Structural features
Installation height: refers to the vertical distance from the ground to the installation location of the equipment, and the installation height of the caster refers to the maximum vertical distance from the bottom of the caster and the edge of the wheel.
Bracket turning center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.
Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The proper spacing enables the casters to make a 360-degree turn. Whether the turning radius is reasonable or not directly affects the service life of the casters.
Driving load: The load-bearing capacity of the casters when they are moving is also called dynamic load. The dynamic load of the casters is different due to the different test methods in the factory and the material of the wheels. The key is whether the structure and quality of the bracket can resist impact and Shock.
Impact load: the instantaneous load-bearing capacity of the caster when the equipment is impacted or shaken by the load. Static load Static load Static load Static load: The weight that the caster can bear in a static state. The static load should generally be 5-6 times the exercise load (dynamic load), and the static load should be at least 2 times the impact load.
Steering: Hard, narrow wheels are easier to steer than soft, wide wheels. The turning radius is an important parameter for wheel rotation. Too short a turning radius will increase the difficulty of steering, and too large a turning radius will cause the wheel to shake and shorten the life.
Driving flexibility: The factors that affect the driving flexibility of the casters include the structure of the bracket and the selection of bracket steel, the size of the wheel, the type of wheel, and the bearing. The larger the wheel, the better the driving flexibility. It is hard and narrow on a stable ground. The wheels are less labor-intensive than flat-sided soft wheels, but on uneven ground, soft wheels are less labor-intensive, but on uneven ground, soft wheels can better protect the equipment and absorb shock!
Application field:
Mainly in the trolley, mobile scaffolding, workshop trucks, etc. extremely widely.
The simplest invention is often the most important, and casters have this characteristic. At the same time, the degree of development of a city is often positively correlated with how many casters are used. Cities like Shanghai, Beijing, Tianjin, Chongqing, Wuxi, Chengdu, Xi'an, Wuhan, Guangzhou, Foshan, Dongguan, Shenzhen and other cities have very high casters.
The structure of the caster is made up of a single wheel mounted on the bracket, which is used to install under the equipment to make it 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. Movable 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 caster wheels, which are different in size, model, and tire surface.
Choosing the right wheel is based on the following conditions:
A. Use site environment.
B. The carrying capacity of the product.
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. Requirements for shock resistance, collision and driving quietness.
