At the center is a "slider," a layer of cotton or synthetic (artificial) fabric, which allows the handrail to move smoothly along its track. The next layer,Elevator Supplier known as the tension member, consists of either steel cable or flat steel tape. It provides the handrail with the necessary tensile strength (stretch) and flexibility. On top of the tension member is chemically treated rubber that helps prevent the layers from separating. Finally, the cover is a blend of synthetic plastic and rubber, designed to resist the wear and tear of daily use.
The three inner layers of fabric, steel, and rubber are shaped by skilled workers before being subjected to pressure from machines called presses, which fuse them together. The cover is made by feeding rubber through a computer-controlled extrusion machine, which forces the rubber through a mold to form a continuously shaped piece.
Aside from determining the escalator's style and colors (handrails and side... less
