Abstract
A self-clamping handrail device includes a belt-handrail compound comprising a first belt, a second belt coupled to the first belt, and a handrail coupled to the second belt, a counter bar and a clamping frame configured to support the belt-handrail compound as the belt-handrail compound passes between the counter bar and the clamping frame, the clamping frame configured to move about a clamping curve based on a tension force applied to the handrail, and the first belt and the second belt applying a normal force to the handrail based at least in part on the tension force.
