  • Patent number: 7966941
    Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR).

  • Patent number: 5660113
    Abstract: A support system that allows skiers and snow boarders to descend from cliffs and other elevated surfaces while eliminating the high speed impact landing after the descent. Aerial cables (10 and 12), suspended between towers (14 and 16), provide a path for transporting pulleys (18 and 20). Attached to pulleys, support lines (22 and 24) gradually carry the skier in harness (26) towards landing area (32) after the skier experiences a limited free-fall. While skiing down launch area (28), break-away attachments (46 and 48) keep the pulleys in the same plane as the sider and also retain partial slack in the support lines until free-fall begins. After siding from edge of ramp (30), the skier's weight pulls on the support lines causing the break-away attachments to release the partial slack held in each support line. The sider is in free-fall for a distance predetermined by the length of slack in the support lines.

  • Patent number: 5172791
    Abstract: A conveyor system for moving a container, such as a cash box, between a main station, such as a bank building, and one or more secondary stations, such as an automatic teller machine. The conveyor includes at least two continuous smooth tubes running between the stations. A carriage rides along the tubes on two sets of wheels to keep the carriage in the desired alignment. A bracket secures the carriage to a movable cable that runs adjacent to the tube and is entrained over a plurality of pulleys. The bracket is configured to lift the cable away from individual pulleys as the bracket passes each pulley to avoid contact between bracket and cable. A drive mechanism moves the cable to move the carriage between stations. This system is adapted to move the carriage through a tunnel in an overhead canopy or through an underground tunnel where, for example, the carriage carries a cash box to drive-up automatic teller machines.

  • Patent number: 4926754
    Abstract: A cable way for transporting suspended vehicles or cars includes a moving pulling cable and a guide element defining a long travel axis and formed at least in part as a support cable. The cable way at certain locations is adjustable in height and to both sides along the long travel axis. At the certain locations, the support cable is replaced by rigid rails. Each vehicle is supported on the guide element by a roller mechanism including a grip secured to the pulling cable with the grip connected by an articulated rocker member to travel rollers contacting the guide element. The rocker mechanism includes two guiding or steering elements pivotally displaceable relative to the long travel axis for effecting the adjustment at the certain locations. The grip generally engages the pulling cable from below and permits travel over diversion rollers located on both sides of the pulling cable.

  • Patent number: 4691642
    Abstract: The cable-car or gondola lift according to the invention comprises two upper cables (10, 12) which laterally frame the upper part of the vehicle (18). The latter bears two support parts (20, 22) articulated on a single horizontal transverse axis of the vehicle (18), each support part being able to be coupled to one of the cables (10, 12). The two cables (10, 12), for example carrier-hauling cables, move in synchronism, the vehicle (18) being able to be detached at the entry to the stations for unloading and loading at a standstill or at reduced speed. The longitudinal stability of the vehicle (18) is ensured by one or more cables staggered in height with respect to the cables (10, 12). According to an alternative embodiment, the longitudinal stability is conferred by the structure of the vehicle (18) itself, in this instance a modular structure.

  • Patent number: 4470354
    Abstract: A load-transfer device comprises a pair of rotary members each having an annular series of projecting peg-like elements, and a location member having arcuate tracks in its opposite sides to receive tip portions of the elements respectively. A wire or other elongate element extends beneath the location member and the upright parts of U-shaped clips supporting the wire are received in the spaces between the elements when the device encounters such clips, whereupon the members rotate relative to the location member to permit the clips to pass through the device.

  • Patent number: 4462314
    Abstract: A rocker arm assembly for support of the haul rope of an aerial tramway or the like is disclosed. The assembly includes rocker arms, rope supporting sheaves rotatably mounted to the rocker arms and cantilevered from an inwardly facing side of the rocker arms. The rocker arms are additionally formed with rope catching groove or recess positioned outwardly of the sheaves and having a configuration which will enable not only the rope, but a hanger arm and grip to pass over the rope catcher in the event that the haul rope derails from the sheaves. The rocker arm assembly also preferably includes a platform which acts as a mount for the rocker arms and can be used for maintainence and repair of the rocker arms and rope supporting sheaves. Additionally, the rocker arm assembly includes haul rope derailment responsive apparatus formed to shutdown the tramway operation upon derailment of the rope from the sheaves.

  • Patent number: 4440305
    Abstract: A skyline logging system wherein a skyline cable is supported at an intermediate location by an intermediate support assembly and a logging carriage is supported on the cable and is arranged to pass over the intermediate support assembly. The carriage has inwardly tapered pulleys which ride on oppositely bevelled tracks on the top edges of an upwardly-facing channel shaped member forming part of the intermediate support assembly. The top edges have ramp-like end portions. The carriage is lifted off the cable and rides on the bevelled tracks when crossing over the intermediate support assembly. The carriage can tilt laterally relative to the intermediate support assembly while riding on the bevelled tracks because of the lateral movability of the tapered pulleys on the oppositely bevelled tracks, whereby to maintain stability during passage of the carriage over the intermediate support.

  • Patent number: 4398640
    Abstract: An arcuate jack is arranged to be secured to a spar for supporting a skyline over it. A carriage assembly comprises a main carriage arranged to travel on the skyline and a secondary carriage supported on the main carriage for movement between leading and trailing ends of such main carriage. A brake is operative between the main and secondary carriages to control movement of the secondary carriage on the main carriage. The secondary carriage supports a drop line for connection to a load, and a mainline is connected to the secondary carriage for pulling the carrige assembly along the skyling. A guide for the mainline is provided on the spar and is disposed below the jack in an arrangement whereby the pull on the carriage assembly from the mainline is substantially tangent to the arcuate contour of the jack at its entrance end.
