Abstract

765,102. Electric measuring systems. AITKEN, R. L. Feb. 23, 1955 [Feb. 24, 1954], No. 5432/54. Class 40 (1). An electrical load-measuring unit, for inclusion between two parts of a load-bearing member of a crane or like apparatus, comprises a compression member 1 mounted with electrical strain gauges and having an aperture along its compression axis, a tensioned rod 3 (passing through the aperture) attached at one end to one part of the load-bearing member and bearing at its other end on one end of the compression member, and means for applying the load in the other part of the load-bearing member to the other end of the compression member. The tensioned rod 3, attached to the upper part 6 of the load-bearing member through a collar 4 and a nut 5, passes with clearance through the aperture. 2 and bears on the lower end 7 of the compression member through centring members 8, 9. The latter have coacting convex and concave surfaces as shown, and are supported on a nut 10. The load in the lower part of the loadbearing member is applied to the upper end 11 of the compression member through a U-shaped frame 12, a cover 13, a thrust-tube 14, and a thrust disc 15. Keys 17, slotted into cover 13 and into a cover on member 6, prevent rotation of the compression member relative to frame 12 and consequent fracture of a cable 16 carrying the leads to the strain gauges. The collar on member 6 also provides an emergency stop should the rod 3 be fractured.
