A trolley is a transport vehicle pushed and pulled by manpower. It is the ancestor of all vehicles. Although the trolley material handling technology continues to develop, the trolley is still used as an indispensable transport tool.
The trolley has been widely used in production and life because of its low cost, simple maintenance, convenient operation, light weight, and it can work in places where motor vehicles are inconvenient to use, and it is very convenient to carry lighter objects in short distances.
Trolleys are divided into one-wheel, two-wheel, three-wheel and four-wheel. The wheelbarrow can travel on narrow springboards, temporary bridges and small intestines, and it can turn on the spot, making it very convenient to dump cargo.
Commonly used two-wheeled vehicles include hand-push trucks (also known as tiger trucks), rack trucks, and bucket trucks that carry bulk materials. There is one of the three-wheeled trolleys and two of the four-wheeled trolleys that can rotate around a vertical axis. This kind of swivel caster can automatically adjust to the direction of least running resistance as the direction of vehicle movement changes during operation.
