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.
