Abstract
Abstract Aerial chairlift comprising at the loading station two separate loading areas spaced apart along the travel path of the chairs. Each loading area comprises separate lanes for queuing skiers normally closed by gates. A traffic control system for controlling boarding of the chairlift is actuated by the arrival of chairs at a predetermined location for causing alternate opening of the gates so that the successive chairs are loaded at separate loading areas.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
238 words
A method of loading passenger carrying vehicles of an aerial cableway comprising: transporting a plurality of passenger carrying vehicles, including the chair or gondola portions thereof, along a single travel path from a loading station to an unloading station along transport and return runs, providing at least first and second loading areas at the loading station, spaced apart longitudinally along the single travel path of said vehicles, passing each vehicle by each of said at least first and second loading areas successively, marking each loading area for queuing skiers awaiting a vehicle into a plurality of separate lanes, the number of lanes corresponding to the number of passengers transported by each vehicle, each lane terminating at a location adjacent said travel path without interference with the vehicle, displaying a GO signal for each said lane, controlling the display of the GO signals for the lanes of each of the loading areas, so that before each vehicle travels past the loading areas the GO signals for only one loading area are activated, the display of the GO signals for the lanes of each loading areas being activated by the arrival of a vehicle at a predeftermined location only one time out of the number of loading areas, whereby successive vehicles are loaded at successive loading areas, such as one at the first loading areas and the next at the second loading area in the case of two loading areas.
Claim 2
Independent Claim
238 words
A method of loading passenger carrying vehicles of an aerial cableway comprising: transporting a plurality of passenger carrying vehicles, including the chair or gondola portions thereof, along a single travel path from a loading station to an unloading station along transport and return runs, providing at least first and second loading areas at the loading station, spaced apart longitudinally along the single travel path of said vehicles, passing each vehicle by each of said at least first and second loading areas successively, marking each loading area for queuing skiers awaiting a vehicle into a plurality of separate lanes, the number of lanes corresponding to the number of passengers transported by each vehicle, each lane terminating at a location adjacent said travel path without interference with the vehicle, displaying a GO signal for each said lane, controlling the display of the GO signals for the lanes of each of the loading areas, so that before each vehicle travels past the loading areas the GO signals for only one loading area are activated, the display of the GO signals for the lanes of each loading areas being activated by the arrival of a vehicle at a predeftermined location only one time out of the number of loading areas, whereby successive vehicles are loaded at successive loading areas, such as one at the first loading areas and the next at the second loading area in the case of two loading areas.
Claim 3
Dependent Claim
38 words
The method of claim 1, further comprising: releasing said vehicles from a cable as said vehicles move into said travel path at the loading station, and slowing the rate of travel of the vehicles at the loading station.
Claim 4
Dependent Claim
50 words
The method of claim 2, further comprising: producing a signal indicating that a vehicle has cleared the passaged of the lanes of one of said at least first and second loading areas, and displaying the GO signal for the lanes of said one loading area upon detection of said signal.
Claim 5
Dependent Claim
50 words
The method of claim 1, further comprising: producing a signal indicating that a vehicle has cleared the passage of the lanes of one of said at least first and second loading areas, and displaying the GO signal for the lanes of said one loading area upon detection of said signal.
Claim 6
Dependent Claim
21 words
The method of claim 1, further comprising: locating one of said loading areas in an arcuate section of said travel path.
Claim 7
Dependent Claim
75 words
The method of claim 1, further comprising: equipping each of the lanes of each said loading area with a pivotally normally closed arresting bar, opening the arresting bars for one of the loading areas at the arrival of a vehicle at a predetermined location only one time out of the number of loading areas, and reclosing the arresting bars of said one loading area after a predetermined delay before the arrival of the following vehicle.
