Abstract
A weighing apparatus for determining the weight of a load while the load is in vertical motion, comprising a stationary support, a lifter for lifting and lowering the load thorough a range of vertical motion, and at least three elongate weigh beams secured to the stationary support and the lifter by respective opposite ends thereof and rigidly spacing the lifter horizontally from the stationary support. The weigh beams sense the weight of the load continuously while the load is in motion. A computer is operatively connected to the weigh beams for receiving and processing weight information sensed by the weigh beams and outputting data representative of the weight of the load. A first weight is sensed representing the container and refuse contained in the container. A second weight is sensing after the container has been emptied and subtracted from the first weight to derive a net weight representing the weight of the emptied refuse. The lifter includes a reader for reading data from an identity tag carried by refuse containers to be emptied.
