Intro to Millwright Practice Exam

When a wire rope come-along is overloaded, what typically happens to the load hook?

1. It does not fail

2. It bends without breaking

3. It will fail

4. It becomes easier to remove

The correct answer is: It will fail

When a wire rope come-along is overloaded, the load hook is subjected to forces that exceed its designed capacity. This can result in the failure of the hook, which is often made from high-strength materials that are specifically engineered to handle a certain amount of weight. Overloading compromises the hook’s structural integrity, leading to possible deformation, fracture, or complete failure. Understanding the mechanics of load hooks is essential for millwrights and other tradespeople who work with lifting and rigging equipment. The hook is a critical component that plays a key role in securing and lifting loads safely. Therefore, knowing that failure can occur under overload conditions reinforces the importance of adhering to weight limits specified by manufacturers and utilizing appropriate safety measures when operating lifting equipment. By recognizing that the load hook can fail under overload, practitioners are better equipped to prevent accidents and ensure safe working conditions in their operations.
