Abstract
Elevator compensation ropes are attached to the elevator cab frame by means of a wedge block which is mounted on a lower portion of the frame. The wedge block has a plurality of separate wedge-shaped passages thereon through which each of the compensation ropes passes upwardly. The ropes are looped over V-shaped inserts and then passed downwardly through the passages. The inserts are dropped into respective ones of the passages so as to wedge the ropes against the wedge block. The counterweight is connected to the compensation ropes with a plurality of rope deflectors which guide the ropes from a fanned out series of thimble rods to a closely spaced parallel rope array which extends from the counterweight into the hoistway pit.
