An improved load scale of the type wherein a platform supporting a vehicle and a load to be weighed has a plurality of load cells disposed under and across each end of the pair of opposed ends and between the platform and a supporting surface. The improvement comprises a plurality of Z-shaped lateral support beams with each beam having an upper flange and a lower flange thereon. The plurality of Z-shaped lateral support beams extend across each end of the pair of opposed ends of the platform between the platform and the plurality of load cells such that the lower flange of the support beam carries the platform and is secured thereto, and the upper flange of the support beam spans the gap between adjacent load cells and rests across the tops thereon. A further improvement comprises a weight distribution means with a first base plate disposed upon the support surface with a plurality of second base plates being disposed above said first base plate and being separated therefrom by a sheet of material having a non-linear compression characteristic.
In a load scale of the type wherein a platform supporting a vehicle and load to be weighed has a plurality of load cells disposed under and across a pair of opposed ends thereof and between said platform and a supporting surface, the improvement comprising a plurality of Z-shaped lateral support beams having an upper flange and a lower flange thereon and extending across each end of said pair of opposed ends of said platform between said platform and said plurality of load cells with said lower flange extending under a portion of said platform, said lower flange carrying same by a region on said beam being relatively massive thereby reducing the total stress in the area on said beam carrying said platform and being secured to said platform in a region on said beam where forces reacted by the means securing same are low enabling said load scale to carry substantially large loads, and wherein the upper flange of said support beams spans the gap between adjacent load cells and rests across the tops thereon.
A load scale having a platform and a plurality of load cells disposed under and across a pair of opposed ends thereof and between said platform and a supporting surface comprising:
