Overhead Crane Practice Test

What action should an operator take in case of a power loss?

1. Leave the crane in motion

2. Put controllers in the off position

3. Continue operating until power is restored

4. Lower the load and secure it

The correct answer is: Put controllers in the off position

In the event of a power loss, the operator should put the controllers in the off position to ensure safety. This action prevents accidental movements of the crane and its load, which could lead to dangerous situations if the power were to return unexpectedly. Ensuring that the controls are off puts the crane in a state where it cannot be inadvertently activated, providing a safer environment for all personnel in the vicinity. While securing a load and lowering it is a critical safety procedure, it cannot be done if the crane is in motion or if the operator loses control due to power failure. Simply leaving the crane in motion could result in uncontrolled movements, making the situation hazardous. Therefore, deactivating the controllers is the most immediate and prudent action to take, establishing a controlled and safe condition until the power is restored or assistance is available.
