  • Patent number: 4630543
    Abstract: Motion is imparted to a car (12) by a cable (10) that runs along the length of a guideway (14) in sheaves (22). To accommodate directional changes in the guideway (14), the sheaves (22) are oriented in a range of configurations, including orientations (22C, 22D) above the cable (10). A guiderail (30) is located high on a side of the guideway (14) and imparts guidance to the car (12) via a rail follower (38) on the car. A cable clamp (54) attaches the car (12) to the cable (10) and displaces the cable (10) a large amount from the sheaves (22) to avoid impingement of the clamp (54) and sheaves (22). The cable clamp (54) is disposed so as to occupy the area defined by the rail follower (38). Cable supports (56,56), disposed forward and rearward of the cable clamp (54) displace the cable (10) by a small amount from the sheaves (22) and replace the cable (10) onto the sheaves (22). The cable supports (56,56) are disposed so as to occupy the area defined by the cable as displaced (55) by the cable clamp (54).
