Casters are a general term, including movable casters, fixed casters and movable brake casters. Movable casters are also what we call universal wheels, and its structure allows 360 degrees of rotation; Fixed casters are also called directional casters, which have no rotating structure and cannot be rotated. Usually two kinds of casters are generally used with each other, such as the structure of the trolley is two directional wheels in the front side, and two universal wheels close to the push handrail in the back. There are many kinds of casters, such as pp casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters and so on.
One、The origin and development of casters
To trace the history of casters is also a very difficult thing, but after people invented the wheel, carrying and moving objects became much easier, but the wheel can only run in a straight line, for the handling of major objects when the change of direction is still very difficult, then people invented a wheel with a steering structure, that is, we call the caster or universal wheel. The appearance of casters has brought an epoch-making revolution to people's handling, especially moving objects, which can not only be easily handled, but also move in any direction, greatly improving efficiency.
In modern times, with the rise of the industrial revolution, more and more equipment needs to be moved, and casters are more and more widely used in the world, and all walks of life are almost inseparable from casters. In modern times, with the continuous development of science and technology, equipment is more and more versatile and high utilization, and casters have become indispensable components. The development of casters has become more specialized and has become a special industry.
Two、Applications of casters
Logistics transport: In the logistics industry, casters are an indispensable accessory. Whether it is shelves, pallets or various transportation tools, it is inseparable from the support of casters. It allows items to be easily moved between warehouses and transport vehicles, greatly improving logistics efficiency.
Medical equipment: In the medical field, many devices need to be equipped with casters so that they can be easily moved. For example, hospital beds, examination tables, medical carts, etc., all rely on casters to achieve fast and convenient movement.
Office furniture: In the office, many furniture such as desks, filing cabinets, lockers, etc., are equipped with casters. This allows employees to easily adjust the position of furniture and improve work efficiency.
Leisure and entertainment: In shopping centers, exhibition halls and other leisure and entertainment places, many display shelves, display stands, etc., are equipped with casters. This allows display items to be moved and arranged easily, providing customers with a better shopping experience.
Three、The advantages and value of casters
Convenience: Casters make it easy to move items between locations without relying on other tools or manpower. This greatly improves work efficiency and convenience.
Flexibility: The casters are designed so that items can be easily turned and adjusted for a variety of different working environments and needs.
Space saving: By using casters, items can be pushed into corners or storage Spaces, saving space and making the work environment cleaner and more orderly.
Improved safety: In certain high-risk situations, such as medical operating rooms or industrial workshops, the use of casters can reduce the risk of accidental sliding of items and improve safety.
Economic benefits: Through the use of casters, enterprises can reduce labor costs and time costs, improve work efficiency and economic benefits.
