Abstract
The invention relates to an elevator installation with a number of cars in a shaft, with a second car disposed underneath a first car. Associated with each car is a drive with a traction sheave and at least one cable strand, which is led over the traction sheave and by means of which the car is connected to a counterweight. The second car is kept in a suspension ratio of 1:1 and is connected to its counterweight by means of two cable strands associated with different sides of the second car and led over the traction sheave of the second car. A cable guiding device is provided which subjects the two cable strands of the second car to equal loading.
