Abstract

A car for an elevator in an elevator shaft is suspended substantially in the center of gravity thereof at least in a ratio of 2:1 by a carrying apparatus guided via pulleys and is guided through car guides. The car has a car base, a car roof and car walls that define a passenger space. For using the car in a machine room-free elevator, to provide a shaft cross-section as large as possible and to reduce the required shaft pit depth and/or the required shaft head height, at least a first part of one of the pulleys is located between the car base and the car roof and a second part of the pulley is located in the car base or at the same height as the car base or in the car roof or at the same height as the car roof.
