The steps of the early Escalator Supplier were made of wood. Since the spiral escalator was fired at the Underground Railway Station in London in 1987, most of the wooden steps still used have been changed to metal. The steps of modern escalators are made of metal, and below each step is a triangular bracket. There are two high and low shafts at the bottom of the bracket, and there are wheels on the shaft. The two wheels on each side walk on different tracks, and the steps are kept level by changing the distance between the tracks. The wheels above each step support are connected by hinges. A motor is installed under the comb plate at the top of the escalator to drive the hinge to move the steps. When the steps reach the end of the escalator, they will first turn into a horizontal row for passengers to leave, then pass through the comb board, then turn to the bottom, and walk in the other direction, forming an endless circle. The side panels of some new escalators are made of glass, so this mechanical structure can be clearly seen. As for the handrails on both sides, they are made of rubber and driven by wheels, and the speed must be consistent with the steps.
Most of the escalators are straight. In 1985, Japan's Mitsubishi Electric invented the curved, spiral-shaped escalator for the first time. In addition to saving space, the spiral escalator is also very artistic. In addition, some escalators can be turned back to level in the middle section. This can reduce passengers' fear of height when using very long escalators, and it can also be more flexible with the building.
When many people use escalators, in addition to letting the escalator drive, they also use their legs to walk on the steps to save time. Therefore, when using an escalator, the standing passengers should lean on the same side of the step and let out the other side of the step for people walking. However, different regions have different conventions about which side you should stand on. For example, the London Underground Railway, the Washington Underground Railway, the Kansai Railway in Japan, and the Taipei MRT require standing passengers to stand to the right; but Tokyo, Japan requires passengers to stand on the left. The Montreal subway has no rules, because they believe that passengers should not walk on escalators at all.
When using an escalator, you should also be careful to hold the handrails tightly, do not stand on the edge of the step, do not stick your head or hands out of the ladder, otherwise you may hit the ceiling or adjacent escalators, do not run and play, do not use the escalator to carry goods. Strollers, cargo carts, etc. should use elevators. Passengers who use wheels or crutches should use elevator supplier as much as possible. Escalators will have emergency stop buttons for use in accidents.
