Embodiment Construction

[0026] Figure 1AShown is an elevator installation 1 having at least one elevator car carrier 2 that can travel in a travel space 3 provided for the movement of the elevator car carrier 2 . The travel space 3 can be arranged, for example, in an elevator shaft of a building.

[0027] The elevator car carrier 2 is suspended from one end of the traction mechanism 6 . The traction mechanism 6 is also guided around the drive wheel 7 of the drive mechanical unit 8 and around the deflection wheel 9 . In this case, the drive mechanical unit 8 is arranged in the elevator shaft. Corresponding to the momentary direction of rotation of the drive wheels 7 , the elevator car carrier 2 is driven upwards or downwards through the travel space 3 . Alternatively, the elevator car carrier 2 can also be suspended from the traction mechanism 6 by means of one or more centrally arranged rope rollers with a suspension ratio of 2:1. Of course, those skilled in the art can also realize a higher susp...

Abstract

An elevator system includes an elevator car carrier moveable in a travel space to a plurality of floors. The elevator car carrier has a first elevator car and a second elevator car adjustably arranged thereon, as well as a drive unit. An adjustment device includes a first traction device and a second traction device, which traction devices are wound in the opposite sense onto drums of the drive unit. The distance between the first elevator car and the second elevator car can be adjusted by a rotation of the drums to adapt to varying floor distances.

Description

technical field [0001] The invention relates to an elevator installation having at least one elevator car carrier, which can accommodate at least two elevator cars. The invention relates in particular to the field of elevator installations designed as so-called double-deck elevator installations. Background technique [0002] A double-deck elevator is known from JP 2007-331871A. The known elevator has a car frame in which two elevator cars are arranged vertically one above the other. In this case, the two elevator cars each rest on a carrier with rope rollers. In addition, a drive unit is provided on the car frame in order to guide one of the hoisting ropes. The hoisting ropes are guided on one side around a carrier rope roller for one of the elevator cars and on the other side around a carrier rope roller for the other elevator car. The elevator car suspended in this way can be raised and lowered relative to the car frame by actuating the hoisting ropes by means of the ...
