Overhead Crane Practice Test

Which item listed below must be marked on all overhead cranes?

1. Manufacturer name

2. Maximum capacity

3. Rated capacity

4. Model of crane

The correct answer is: Rated capacity

The rated capacity is essential information that must be marked on all overhead cranes because it indicates the maximum load that the crane can safely lift without risking failure or compromising safety. This marking is crucial for operators and maintenance personnel as it ensures that the crane is used within its designated limits, reducing the risk of accidents and ensuring compliance with safety regulations. The rated capacity helps prevent overloading, which can lead to structural failure, tipping, or other dangerous situations. Ensuring that this information is clearly visible is a fundamental practice in maintaining a safe working environment when using overhead cranes. While the manufacturer name, maximum capacity, and model of crane are also important for identification and compliance, the rated capacity specifically relates to the operational safety of the crane, making it a critical marking that must be present.
