  • Gondolas are usually designed as chairlifts or gondola lifts.
  • chairlifts have chairlifts with chairs to accommodate a number of people and gondola lifts have cabin vehicles with cabins to accommodate a number of people, the capacity of the cabins usually being greater than the capacity of the chairs.
  • armchairs were usually designed to accommodate two or four people. Recently, armchairs with a capacity of six to eight people have been increasingly used.

  • both an entry area and an exit area can be provided in a cable car station, or a combined entry/exit area, which can be the case, for example, with aerial tramways or large circular gondola lifts.
  • each cable car station In addition to pure chairlifts and gondola lifts, there are also so-called combination lifts, which form a combination of gondola lift and chairlift.
  • a number of cabin vehicles are used.
  • the different cable car vehicles are moved in a specific order with the same conveyor cable, for example three chairs and one cabin each.
  • each cable car station usually only has one chair entry area and one chair exit area. However, depending on where the cable car station is located, it is usually mainly either the chair boarding area used (e.g. valley station) or the chair exit area (e.g. mountain station).
  • the cable car stations In the case of combined railways, the cable car stations each have an additional cabin entry area, cabin exit area or combined cabin entry/exit area for entering the cabins and/or for exiting the cabins.
  • the safety bars can be closed during the exit from the cable car station. Before the people in the chair exit area of the other cable car station can leave the chairs again, the safety bars can be opened again. Closing and opening were often done manually, but recently they have also become more and more automatic.
  • the cabin entry area, the cabin exit area or the combined cabin entry/exit area of cable cars there is usually a platform through which passengers can get in and out of the cabins.
  • a pit immediately adjacent to the platform, in which the cabin vehicles are moved in a direction of movement along the platform.

  • the cable car 1 in turn has a plurality of cabin vehicles 5b, which can be moved suspended with a conveyor cable 3 between the cable car station 2c and at least one further cable car station (not shown).
  • a conveyor cable 3 between the cable car station 2c and at least one further cable car station (not shown).
  • the hoisting rope 3 functions both as a pull rope and as a support cable
  • other constructions are also used in gondola lifts in addition to the single-cable lift, e.g. multi-cable lifts.
  • the conveyor cable 3 serves as a pull cable and one or more support cables are additionally provided, along which cable car vehicles 5b roll by means of a suitable chassis.
  • the cable car shown is a single cable car, but of course all other embodiments are also included in the invention.
  • the conveyor rope 3 is in turn deflected in the cable car station 2c around a pulley 4, which can be driven by a (not shown) first drive unit 7a, which is part of the drive device 7 and which can have, for example, an electric machine.
  • the drive device 7 can be controlled by a control unit 9.
  • the cabin vehicles 5b can be decoupled from the conveyor cable 3 in an entrance area EB in an analogous manner after entering the cable car station 2c, moved along a guide rail 6 within the cable car station 2c by means of an auxiliary drive 8 and before exiting be coupled again with the conveyor rope 3 in an exit area AB.
  • operable cable clamps are again provided on the cable car vehicles 5b and actuating devices (not shown), for example positive guides, are again provided in the cable car station 2c.
  • the auxiliary drive 8 has a second drive unit 7b, for example an electric machine.
  • a cabin entry area KE is provided for people P to get into the cabin vehicles 5b and there is a cabin exit area KA for people P to get out of the cabin vehicles 5b, as indicated by the arrows. While entry and exit on the chairlift takes place in the direction of movement B, entry and exit on the cable car takes place transversely to the direction of movement.
  • the cabins of the cabin vehicles 5b have laterally arranged doors which open and close automatically at specified positions.
  • the cabin entry area KE is located in the direction of movement B in front of the exit area AB and extends over a certain length, for example a few meters.
  • the cabin exit area KA is located in the direction of movement B after the entrance area EB and extends over a certain length, for example a few meters.
  • the cabin exit area KA and the cabin entry area KE can be separate areas and, for example, be limited by suitable barriers 16 in the direction of movement of the cabin vehicles 5b.
  • a common area could also be provided, which simultaneously serves as a cabin entry area KE and as a cabin exit area KA.
  • a pit 18 is also provided in the cable car station 2c, in which a lower section of the cabin vehicles 5b is located during the movement of the cabin vehicles 5b.
  • the pit 18 is located at a lower level in the vertical direction than the cabin entry area KE and the cabin exit area KA.
  • the difference in level is usually in the range of 20cm to 1m.
  • the different levels enable essentially level, barrier-free access to the cabin vehicles 5b.
  • the cabin entry area KE and the cabin exit area KA are delimited by a platform edge 17 relative to the pit 18 and the cabin vehicles 5b move along the platform edge 17.
  • the cable car 1 in turn has a detection device for detecting a person P.
  • a third detection area D3 and a fourth detection area D4 are defined in the cable car station 2c.
  • the third detection area D3 is located in the pit 18 below the cabin vehicles 5b located in the cabin entry area KE.
  • the third detection area D3 extends in the direction of movement B of the cabin vehicles 5b over a fixed detection length DL along the cabin entry area KE and transversely to the direction of movement B over a fixed detection width DB.
  • the fourth Detection area D4 is located in the pit 18 below the cabin vehicles 5b located in the cabin exit area KA.
  • the fourth detection area D4 extends in the direction of movement B of the cabin vehicles 5b over a fixed detection length DL of the cabin exit area KA and transversely to the direction of movement B over a fixed detection width DB.
  • the detection width DB is set so that people P who fall from the edge of the platform 17 into the pit 18 into the respective detection area D3, D4 can be reliably detected.
  • the detection length DL is set so that the relevant area in which there is the highest risk of falling is covered by the respective detection area D3, D4. This area can be assumed to be known.
  • the detection width DB can be, for example, at least 50cm, preferably at least 1m, and the detection length DL can be a few meters.
  • the specific values depend on the structural design and size of the cable car 1 and can of course vary.
  • the detection device in turn has a sensor unit 10 which is arranged in the third detection area D3 and has a sensor unit 10 which is arranged in the fourth detection area D4.
  • the sensor units 10 are designed to generate a sensor signal X or to interrupt a sensor signal X when a person P comes into contact with the sensor unit 10.
  • the sensor unit 10 of the third detection area D3 has four sensor mats 10b, which are arranged one behind the other in the direction of movement B along the cabin entry area KE in the pit 18.
  • the sensor unit 10 of the fourth detection area D4 has four sensor mats 10b, which are arranged one behind the other in the direction of movement B along the cabin exit area KA in the pit 18.
  • the sensor units 10 of the third and fourth detection areas D3, D4 are connected to the control unit 9 in order to transmit the sensor signals X.
  • An evaluation unit 11 can in turn be provided in the control unit 9 in order to detect a person, in particular a fall of a person P, using the sensor signals X using a defined evaluation logic.
  • each sensor mat 10b can have a separate sensor interface 12, via which the sensor mat 10b can be connected to the control unit 9. If, as shown, several sensor mats 10b are lined up next to each other, then it can also be advantageous if the sensor mats 10b can be electrically connected so that only one sensor mat 10b, for example the last one, is connected to the control unit 9.
  • the sensor mats 10b can also be designed identically, so that a modular system is formed. Any number of sensor mats 10b can then be connected together to form a detection area D with a desired shape and size.
  • a sensor 10a in the context of the invention also means an electrical switch, whereby the sensor signal X in this case can be an electrical signal, for example a current or a voltage.
