Depending on the application and strength requirements, the line could be a steel cable, a rope, or a cord. This line is stored on the spool which is controlled by the crank.
Some winches require manual cranking while others are powered by electric motors, hydraulics, or gas motors. Regardless of the type of crank, this part of the device controls how much of the line is pulled in or let out and also controls the tension in the line.

Winches are incredibly useful tools and are used in many different applications, ranging from recreational use to industrial purposes. Manually controlled winches are commonly used in sailing to help control sails, and off-road vehicles often use motorized winches to assist in self-towing scenarios. These types of winches are usually fairly small and simple.
However, industrial winches are much larger, stronger, and complex to handle the heavy-duty lifting required in many industrial applications. These winches are controlled by much more powerful motors or hydraulics to handle heavier loads. Industrial-grade winches are used in applications like elevator operation and construction, but they are useful in almost any application that requires heavy-duty hoisting or lifting.
Along with line type and power source, winches can also differ based on their load capacity, diameter, and maximum line speed. These characteristics and features can usually be customized and fit together to meet the specific requirements of a given application.
