a portable mechanical device used for pulling, tensioning, or lifting heavy loads
A come-along is a manual tool used to pull or lift heavy objects by applying tension. It consists of a gear mechanism, a chain or cable, and hooks at both ends. By operating the handle, the user can slowly pull or lift the load, usually a little at a time, until it reaches the desired position. Come-alongs are commonly used in construction, automotive repair, or moving heavy equipment, as they allow precise control over the movement of large or bulky items. They are compact, portable, and effective for lifting or dragging objects in tight spaces.
