Caster wheel configurations
How many swivel and fixed casters are used on one unit directly affects turning radius, straight-line stability, rolling resistance and load distribution. Configuration advice must be confirmed together with equipment size, center of gravity and route.
| Configuration | Common effect | Risk or to be confirmed |
|---|---|---|
| Four swivel casters | Flexible steering, suitable for limited-space applications. | Straight-line stability and brake requirements to be confirmed. |
| Two swivel casters + two fixed casters | More stable straight-line movement, often used for trolley equipment. | Turning space, pushing direction and floor to be confirmed. |
| Centered fixed-caster configuration | Can improve turning of some long equipment. | Load distribution, center height and rocking risk to be confirmed. |
| Special wheel configuration | Used for AGV, rail, container or custom equipment. | Must be confirmed by drawings, samples and tests. |
