Why use castor?
Why use castor? Follow the below small make up look together! The invention of the wheel as China's four great inventions, the wheels have not evolved into a now trundle, the use of the wheel is also quite common. At first, it is only in order to save energy and convenient and the weight of the mobile, with the continuous development of human is increasing on the requirements of the wheel, and then from castor wheels change into now, it can better and more convenient use. Since people invented the wheel, moving and moving object is a lot easier, but can only be run on a straight line, wheel for moving heavy objects to the direction of the change is still very difficult, the people then invented with a steering wheel structure, which is what we now call the activities of the wheel ( Universal wheel) , called 'caster'. The emergence of the castor to people's handling brought epoch-making revolution especially the moving object, not only can easily carry, can also with any direction, greatly improving the efficiency. The existence of the castor castor brings great convenience to people's life, we all know that the wheels can reduce the load people, carrying more convenient to get, but ordinary wheels can only forward or backward movement if a change of direction is more troublesome, but now the diversity of castor features to perfect the problem solved. Castor also is what we call the universal wheel, its structure is allowed to rotate 360 degrees; Fixed castor also called directional casters, it has no rotating structure, can't turn. Usually two casters are generally use collocation, such as the structure of the trolley is in front of two directional wheel, behind near the armrest is driven by two wheels. With the continuous development of modern science and technology, caster has been involved in all walks of life, according to the needs of different industries, continuously invented all kinds of casters to adapt to the current conditions, so castor became indispensable components, the development of the castor also became a special industry.
