ABSTRACT:
The displacement of a shackle, which is coupled with a main rope hanging an elevator car, caused by loading of the car, is converted, through a wire, into the rotary motion of a pulley which has a substantially vertical rotating surface, and an acceleration sensor for detecting the angle of rotation of the pulley is fixedly secured to the pulley, so that the load of the car is detected from the angle of rotation of the pulley.
