Escalator, a moving escalator used to transport between floors or levels in subways, buildings, and other communal pedestrian areas.
Jesse W. of the United States in 1891. The tilt belt, invented by Renault, provided a means of transportation for passengers aboard the belt-mounted clit, tilted at a 25-degree angle; The fender was fixed, but an improved version with a running fender was launched the same year.
An escalator named Escalator, shown at the 1900 Paris Exposition, was first applied. Originally a trademark of Otis Elevator Company, the term was judged in 1949 to become a universal domain through general use.
Modern escalators typically tilt at 30 and are confined to a height of about 60 feet (18 m), with a floor height of about 12 feet (3.5 m) above the ground. It is electrically driven, driven by a chain and sprocket, and held in a suitable plane by two tracks. As the foot approaches the landing, it passes through a combing device; The Yao switch is activated to turn off the power if an object gets stuck between the tread and the comb.
The escalator moves at 120 feet (36 meters) per minute; The larger ones accommodate 6000 passengers per hour. When the chain breaks, the escalator closes when the tension is released. The safety switch stops the device if the handrail breaks or becomes loose or the side plate deviates.
Moving ramps or sidewalks, sometimes called escalators, are special types of escalators designed to move people and objects horizontally or along a slight bend. Slopes can have either stiff or pronounced footsteps or an unbroken belt. Ramps can go up to any angle up to 15 degrees; After this ramp, the ramp becomes very steep and escalators are preferred.
