Why use casters such as Iron Caster Side Brake? Let's take a look at it with Xiaobian!
The invention of the wheel is no less than the four inventions of China. When the wheel has not evolved into the current caster, the use of the wheel is quite common. At first it was just to save energy and to facilitate the movement of heavy objects. As the human development continued, the requirements for the wheels increased. Later, from the wheels to the casters of today, it such as PU Caster Side Brake can be used more conveniently and conveniently.
Since people invented the wheel, it has become much easier to carry and move objects, but the wheels can only run in a straight line. It is still very difficult to change the direction when carrying a large object. Later, people invented the steering structure. The wheels, which we now call the activity wheel (the universal wheel), are collectively called the "casters." The emergence of casters such as Heavy Duty Casters With Brakes has brought an epoch-making revolution to people's handling, especially moving objects, which can be easily transported and moved in any direction, greatly improving efficiency.
