Abstract (en)
[origin: US2013153340A1] An elevator installation includes a cage, a counterweight, a drive and at least one support element. The cage and the counterweight are supported by the support element, which is driven by the drive to move the cage and the counterweight in opposite directions. The support element includes at least one test element, wherein the test element is contacted by at least one contacting device and connected with a measuring device so that an electrical resistance of the test element is determinable by the measuring device, wherein the electrical resistance of the test element changes due to stretching of the test element so that through measurement of the electrical resistance of the test element at least one of the following states of the elevator installation is ascertainable: loading of the cage, a slack support element, a tension difference between at least two support elements and damage of the support element.
