- sheaves around which main ropes are wrapped have a large diameter; further, to arrange a plurality of main ropes, it is necessary for the distance between the drive machine and the sheaves to be large, resulting in a large planar area of the hoistway. Further, to suppress the overhead dimension, it is necessary to mount a running block to the lower portion of the car to realize 2:1 roping, resulting in a rather complicated construction and high cost. Further, the dimension of the lower portion of the hoistway has to be rather large. Thus, there is a demand for a further reduction in the size of the hoistway.
- the present invention has been made in viewof the above problems. Therefore, it is an object of the present invention to provide an elevator apparatus simplified in construction and allowing a reduction in the hoistway size.
