Embodiment Construction

[0044] exist figure 1 and 2 Shown schematically in the figure is a lifting device generally designated by the reference numeral 10, said lifting device having a shaft 12 in which a first car 14 and a second car 16 are arranged one above the other, and the first The car and the second car are movable vertically upward and downward separately from each other. The first car 14 is connected to a first counterweight 20 by means of carrying means in the form of first carrying ropes 18 . The first carrying rope 18 is guided via a first drive disc 22 , which can be driven in rotation by a first drive device 23 . The first drive device 23 comprises a drive motor and a drive brake (not shown in the figures) in a known manner. The first cage 14 can be moved vertically upwards and downwards in the shaft 12 along vertical guide rails 24 , 26 by means of the first drive disc 22 .

[0045] The second car 16 is connected to a second counterweight 30 by means of second load-bearing means i...

Abstract

The invention relates to an elevator system, comprising a shaft (12) in which at least two elevator cars (14, 16) are disposed on top of each other and can be moved up and down separately from each other, wherein each elevator car is associated with a drive device (23, 33) for moving the elevator car and a brake unit (55, 57) is disposed on each elevator car, and further comprising a safety unit (53) for monitoring the operating behavior of the elevator cars, and comprising at least one travel limiting unit, which comprises at least one stop element (54, 56) disposed on an elevator car and a retaining element (60, 64) that cooperates with said stop element and is disposed in the shaft, so as to limit the travel of the elevator car. In order to increase the transport capacity, according to the invention at least one stop element (54, 56) is disposed on at least a first elevator car (14, 16), said stop element laterally protruding from the vertical projection of the elevator car in a stop position and cooperating with a defined retaining element (60, 64), which is associated with said stop element and is disposed outside of the vertical projection of all elevator cars and which all other elevator cars moving in the shaft can pass without obstruction, and the brake unit (55, 57) disposed on the respective elevator car, or the braking action of said unit, can be deactivated when the elevator car drops below a predefined limit speed, wherein the elevator car can be decelerated to a standstill by means of the stop and retaining elements at speeds up to no more than the limit speed.

Description

technical field [0001] The invention relates to a lifting device having a shaft in which at least two cars are arranged one above the other and can be moved vertically upwards and downwards apart from each other, wherein each car is assigned a drive means for moving the cars and with braking means on each car; and safety means for monitoring the movement characteristics of the cars; and having at least one travel limiting device with at least one setting A stop element on the car and a holding element cooperating with this stop element, which is arranged in the shaft, serve to limit the travel of the car. Background technique [0002] The use of at least two cages which are arranged one above the other in the shaft and are movable vertically upwards and downwards apart from one another makes it possible to increase the conveying capacity of the lifting device. Personnel and loads can be moved with the aid of such a lifting device. A drive is assigned to each car for moving...
