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.
