Handrail System

Assembly

Moving handrail on each balustrade: a rubber handrail belt driven by friction wheels at step speed, kept taut by a spring tensioner and steered by guide profiles, returning over a newel at each end. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
