Embodiment Construction

[0032] Figure 1aAn elevator installation 1 is shown having at least one car frame 10 , which can be traveled in a travel range 2 provided for the travel of the car frame 10 . For example, the traffic area 2 can be arranged in a shaft of a building.

[0033] The car frame 10 is suspended from the end of the traction mechanism 6 . The traction means 6 are guided at least around the drive wheels of the drive. The drive is here arranged in the shaft or in a separate space. Depending on the momentary direction of rotation of the drive wheels, the car frame 10 travels up or down through the travel area 2 . Alternatively, the car frame 10 can also be suspended from the traction mechanism 6 via a centrally arranged sheave or a plurality of sheaves with a suspension ratio of 2:1. Of course, those skilled in the art can also realize a higher suspension ratio according to different requirements of the elevator equipment 1 .

Abstract

The invention discloses a lift with an absolute positioning system for a double-decker cabin. The invention relates to a lift installation (1) with a first and second cabin (11, 12) which are arranged on a cabin frame (10) so as to be displaceable symmetrically in opposite directions. Furthermore, the lift installation (1) has an information carrier (20) which is arranged along a region of travel (2) of the first and second cabin (11, 12) or of the cabin frame (10), a first sensor unit (21) which is arranged on the first cabin (11), and a second sensor unit (22) which is arranged on the second cabin (12). The invention is distinguished in that the first sensor unit (21) and the second sensor unit (22) are configured to read information from the information carrier (20) which serves to determine in each case an absolute position for the first and for the second cabin (11, 12).

Description

technical field [0001] The invention relates to an elevator with an absolute position detection system for double-deck cars according to the independent claims. Background technique [0002] JP2013-095572A discloses an elevator installation with double-deck cars. The known elevator installation has a car frame in which two cars are arranged vertically one above the other. The two cars are respectively suspended on one end of the hoisting rope. Furthermore, a drive unit is arranged on the car frame, around which the hoisting ropes are guided. The hoisting rope is here in active contact with the drive wheel of the drive. The thus suspended car can be raised and lowered relative to the car frame by operating the hoisting ropes by means of the drive unit. Thus, the two cars are positioned differently within the car frame. [0003] In order to detect the position of the car within the car frame, the elevator apparatus disclosed in JP2013-095572A is equipped with a first sens...
