Which tool is a hand-operated winch?

The come along is a hand-operated winch that utilizes a ratcheting mechanism to pull heavy loads. It typically consists of a frame, a ratchet lever, and a cable or chain connected to a hook or another securing device. Using a come along allows firefighters and other professionals to safely and efficiently move heavy objects, such as vehicles or debris, in various situations. This tool is particularly useful in rescue operations or scenarios where a powered winch is impractical or unavailable.

Other tools mentioned, such as the rabbit tool, block-and-tackle, and porto-power, serve different functions. For example, a block-and-tackle is a rigging setup that includes multiple pulleys and is used for lifting or pulling heavy loads by distributing weight, but it is not strictly classified as a hand-operated winch in the way a come along is. The rabbit tool is primarily used in forcible entry situations, and the porto-power is a hydraulic tool used to apply force, neither of which fits the definition of a hand-operated winch.
