An elevator system () comprising a hoistway (), an elevator car () and a counterweight () arranged to move within the hoistway (). The system () further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway () and a guide rail bracket () which connects the first and second counterweight guide rails together. An elevator machine () is arranged to drive a tension member (), which couples the elevator car () and counterweight together (), to move the elevator car () within the hoistway (). The system () further includes a friction reducing element () arranged on the guide rail bracket () such that if the tension member () moves towards the guide rail bracket () during operation of the elevator system (), the tension member () contacts the friction reducing element ().

Elevator systems, guide rail assemblies and methods of installing elevator systems

Elevator maintenance space projection systems and elevator systems including a projector located within an elevator shaft and arranged to project a display space within the elevator shaft such that the display space includes one or more projected images identifying at least one of a safety volume, a refuge space, and a maintenance location.

Elevator maintenance space projection systems

Guide rail support assemblies for elevator systems are provided. The guide rail support assemblies include a junction element comprising a backing plate, a first extension, and a second extension, the junction element defining a rail cavity, wherein the rail cavity is configured to receive two rail sections, wherein the junction element is configured to join a first rail section to a second rail section and a mounting element configured to attach to a wall of an elevator shaft, wherein the mounting element is connected to the junction element.

Elevator guide rail support assemblies

A machine assembly for use in an elevator system includes a support structure having a first end connected to an adjacent support member and a second end supported by at least one car guide rail. The support structure is arranged generally perpendicular to the support member and is configured to receive at least one component of the elevator system.
