Escalators are a type of transportation device designed to transport people between different levels in a building. They consist of a series of moving steps on a 30-35° incline that are attached to a closed circuit driven by an electric motor with a mechanical reducer or linear gear.
These transport vehicles are known for their smooth operation, low noise levels, durability, ease of maintenance, and attractive design. They offer a safe, comfortable, and reliable means of transportation for people navigating different heights in areas with high foot traffic, such as shopping malls, supermarkets, and airports.
