ABSTRACT:
In an elevator emergency braking apparatus, a braking device main body has a main body braking surface facing a main rope and positioned at a first side of a main rope array, and a tapered surface facing the main body braking surface on an opposite side of the main rope array. An intermediate braking piece is disposed between mutually-adjacent main ropes inside the braking device main body. The intermediate braking piece is displaceable in a direction to be placed separably in contact with the main body braking surface. A wedge member is disposed between the tapered surface and the main rope array. The wedge member is separated from the main ropes during normal operation, and wedged between the tapered surface and the main ropes during braking.
