Abstract (en)
The invention relates to a load detector having a sensor (32) for detecting a rotational angle of a rotational member (35) which performs rotational movement in accordance with variations in load. On the basis of the value detected by the sensor (32), the load detector determines the status of a cable (18, 40). As a result, fracture in the cable (18, 40) can be perceived without fail, and it is possible to avoid overburden of an elevator system, which would otherwise be caused by ascending/descending of a passenger car while the same remains in an overloaded state. <IMAGE>
