In order to enhance the safety of a cableway, in particular when a cable car passes through a cableway support of the cableway, according to the present teaching a detection device having at least one evaluation unit and at least two sensors connected to the evaluation unit is provided on at least one cableway support. A first sensor is located in the entry area of the cableway support in order to detect the presence of a cable car in a detection area of the first sensor. A second sensor is located in the exit area of the cableway support in order to detect the presence of a cable car in a detection area of the second sensor. The detection device is provided in order to detect a number of cable cars between the first sensor and the second sensor and to generate a fault signal when the detected number exceeds a predefined maximum number.

In order to enable more reliable actuation of the entry barrier (8) of a cable car vehicle (5) in a cable car station (2), at least one mechanically actuatable barrier actuation element (24) for actuating the entry barrier (8) is provided on the cable car vehicle (5), and at least one movable actuation component (28, 30) is provided in the barrier actuation apparatus (10). The actuation component (28, 30) is moved by the remote-control unit (11) upon activation of the barrier actuation apparatus (10) in order to exert an actuation force on the barrier actuation element (24), wherein the barrier actuation element (24) is moved by the actuation force in order to actuate the entry barrier (8).

A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.

A system and apparatus that eliminates the need for constructing a platform the length of a structure and further eliminates heavy machinery as a means of transportation or conveyance of a work platform. The system provides a rail member in combination with a plurality of bearing races for rolling bearings which allow the hanging platform to move by mechanical means along said supported rail member. The system provides a work platform or equipment cart that moves smoothly along the rail member from a first terminus to a second terminus as necessary for the transportation or conveyance of materials, equipment or persons.

A vehicle transportation installation by cable comprising a cable for hauling a vehicle, a fixedly mounted frame, a bull-wheel coupled to the cable and fitted rotatably on the frame so as to enable the cable to be driven, and a measurement device configured to measure at least one data item concerning movement of the bull-wheel, the measurement device being installed on the bull-wheel.

A connection device comprises a connector forming a ring with an open position and a closed position. A handle is fixed to the connector and has two extensions receiving a user's hands. The handle defines a tube extending in a first direction and a through hole arranged to pass through the tube perpendicularly to the first direction. A first end of a wire member forms a loop fixed to the connector in the tube. The second end of the wire member is fixed to the user. The connector passes through the through hole and the loop to fix the handle and the wire member to the connector.

Articulation for a supporting and guiding device for a vehicle hauling cable of a transport installation, including a first frame adapted to be attached to a support carrying a rotary roller intended to be in contact with the hauling cable, a second frame adapted to be introduced into an orifice formed within a carrying structure of the device, and at least one elastic element placed between the first and second frames and adapted to allow a pivoting movement of the first frame relative to the carrying structure, the articulation having a variable outer diameter able to decrease when the articulation is introduced into the orifice.
