<P>PROBLEM TO BE SOLVED: To provide a load detection device capable of accurately detecting loading load not dependent on the form of a car. <P>SOLUTION: The load detection device 10A is the one provided on a rope hitch 9A for retaining an end of a plurality of main ropes 2 for hanging the car 6 of the elevator on a hoistway 3, and is provided with a base plate 11; a vibration-proof rubber (elastic member) 12; a target 13; and a distance measurement sensor 14. The base plate 11 has an insertion hole 111 penetrated with a shackle rod 91 and is arranged on a hitch plate 92 in parallel to the hitch plate 92 at a side where the main rope 2 is extended. The vibration-proof rubber 12 is provided between the hitch plate 92 and the base plate 11. The target 13 is fixed to the hitch plate 92. The distance measurement sensor 14 is arranged at a side where the base plate 11 is fixed, and measures a position of the target 13 along a direction that the shackle rod 91 is extended. <P>COPYRIGHT: (C)2008,JPO&INPIT |
