An escalator is a moving staircase used to transport people between different floors or levels of a building. It is commonly installed in shopping malls, airports, metro stations, departmental stores, and other public buildings where large volumes of pedestrian traffic need to be managed efficiently. Escalators are designed to provide continuous movement of people, reducing waiting time and improving convenience compared to fixed staircases or elevators. In modern building design and maintenance planning, escalators are considered an important component of vertical transportation systems. The basic structure of an escalator consists of a motor-driven chain of steps that move in a continuous loop. Each step has a pair of wheels attached to it, which run on tracks located inside the escalator structure. The steps remain horizontal while moving, ensuring passenger safety and comfort. The escalator system also includes handrails that move at the same speed as the steps, providing balance and support to passengers while they are riding. The main components of an escalator include steps, truss, motor, drive system, landing platforms, handrails, and control systems. The truss is the metal framework that supports the entire escalator structure. It is usually made of _________ _____ _________ _______ _________.
