Abstract
Abstract The invention relates to a detachable grip chairlift or gondola lift terminal having a transfer rail extending between the downhill run and the uphill run of the cable. The chair trucks run at slow speed along the transfer rail which comprises a movable rail section extending along the loading and/or unloading area. The level of the movable rail section may be adapted in accordance with the snow level on this area for properly positioning the chairs.

Total Claims: 6
Claim 1
Independent Claim
338 words
A terminal for an aerial ropeway, in particular a chairlift or a gondola lift, having an endless continuously moving cable extending along uphill and downhill runs, and trucks with detachable grips for selectively coupling the chairs or gondolas to said cable, the terminal comprising: a cable return sheave, a transfer rail extending in the terminal between the uphill and the downhill runs of the cable, said trucks being uncoupled from the cable in the terminal and running on said transfer rail, a grip release located at the entrance of the terminal adjacent said transfer rail for actuating a detachable grip to uncouple a truck from said cable, said transfer rail including successively a first section located at a first level adjacent the entrance of the terminal and having decelerating means for decelerating the truck uncoupled from the cable, a second section inclined downwardly relative to said first level, a third substantially horizontal adjustable section located at a second level, a fourth section inclined upwardly relative to said first level, and a fifth section located at the first level adjacent the exit of the terminal and having accelerating means for accelerating the truck uncoupled from the cable to synchronize the speed of the truck with the speed of the cable, a grip actuator located at the exit of the terminal adjacent said transfer rail for actuating said detachable grip to couple the truck onto the cable, truck drive means for driving the truck along the transfer rail at slow speed, a loading and/or unloading area located along said third horizontal section, a framework on which said return sheave, said first and fifth sections, said grip release and said grip actuator are rigidly secured at said first level for the free passage of the chairs or gondolas therebelow regardless of the snow level in said terminal, and lifting means linked to said third section for adjusting said second level of the third section relative to the first level in accordance with the snow level at said loading and/or unloading area.

Claim 4
Dependent Claim
25 words
The terminal according to claim 1, wherein said lifting means comprises lifting jacks having a power supply means for lifting in synchronism said third section.
Claim 5
Dependent Claim
23 words
