Question: 1 / 400

What is the function of a thimble in a towing system?

To secure the vehicle

To act as a pulley

To protect the cable at the hook assembly

The function of a thimble in a towing system primarily revolves around protecting the cable at the hook assembly. A thimble is a small, usually metal, fitting that is used to provide a smooth surface around which the towing cable or rope can bend. This helps prevent wear and tear on the cable, especially at critical points where the cable is looped or terminated, such as where it connects to the hook assembly. By maintaining the shape of the loop and distributing the load more evenly, the thimble helps prolong the life of the cable and ensures that it functions effectively during towing operations.

Having this protective feature is essential for both safety and efficiency, as frayed or damaged cables can lead to towing failures and potentially dangerous situations on the road. The other functions mentioned, while important in towing, do not specifically capture the primary purpose of a thimble.
