Abstract
In the present invention, the distance from a predetermined point to the center of gravity of the load and a first portion of a work machine and the distance from that predetermined point to the center of gravity of the second portion of the work machine are compared, either singly or in a combination, to a predetermined value. Optionally, the articulation angle of the machine and weight and position of the load are combined with a vehicle weight value into a stability value and the stability value is compared to an alarm value. Should an instability condition be detected, an output signal is sent to an output device to alert the operator and/or affect the movement of the machine to prevent instability of the work machine.
