The system is for use in a front loader assembly for refuse vehicles, which include two spaced fork members which are secured to a cross-member, which in turn are supported by lift arms which move the load supported on the forks into the refuse truck. The system includes flexure beams which are formed by cutout portions in a sensing portion of each fork. The flexure beams are located symmetrically about a centerline of a sensing section of each fork, and alternate between two different lengths, with the flexure beams of each length being in alignment. Three sets of long cutout portions and 3 sets of short cutout portions are included, in addition to a central pair of cutout portions on which the strain gauges are mounted. The sensing section of the fork is configured to provide the necessary stiffness with the plurality of flexure beams therein.

1. An assembly for use in an on-board weighing system for front loading vehicles having a front loader assembly, comprising:two spaced fork members upon which a load to be weighed is received, the fork members being secured to a cross-member which is supported in the vicinity of the respective ends thereof by lift arm portions of the front loader assembly which are mounted on the vehicle and which move the load into the vehicle action of a motive means for lifting said lift arm portions; and load sensor means positioned on the fork members for monitoring deflection in sensing sections in each fork member, the sensing sections each including a plurality of overlapping, parallel flexure beams, defined by closed slots in the sensing sections, located above and below a centerline of the sensing section in each fork member.
