Installation height: refers to the vertical distance from the ground to the installation position of the equipment. The installation height of the caster refers to the maximum vertical distance from the floor of the caster and the side of the wheel.
Bracket steering center distance: refers to the horizontal distance from the center rivet vertical line to the center of the wheel core.
Rotation radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The proper spacing allows the caster to make 360-degree steering. The reasonableness of the radius of rotation directly affects the service life of the casters.
Driving load: The load-bearing capacity of the casters is also called the dynamic load. The dynamic load of the casters varies depending on the test method of the factory. It also varies with the materials of the wheels. The key is whether the structure and quality of the brackets can resist impact and Shock.
Impact load: The instantaneous load-bearing capacity of the caster when the equipment is impacted or vibrated by the load. Static load Static load Static load Static load: The weight that the caster can withstand at rest. The static load should be 5 to 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 turn than soft, wide wheels. The radius of rotation is an important parameter for the rotation of the wheel. Too short a radius of rotation increases the difficulty of steering. If it is too large, it will cause the wheel to sway and shorten its life.
Driving flexibility: Factors affecting the flexibility of the caster include the structure of the bracket and the selection of the bracket steel, the size of the wheel, the type of the wheel, the bearing, etc. The greater the wheel, the better the driving flexibility, and the harder and narrower on the stable ground. The wheels are less laborious than the soft wheels on the flat side, but the soft wheels on the uneven ground save effort, but the soft wheels on the uneven ground can better protect the equipment and shock absorbers!
