What is rated capacity?

• A. The maximum weight a crane can lift
• B. The maximum allowable load at a given radius
• C. The total weight of the crane
• D. The weight of the crane's components

Answer: (B)

Rated capacity refers to the maximum allowable load a crane can lift at a specific radius. This is crucial for safe crane operation, as the crane's lifting ability varies depending on factors such as the load's distance from the crane's center of rotation and the configuration of the crane itself. The rated capacity ensures that operators understand not only the maximum weight a crane can lift but also the conditions under which it can safely lift those weights. Understanding rated capacity is essential for maintaining the integrity of the crane and ensuring the safety of the operation. It encompasses the considerations of leverage and stability, which vary with the position of the load. Therefore, knowing the rated capacity at a given radius allows for safe and efficient lifting practices.
