ABSTRACT:
The present invention comprises a hydraulic sensing means to be used in connection with a worm/worm wheel gear arrangement for articulating a boom mounted on a vehicle. A hydraulic chamber on each side of the worm is formed by a bearing retainer and a piston. A worm thrust in the direction of either hydraulic chamber increases the fluid pressure in that particular chamber, which causes the fluid pressure in a closed hydraulic circuit to increase. The pressure increase is sensed by a fluid pressure gauge which sends a signal and/or terminates input power to the worm if the increase in fluid pressure is above a predetermined pressure.
