ABSTRACT:
A stability measurement system is provided for a lifting vehicle including a vehicle frame, a turntable secured to the vehicle frame and supporting lifting components of the vehicle frame, and a turntable bearing disposed between the vehicle frame and the turntable. The stability measurement system includes a plurality of load sensors secured to the turntable bearing that measure vertical forces on the turntable bearing. A controller calculates a rotational moment applied to the vehicle frame from the turntable by processing the vertical forces on the turntable bearing measured by the plurality of load sensors. The forces are directly related to the stability of the machine. By monitoring the resulting moment according to a predetermined upper bound and lower bound, operation of the lifting machine can be controlled to substantially eliminate a tipping hazard.
