (fig 4), linearly between two constant values (fig 5) or between two constant values with a step change (fig 6).</p> |
