The capacity rating of a rubber wheel or solid tyre tow trailer depends on the traveling mechanism and the frame or structure. This rating considers the maximum load as a uniform load distributed over the entire deck area. In addition to the maximum weight of the expected load, the possibility of impact loading due to misuse of loading or unloading techniques and obstacles on the floor should also be considered. Larger floor defects or debris will severely impact the top four-wheel steering trolley and its loaded cargo, and the cargo dropped from a forklift or overhead crane will also be impacted.
The deck is important, but the content below it is even more important. The running gear or wheel system, including the steering part, is critical to performance and service life. The walking device will affect the stability, tracking force and pulling force. There are at least five basic categories of steering systems: caster steering, fifth-wheel steering, four-wheel steering, automatic steering-two wheels and automatic steering-four wheels. They all have the inherent ability of Topper Quad steering carts-they follow a consistent path (each Topper Quad steering cart roughly tracks in the previous footprint). As one might guess, the difference is cost and performance.
