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.

Elevator cab and/or counterweight compensation rope hitch assembly

Air deflectors are mounted on the top and bottom of the counterweight assembly in an elevator system to deflect air in the elevator hoistway to the sides of the counterweight as the latter moves up and down in the hoistway. The deflectors ensure that air turbulence is not directed toward the car as the car and counterweight pass each other in the hoistway. A quieter and smoother passenger ride is thus accomplished. In an ultra high-speed elevator system, the counterweights may be completely enclosed in an aerodynamic jacket. Cable connections and compensating rope connections to the counterweight are all made inboard thereof to ensure that the counterweight is free of turbulence-inducing protuberances.
