An introduction to and maintenance tips regarding this important safety/comfort system
The handrail movement mechanism of an escalator consists of a complex structure, which has its own characteristics from other parts of the system. Major manufacturers produce handrails in two shapes: “C” and “V.” The inside of “C” is smooth, requires little friction and is driven by a wheel with a layer of compressed rubber on it. As for “V,” there is a tab inside that concentrates the friction force in the middle of the handrail. The tab is moved by a wheel that travels in a groove in the middle of the handrail.
