National Commission for the Certification of Crane Operators (NCCCO) Mobile Crane Practice Exam

When is a crane allowed to be overloaded?

1. During test operations

2. When lifting a non-structural load

3. Never

4. When conditions require

The correct answer is: Never

A crane is never allowed to be overloaded because doing so can severely compromise safety and increase the risk of accidents. Overloading a crane exceeds its designed lifting capacity, which can lead to mechanical failure, tipping over, or other dangerous situations. Every crane has a specific load rating that is determined by various factors, including its design, stability, and operating conditions. This rating is established to ensure safe operations under intended conditions. Operating beyond this capacity not only endangers personnel but can also damage the crane itself. In practice, adhering strictly to load limits is crucial for maintaining not just safety but also compliance with regulatory standards and guidelines. Therefore, it’s vital for crane operators and all personnel involved to understand that exceeding load limits is never permissible.
