  • Patent number: 5873310
    Abstract: A loading station of a detachable chair-lift comprises two spots 22, 29 for alternate pickup of skiers 21. To give the skiers easy access to the pickup spots, the distance between the chairs is increased by grouping them in pairs in the access zones. The station may comprise two tracks 16, 17, each having a pickup spot, onto which the chairs 11, uncoupled from the rope, are directed alternately. The two pickup spots can be on the same track, one after the other, the grouping of the chairs in pairs then being modified when running between the two pickup spots so that the rear chair of the pair at the first is pickup spot comes in front at the second pickup spot.
