Mainly in trolleys, mobile scaffolding, workshop trucks and so on very widely.
The simplest inventions are often the most important, and casters are exactly that. At the same time, the level of development of a city is often positively correlated with the use of casters. Cities such as Shanghai, Beijing, Tianjin, Chongqing, Wuxi, Chengdu, Xi'an, Wuhan, Guangzhou, Foshan, Dongguan, Shenzhen and other cities have a very high caster usage rate.
Casters are constructed from a single wheel mounted on a stand that fits under the equipment to allow it to move freely. Casters are mainly divided into two categories:
A. Fixed casters: The fixed bracket is equipped with a single wheel, which can only move in a straight line.
B. Active casters: The 360-degree steering bracket is equipped with a single wheel, which can drive in any direction at will.
There are many types of single wheels of casters, which vary in size, model, tire tread, etc. Choosing the right wheel is based on the following conditions:
A. Use the site environment.
B. Product load capacity.
C. The working environment contains chemicals, blood, grease, oil, salt and other substances.
D. Various special climates, such as humidity, high temperature or severe cold
E-resistance to shocks, collisions and quiet ride requirements.
