Force-moment compensating apparatus
First Claim
Patent Images
1. In a mobile load-handling apparatus having a frame subjected to changes in moments of force, a force-moment compensating apparatus comprising:
- (a) motive means for moving said frame,(b) speed-changing means for varying the speed of said motive means, in response to an electrical output signal,(c) a translatory sensor for sensing the translatory position of a load on said frame handled by said apparatus, and for producing a translatory signal commensurate with the sensed translatory position of said load,(d) an angular sensor for sensing the angular position of said load, and for producing an angular signal commensurate with the sensed angular position of said load, and(e) an electrical speed control circuit receiving and integrating said translatory signal and said angular signal to produce an output signal to actuate said speed-change means to vary the speed of said motive means commensurate with the value of said output signal.

Abstract
A force-moment compensating apparatus, particularly adapted for use with load handling apparatus, including stabilizing means, sensing means for sensing a change in value of a force-moment acting on the apparatus, and actuator means responsive to the sensing means for restoring the force-moments acting on the apparatus to a stable condition.
