The trolley rides around the curve inbetween two adjacent horizontal cable engaging device which support the cable around the turn and maintain the cable in a curved configuration, The rotable cable support is protected by a casing with flared sides on the cable openings to guide the trolley into the casing, Each protruding edge of track is ramped up into the casing to guide the pulley wheels onto the tracks, The tracks may be curved metal runners supported by brackets or curved cable supported by the casing.
