PURPOSE: To minimize dependence of a load distribution in an elevator car in the case of measuring a load. CONSTITUTION: A load cell 18 and a load support 8 are sandwiched between an upper coupling plate 22 and a bottom coupling plate 15 so that the load is distributed between the cell 18 and the a support 8. Thus, dependence on a distribution of the load in an elevator car can be minimized. A threaded rod 5 is passed through the plate 22, the plate 15, a space therebetween and a coupling spring 14 and a support 20. An upper part of the rod 5 is coupled to a rope 9 of a shaft passage. The rod 5 is vertically displaced with one another by a rod stabilizing plate 26. The cell 18 and the support 8 are not surrounded by the rod 5, and technician can easily access to the cell 8 for its maintenance work. |
