Embodiment Construction

[0034] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0035] figure 1 An elevator including an elevator testing system for testing an elevator after an earthquake is shown in one embodiment of the invention.

[0036] exist figure 1 In , an elevator 100 is shown. An elevator 100 runs in an elevator shaft 102 . The elevator shaft 102 includes a guide rail 104 for an elevator car 110 and a guide rail 106 for a counterweight 180 . Guide rails 104 enable elevator car 110 to move vertically in a controlled horizontal position relative to walls in elevator shaft 102 and landing doors in the elevator shaft. Similarly, rails 106 enable counterweight 180 to move vertically in a controlled horizontal position. For example, the elevator car 110 or the counterweight 180 do not collide with the walls of the elevator shaft 102 . The elevator car 110 is suspended on a plurality of parallel hoisting ...

Abstract

The invention relates to a method and an apparatus for automatic condition checking of an elevator, wherein an elevator car (110) of the elevator is situated in a door zone of a first landing (122) inan elevator shaft (102) following an earthquake. The method comprising determining whether the load carried by hoisting ropes (134) is evenly distributed between the hoisting ropes by checking the status or measurement data of at least one rope tension measurement device (136). The test unit (150) determines whether the elevator car (110) is empty and conducts a drive test for the elevator car inorder to determine unimpeded access for the elevator car to other landings (121, 123). The elevator is returned to normal use, if the drive test indicates unimpeded access for the elevator car to theother landings.

Description

technical field [0001] The invention relates to elevators, elevator maintenance, elevator state inspection and methods for automatic elevator state inspection. Background technique [0002] Today, there is a large installed base of elevators in seismically active geographic areas. Elevators in seismically active areas exhibit maintenance problems. To ensure that any damage an earthquake may cause to the elevators is not a threat to passengers, the elevators are equipped with earthquake detection equipment. Earthquake detection equipment determines whether the magnitude of a seismic event, such as an earthquake, exceeds a predetermined threshold. If the threshold is exceeded, at least one elevator associated with the earthquake detection device is taken out of service. Elevators that were out of service due to the seismic event could only be brought back into service after maintenance personnel performed a manual reset. Before resetting, maintenance personnel must visuall...
