<p>PCT No. PCT/AU86/00167 Sec. 371 Date Feb. 4, 1987 Sec. 102(e) Date Feb. 4, 1987 PCT Filed Jun. 9, 1986 PCT Pub. No. WO86/07399 PCT Pub. Date Dec. 18, 1986.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 programmed to calculate therefrom the weight of the bucket and contents, when loaded and unloaded, to thereby provide the weight of material delivered.</p> |
