ABSTRACT:
The invention relates to an elevator and a method for adjusting the inter-car distance in an elevator which comprises two or more elevator cars coupled to each other so as to be movable together in an elevator shaft, and in which these elevator cars are at least partly suspended by means of a common set of hoisting ropes (2). The vertical inter-car distance between the elevator cars (6and7) is adjusted by moving at least one of the elevator cars (6or7) in relation to at least one other elevator car (6or7) by pulling the elevator car to be moved upwards and lowering the elevator car to be moved downwards by means of at least one adjusting rope (13).
