1. Caster impact load: The momentary load-bearing capacity of the caster when the equipment is impacted or shaken by the load.
2. Travelling load on casters: the load-bearing capacity of the steering casters when moving. Also called dynamic load. The dynamic load of the steering caster is different due to the implementation of the specification and the test method of the factory. It is also different due to the different information of the wheel. The key is whether the structure and quality of the bracket can resist impact and shock.
3. Caster turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. Proper spacing enables the steering casters to turn 360 degrees. Whether the turning radius is reasonable or not directly affects the service life of the steering casters.
4. The structure of steering casters is used to install under the equipment to make it move freely. The steering casters are mainly divided into two categories:
(1) Casters that can only move in a straight line are called fixed steering casters.
(2) You can drive in any direction at will. The 360-degree steering bracket is equipped with a single wheel, which is called a movable steering caster.
5. Caster bracket steering center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.
6. Travelling flexibility on casters:
(1) On a stable ground, the factors that affect the flexibility of the steering casters are: the structure of the bracket and the selection of the bracket steel, the size of the wheel, the wheel type, and the bearing. The larger the wheels, the better the driving flexibility. Hard, narrow wheels require less effort than flat-edged, soft wheels.
(2) But on uneven ground, soft wheels can better maintain the equipment and absorb shocks.
