Abstract
An elevator system that can check a function of detecting derailment of an elevating body without disconnecting the elevating body from a guide rail. The elevator system includes a conductive wire that is provided along a guide rail, a contact that is attached to the elevating body, and is configured to come into contact with the conductive wire in the case where the elevating body is disconnected from the guide rail, a control panel that is configured to detect electrical conduction between the conductive wire and the contact, and an inspection contact that is attached to a preset position of the conductive wire, and is disposed at a position that allows the inspection contact to come into contact with the contact in the case where the contact moves to the preset position.
Claims5
An elevator system comprising:
- a conductive wire provided along a guide rail for guiding movement of an elevating body of an elevator;
- a contact having conductivity, the contact being attached to the elevating body and configured to come into contact with the conductive wire in a case where the elevating body is disconnected from the guide rail;
- a control panel electrically connected to the conductive wire and configured to detect electrical conduction between the conductive wire and the contact;
- and
- an electrically conductive inspection contact being directly attached to and in contact with the conductive wire at a preset position on the conductive wire,
- wherein the electrically conductive inspection contact is disposed at a position that allows the electrically conductive inspection contact to come into contact with the contact in response to the contact moving to the preset position.
