What is the role of casters in life?

Casters are used to wonderful effect in everyday life, and it is no exaggeration to say that without them, our life would be a mess.



The invention of the caster is no less than the four great inventions of China. Before the wheel evolved into the present foundry, the use of the wheel has been throughout the whole time. At first, it was just to save energy and facilitate the movement of heavy objects. With the continuous development of human beings, the requirements for wheels are getting higher and higher. Later, the wheels became the casters, which can be more convenient for us to use.



The existence of casters brings great convenience to people's life. We all know that wheels can reduce people's weight and make it easier to take them, but generally wheels can only move forward or backward, if changing the direction is more difficult, and now the diverse features of casters make this problem solved.



Movable casters are what we call universal wheels, whose structure allows 360 degrees of rotation; Fixed casters also called directional casters, its structure does not rotate, cannot rotate. Usually two kinds of casters are generally used together, for example, the front structure is two directional wheels, the rear propeller close to the handrail is two universal wheels.

In a word,casters have a great enfluence on our practical life.
