Embodiment Construction

[0027] figure 1 Shown is a schematic perspective view of a part of an elevator installation 100 with two parallel-extending support elements 1a, 1b, which includes an elevator car 20 and a 2:1 arrangement (Konstellation) of countermoving arrangements. Heavy items5. A front support means 1a forms a support loop 4a from a first fastening point 2a at the shaft ceiling 11 of the elevator shaft 10 to the driving pulley 3a, in which counterweight 5 supports the rollers by means of a counterweight 6a while running. This form of suspension of the counterweight presents a 2:1 suspension.

[0028] The term "drive pulley" 3a, 3b here also refers to a drive shaft which is made in one piece and on which the two supporting means 1a and 1b run.

[0029] The support means 1a additionally forms a second support loop 4b from the driving pulley 3a to a second fixed point 2b at the shaft ceiling 11, in which the elevator car 20 is carried on the car support rollers 7a and 7b on. This type of...

Abstract

An elevator installation can comprise an elevator cage, a counterweight, a first support, a second support, a drive for driving of drive pulleys in common and for movement of the supports, and a monitoring device with two slack support switches. A first slack support switch is arranged in the region of a first fastening point for monitoring the first support. A second slack support switch is arranged diagonally opposite in the region of another fastening point for monitoring the second support. The monitoring device comprises a safety circuit, in which the two slack support switches are so integrated in a safety circuit of the elevator installation that actuation of just one of the two slack support switches interrupts the safety circuit.

Description

technical field [0001] The invention relates to an elevator installation in which a monitoring device or device is provided for operating state monitoring of support means on the cage side and on the counterweight side of the elevator installation. Background technique [0002] An elevator installation generally includes an elevator cage and a counterweight, both of which move in opposite directions in the elevator shaft. In this respect, the elevator car and the counterweight run along the guide rails and are supported by at least one support means which is guided on a driving drive pulley. The support means usually consists of one or more sheathed or unsheathed steel cables, one or more synthetic fiber cables, one or more flat belts or profiled belts (such as wedge-ribbed belts) , or corresponding parallel-extending combinations of the above configurations, wherein each individual support means can be guided on a corresponding individual drive pulley or a common drive sha...
