  • False car device
    Patent number: 10988346
    Abstract: An installation gauge for use in an elevator hoistway is provided. The installation gauge includes a platform assembly and a frame assembly configured to support the platform assembly. The frame assembly includes one or more safety assemblies and one or more guide assemblies. Opposing guide shoes are connected to each of the one or more guide assemblies. The opposing guide shoes are centered about a guide rail and configured to determine a centerline of the guide rail. A lift assembly is configured to facilitate hoisting of the platform assembly and the frame assembly within the elevator hoistway. A plurality of safety ropes couples the lift assembly to the one or more safety assemblies. A climbing rope is attached to the lift assembly. The determination of the centerline of the guide rail can be used as a basis to install other hoistway equipment.
