A device for monitoring a cableway installation, the installation including a carrier vehicle designed to be hauled by a cable, the device including: for detecting entry of a vehicle in a running zone, for calculating a variable representative of a running length of the cable, for comparing the calculated variable with a threshold, and determining configured to determine receipt of an event indicating exit of the vehicle from the running zone, the monitoring device being configured to transmit a malfunction signal after the calculated variable has reached the threshold and the event has not been received.

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).

In order to be able to reliably prevent the departure of a vehicle without a locking of the closure device in a cableway with a locking monitor, a second receiving device is provided in the movement direction of the vehicle after the first receiving device. After the start of the vehicle in the first station, the transponder of the vehicle enters the effective range of the second receiving device, and the transponder transmits a signal with the locking state to the second receiving device. The cableway is stopped before the vehicle leaves the first station when the signal to the second receiving device indicates a faulty lock mechanism.

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.

Apparatus, system, and methods for providing load responsive friction for a cable trolley device. An apparatus includes a housing configured to receive a cable. The housing includes a load attachment point and a friction device attached to the housing. The friction device is configured to cause deflection of the cable relative to an amount of load attached to the load attachment point.

A first conveyance arrest system includes a conveyance arrest cylinder comprising a piston rod mechanically coupled a trolley receiver. The trolley receiver engages a conveyance trolley, displaces the piston rod and pressurizes a working fluid within the conveyance arrest cylinder. The conveyance arrest cylinder comprises a port that vents pressurized fluid within the conveyance arrest cylinder and provides a vent resistance to fluid escaping the conveyance arrest cylinder. A second conveyance arrest system includes a conveyance trolley slideably coupled to a conveyance guide, and a conveyance arrest cylinder mechanically coupled to the conveyance trolley. The second conveyance arrest system also includes a conveyance stop configured to engage a stop engagement end of a piston rod and thereby pressurize fluid within the conveyance arrest cylinder in response to movement of the trolley toward the conveyance stop.
