Abstract: An elevator guide rail block assembly configured for use with an elevator car or counterweight guide rail is provided. The elevator guide rail block assembly includes a framework and a plurality of rotatable cams attached to the framework. An actuator element is configured to actuate rotation of the plurality of rotatable cams. A clamp structure is attached to the framework and spaced apart from the plurality of rotatable cams. In a rotated orientation, the combination of the plurality of rotatable cams and the clamp structure form a clamping action configured to secure the elevator guide rail block assembly to an elevator car or counterweight guide rail.

Abstract: A wire rope clamp assembly for use with an elevator is provided. The wire rope clamp includes a first clamp member having an outer side and an inner side. The inner side has a plurality of channels configured to receive one or more suspension members. The plurality of first clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. A second clamp member is configured for attachment to the first clamp member. The second clamp member has an outer side and an inner side. The inner side has a plurality of channels configured to receive the one or more suspension members. The plurality of second clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. The plurality of surface structures for the first and second clamp member channels are multidirectional.

Abstract: An elevator traveling cable hanger assembly for use with an elevator is provided. The elevator traveling cable hanger assembly includes a base structure configured for attachment to an elevator hoistway structure. An insert is configured for attachment to the base structure and further configured to support an elevator traveling cable. A plurality of wire rope clips are configured to support a traveling cable core extending from the elevator traveling cable. A plurality of fasteners are configured to secure the base structure, insert, elevator traveling cable and plurality of wire rope clips to the elevator hoistway structure.

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.

Abstract: A break-away canopy assembly configured for use with a work platform in an elevator hoistway is provided. The break-away canopy assembly includes a plurality of spaced apart canopy posts in a substantially vertical orientation. A first support framework is connected to one or more of the spaced apart canopy posts. A second support framework is connected to one or more of the spaced apart canopy posts and opposes the first support framework. The first and second support frameworks each have connected first and second extension assemblies. One or more roof sections span and are connected to the first and second support frameworks. The first and second extension assemblies of the first support framework and the first and second extension assemblies of the second support frameworks are each configured to separate from each other in the event of an uncontrolled descent of the work platform.

Abstract: A false car device configured for use in an elevator hoistway is provided. The false car device includes a platform assembly and a frame assembly configured to support the platform assembly. The frame assembly includes one or more safety assemblies. A lift assembly is configured to facilitate hoisting of the platform and the frame assembly within the elevator hoistway. A climbing rope is attached to the lift assembly and has a tension. The safety assembly is configured to engage an elevator guide rail in the event the tension in the climbing rope is lost.

Abstract: A construction apparatus is provided and span members connected together at a first end by a first connector, the span members having a first end, a second end and a length. Sill brackets are connected to the first end of the span members and are configured to seat against an entrance sill. A second connector connects the span members together at a second end and is configured to seat against a hoistway structure. A plurality of apertures is arranged on the span members and configured to allow a connection to hoist devices. The span members rotate about the sill brackets and the lengths of the span members are longer than a horizontal distance from the entrance sill to the hoistway structure such that when the apparatus is in a seated orientation, the construction apparatus rests in an inclined orientation with respect to a substantially horizontal axis.

Abstract: An elevator counterweight signaling system is provided. The elevator counterweight signaling system includes an actuation assembly configured for contact with an elevator counterweight guide rail. A signaling assembly is configured for electrical communication with the actuation assembly and one or more electrical connectors is configured to electrically connect the actuation assembly with the signaling assembly. The signaling assembly is configured to provide visual and/or audio indications of a moving elevator counterweight assembly.

Abstract: A guide rail straightness tester is provided. The guide rail straightness tester includes a first rail clamp assembly attached to a guide rail. An opposing second rail clamp assembly is attached to the guide rail. A sensor assembly is positioned between the first and second rail clamp assemblies and configured for slidable seating on the guide rail. The sensor assembly includes a sensor plate. A line extends from the first rail clamp assembly through an aperture in the sensor plate and is connected to the second rail clamp assembly. The sensor assembly is configured to determine the straightness of the guide rail during movement of the sensor assembly along the guide rail.
