Parts of an Escalator

Escalators are commonly seen in different establishments. Malls, business center and other commercial buildings have escalators to help people get from one floor to another. It is amazing how these automatic staircases work and it is interesting to find out how every part functions. If you always wonder how escalators work, here are the basic parts that you should know:

Escalators work like the human body. Each component is important to maintain a proper function. An escalator contains escalator handrails, handrail, step, drive, electric motor, guide chain, return wheel and the inner wheel. The terms may be too technical to hear but they actually work as simple as a couple of components pushing and pulling each other to move the stairs.

How It Works

The basic component of the escalator is the series of chains connected together to form gears. This is then being moved by a motor which works via an electrical source. This electric motor is the power house of the escalator so each of the component can work efficiently. The electric motor is just like the human heart that sends electrical impulses all over the body. The typical electric output of the electric motor is about 100 horsepower. That is 100 times greater than a regular air conditioning unit.

The escalator handrails works by moving people and items from one floor to the other. The angled movement is due to the chain loops that move series of steps to go upwards and downwards while keeping a steady level. At the end of the escalator, the steps collapse in order to achieve a flat platform. The flat platform is important so anyone can step and get out of it safely and easily.

Now, the every step is composed of two wheels. The upper wheels are connected to the chains and pulled at the top of the escalator. The other wheel glides in the track. This will allow a smooth movement while the elevator goes up or down. To better provide a safe ride, the escalator handrail is installed. This is where people hold on to as the elevator works. The hand rails are also moved by the electric motor so it can move in the same way with the steps. In order to provide a non-slip grip, the escalator handrails are made out of rubber.

It is good to know that the escalator cannot be used to transport heavy items. While it is good to carry multiple people and items, its capacity always have a weight limit. This is due to the escalator’s loading rate. In case you want to transport heavier items, it is best to check out the capacity of the escalator. There are cases where an elevator is more efficient in transporting heavy items.

These are the basic parts of an escalator. It is truly a great staircase where people can conveniently transfer from one floor to another.
