Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
91 words
A weighing system for material handling apparatus comprising a plurality of fixed load cells and a plurality of movable load cells, said fixed cells and said movable cells being operably connected to form a three-point system, each of said fixed cells being one of two legs of the system and one or more of the movable cells being said third leg, said cells being in operable contact with the load bearing surfaces of said material handling apparatus, means connecting said cells to an averaging device, and means for recording said average.
Claim 2
Dependent Claim
91 words
A weighing system for material handling apparatus comprising a plurality of fixed load cells and a plurality of movable load cells, said fixed cells and said movable cells being operably connected to form a three-point system, each of said fixed cells being one of two legs of the system and one or more of the movable cells being said third leg, said cells being in operable contact with the load bearing surfaces of said material handling apparatus, means connecting said cells to an averaging device, and means for recording said average.
Claim 3
Dependent Claim
64 words
The weighing system of claim 1 wherein said system is comprised of two fixed cells and two movable cells at one extreme of the load bearing surface of the material handling system and a second set of two fixed cells and two movable cells, said second set being opposed as to fixed and movable cells at the other extreme of said weight bearing surface.
Claim 4
Dependent Claim
39 words
A weighing system for a material handling apparatus as claimed in claim 1 wherein said material handling apparatus includes a main support frame carrying said load cells and a spaced load bearing surface operably connected to said load cells.
Claim 5
Dependent Claim
36 words
A weighing system as claimed in claim 1 wherein at least two fixed cells are provided at spaced apart points, said fixed cells forming two suspension points and the movable cells forming the third suspension point.
Claim 6
Dependent Claim
73 words
A weighing system for a ladle crane hanger as claimed in claim 1 comprising a pair of fixed load cells fixedly attached to the opposing sides of each of the two reeving baskets of said ladle crane hanger, a pair of moveable load cells rotably attached to the remaining sides of each of said reeving baskets, means for connecting all of said cells to averaging means, and means for reading said averaging means.
