Definitions

  • the present teaching relates to a cableway support of a cableway with an access unit for people to gain access.
  • the present teaching also relates to a cableway with a number of cableway supports for guiding a conveyor cable of the cableway and with at least one cable car arranged on the conveyor cable, as well as a method for carrying out a climb-over from a cable car to the access unit or vice versa.
  • Cableways are available in a wide variety of designs, mostly for transporting people and/or goods, for example as urban means of transport or for transporting people in ski areas.
  • Funiculars are known in which mostly rail-bound vehicles are fastened to a wire cable in order to be pulled by the wire cable. The movement takes place on the ground, with funiculars mostly used on mountain routes.
  • cable cars such as gondolas, cabins or chairs are carried by one or more (wire) cables without fixed guides and moved while hanging in the air. The cable cars therefore have no contact with the ground.
  • Aerial cableways are usually used in rough terrain, mostly for mountain routes, for example in ski areas, to transport people from the valley to a mountain. As a rule, cableways have two stations between which the cable cars are moved.
  • aerial cableways one or two cable cars pulled by a traction cable commute back and forth on a conveyor cable on a route between two stations.
  • the circulating cable car has an endless conveyor cable which is constantly circulating between the stations and on which a large number of cable cars such as gondolas, cabins or chairs are suspended.
  • the cable cars are moved from one station to the other on one side and back again on the opposite side. The movement of the cable cars is therefore always substantially continuous in one direction, analogous to a continuous conveyor.
  • one or more cableway supports for guiding the (carrying/traction) cable(s) are usually arranged between the two stations.
  • Cableway supports can be designed as a steel framework construction, but also as a steel tube or sheet metal box construction.
  • a plurality of rollers for example in the form of a so-called roller set, are usually arranged on a cableway support in order to carry and guide the cable.
  • access units are often provided on the cableway supports.
  • Such access units can be designed, for example, in the form of (maintenance) platforms and/or steps and can be accessed by maintenance personnel.
  • safety devices for example railings, can also be provided in order to increase the safety for the maintenance personnel.
  • cableway supports can have a height that is between a few meters and more than 150 m.

  • a locking unit for locking the climb-over apparatus in the rest position is preferably provided on the cableway support. This makes it possible to reduce the risk of the climb-over apparatus coming loose in an undesirable manner, for example during operation of the cable car.
  • a mechanically, hydraulically or electrically actuatable locking unit enables flexible options for actuating the locking unit.
  • an actuating unit for actuating the locking unit is provided on the cableway support in order to release the locking of the climb-over apparatus in the rest position, in order to move the climb-over apparatus from the rest position into the standby position, wherein the actuating unit preferably has at least one first lever element in order to actuate the locking unit from a cable car, wherein the actuating unit particularly preferably also has a second lever element in order to actuate the locking unit from the access unit.
  • the actuating unit can also have an actuating means in the form of a cable pull or a flexible shaft. This creates flexible options for simple actuation of the locking unit.
  • the climb-over apparatus has a braking device in order to brake a movement of the climb-over apparatus from the rest position into the standby position caused by gravity, wherein the braking device is preferably mechanical, hydraulic or pneumatic. This can increase safety and can reduce the risk of injury to people.
