DETERMINING OF THE AMOUNT OF MATERIAL DELIVERED EACH OPERATIONAL CYCLE OF A SHOVEL LOADER

摘要

A method and apparatus for measuring the quantity of material delivered per cycle by a shovel loader having a bucket 22 that is moved between loaded and unloading positions. During the movement of the bucket in either direction between said positions, determinations are made of the location of the bucket with respect to two spaced points 27 and 17 on the structure 15 supporting the bucket. At the same time determinations are made as to the strain at a particular location in the support structure 15, that strain being related to total weight of the bucket and its contents. The bucket position determinations and the strain determinations are each provided as inputs to a processor 95 programmed to calculate therefrom the weight of the bucket and contents, when loaded and loaded to thereby provide the weight of material delivered.
