ABSTRACT:
The protection system for outriggers of a chassis includes a non-contact distance measuring device, associated with at least one of the outriggers and the chassis, mounted on one of the outriggers and the chassis. The non-contact distance measuring device measures the distance to the ground along a predetermined angle, and generates a warning signal based on the measured distance. A controller stops operation of the outriggers in response to the warning signal.
