A first reversing wheel 5.sub.1 is disposed at the other station, and the inner rope loop passes around it. Either two additional reversing wheels 5.sub.2, 5.sub.3 or a second, larger reversing wheel 5.sub.2, about which the outer loop passes, is/are disposed at the other station. Two outer deflector wheels direct the outer rope loop toward and away from either the two additional reversing wheels or the second reversing wheel.

Abstract: Sensors distributed along a ropeway communicate with a base station and preferably a base station computer. One type of sensor detects and signals cable misalignments from a normal line of cable traction. Preferably each cable tower has at least one such sensor. Another type of sensor is mounted on a sheave assembly and detects vibrations characteristic of disintegration within the assembly. It produces a sheave problem signal whenever such occurs. Preferably there is one vibration sensor mounted on each sheave assembly. Another type of sensor is preferably mounted on each ropeway carrier for detecting and signaling excessive swings. The sensor signals are communicated to a cable operator so that remedial action can be taken. Each carrier sensor has an RF transmitter for broadcasting its signals to RF receivers mounted on cable towers. Interface units local to sensor groups relay their signals to a base station computer that provides corresponding indicators to the cable operator.

Abstract: An overhead cable transport installation (e.g., a gondola lift or a chairlift) possesses a transfer rail in an end station on which grips of carriages are detached from the cable. At the exit of this transfer rail a coupling rail section extends parallel to the cable so that the cable is inserted between the jaws of the grip before the closing of the grip for clamping the cable. The coupling rail section comprises a safety device in the form of a sleeve partially surrounding the cable which allows the free passage of the grip when the cable is inserted between the jaws. Conversely, when the cable is outside the jaws, the grip is wedged and held back to prevent the chair from reaching the end of the transfer rail and falling down.

Abstract: A rhythm device section is controlled by a controller, which controls the travelling time of the carriage in terms of the delay or advance and repositions the carriage correctly with respect to a periodic signal synchronized with the cable. The controller in addition detects successive identical deviations and in this case triggers dephasing of the periodic signal so as to rephase it with the passing of the carriages.

Abstract: To detect impending deropement of a wire haul rope from supporting sheaves in an aerial tramway system, there is provided a magnetic assembly having sufficient field strength to support itself in a predetermined position by reason of attraction to the wire haul rope when running normally in the sheaves. When the wire haul rope begins to run off one of the sheaves toward an impending deropement, the magnetic assembly will fall from its armed position to a substantially moved position. The magnetic assembly carries at least one position-responsive switch which interrupts a detection circuit when the magnet moves to the moved position. The interruption of the detection circuit is utilized to detect the location of the potential deropement and to terminate tramway operation.

The arm (22), made of moulded material, has a rope catcher shoe (66), which protrudes on the outward facing side of the sheaves. A detector of excessive rocker arm (22) swing, due to the rope falling on the catcher shoe (66) or to a sheave being lost, is incorporated in the boss of the arm and protrudes into a shearing groove in the articulation spindle of the arm (22).

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.

Abstract: A compound frame to support a plurality of sheaves on a tower of an aerial tram with a predetermined bias between each sheave and a supported transiting cable. The sheaves are supported in paired opposed groups with each sheave of a group in substantial opposition so that the bias of each group of sheaves provides a safety factor to aid in maintaining a transiting cable therebetween. The manner of biasing paired sheave groups requires minimal forces for greater economy. An associated desheavement annunciating system is disclosed.

Abstract: A proximity detector has permanent magnets positioned within a chassis so that the axis and poles of the flux field of the permanent magnet are substantially normal to the front of the chassis. A switch is positioned along the front of the chassis proximate the magnet. The switch has contacts operable by the magnetic flux field of the magnet. A shield is positioned between the magnet and the rear of the chassis and between the switch and the rear of the chassis. The shield acts to inhibit extraneous magnetic fields from interferring with the detector operation and as a magnetic conductor to focus the magnetic flux field. The flux field of the permanent magnet is modified by a ferromagnetic object positioned at a predetermined distance from the front of the chassis to cause the contacts of the switch to operate in relation to the positioning thereof and in turn send an operate signal indicative of the positioning of the ferromagnetic object at the front of the switch to an external circuit.

Abstract: The safety device detects the derailment of a cable and/or the loss of one or more sheaves of a rocker supporting the cable. It includes a pivotable cross-piece which extends over the side-plates of the rocker and is prolonged laterally to form a component for catching the derailed cable. An appendix can form a temporary support for the cable when a sheave 10, 12 is lost. The pivoting of a crosspiece cuts the safety-line conductor to signal a problem condition.The device can be applied to a gondola lift.

Abstract: Transport installation with overhead cable and device for monitoring the cable-supporting components. With each rocker is associated a conductor wire sectioning device for cutting the safety line and extending over the length of the train of sheaves.

Abstract: A plurality of ski lifts are individually monitored and the information displayed at a central location for each of the ski lifts, and further displayed at a common location for all of the ski lifts. Each of the ski lifts is shut down in response to various unsafe conditions automatically with simultaneous production of a corresponding safety signal introduced in the common ski lift power control circuit, each of which safety signal is assigned a frequency or current so that it may be separated at a central location from other signals carried in the circuit for processing display. The safety devices will open switches to reduce the current carrying capacity of the closed power circuit and thereby disconnect the power to the ski lift drive while maintaining a substantially lower current carrying capacity in the circuit for passing the safety signals along the circuit to the central location.
