A come along, also known as a cable puller or a Tirfor, is a mechanical device used to pull or lift heavy objects. It consists of a ratcheting mechanism that engages with a wire rope or chain, allowing the user to apply force in short, controlled increments. Come alongs are commonly used in construction, rigging, and other applications where heavy objects need to be moved or positioned.
Come alongs offer several advantages over other methods of pulling or lifting. First, they are relatively lightweight and portable, making them easy to transport and use in tight spaces. Second, they provide a high degree of mechanical advantage, allowing the user to move heavy objects with minimal effort. Third, come alongs are self-locking, which means that they will not slip or release the load once it has been engaged.
