The material of the sheave wheel is one of the most important factors in determining the ultimate load. Sheave wheels are typically made of metal, such as steel or aluminum, but they can also be made of other materials, such as plastic or composite materials. Metal sheave wheels are generally stronger than plastic or composite sheave wheels, but they are also heavier.
The size of the sheave wheel is also a factor in determining the ultimate load. Larger sheave wheels can handle more load than smaller sheave wheels. This is because larger sheave wheels have a larger surface area, which distributes the load over a greater area.
The design of the sheave wheel is also a factor in determining the ultimate load. Sheave wheels with a larger groove radius can handle more load than sheave wheels with a smaller groove radius. This is because the larger groove radius provides more support for the rope or cable that is running over the sheave wheel.
The ultimate load of a sheave wheel is an important factor to consider when selecting a sheave wheel for a particular application. The sheave wheel must be able to handle the maximum load that will be applied to it, or it could fail, which could cause serious damage or injury.
