Rhode Island Hoisting License Practice Test

Question: 1 / 400

Should the loader arm service lock be installed when operating the backhoe?

Yes, it should always be installed

No, it should not be installed during operation

The statement that the loader arm service lock should not be installed during operation is correct because the service lock is designed to prevent movement when the machine is not in use or during maintenance tasks. When a backhoe is in operation, the loader arm must be free to move and operate effectively for the tasks at hand, such as digging or lifting. Installing the service lock while operating the machine can hinder the operator’s control and lead to potential accidents.

Maintaining flexibility and full functionality of the loader arm during operation is crucial for safe and efficient operation. Additionally, recognizing that the use of safety devices like service locks is intended for specific situations—such as maintenance or transport—reinforces the importance of understanding their purpose and appropriate application in different contexts.
