A small hand-cranked winch, also known as a mini hand-cranked winch, is a manual lifting tool. It is characterized by its compact size and low weight, and it is designed for light-duty lifting, pulling, and tightening tasks in tight spaces or in environments where no power source is available. · Size and portability: The mini version can be held in one hand; its weight is very low – for example, a model with a capacity of 250 kg weighs only about 2 kg. · Common rated capacities: The most common specifications available are 0.25 tons, 0.5 tons, and 0.75 tons, though there are also models with capacities of 1.5 tons or even more. · Standard lifting heights: These are typically 1 meter, 1.5 meters, 2.5 meters, etc.; the length of the chain can also be customized according to requirements. · Working principle: By manually turning the handle, leverage is used to generate pulling force, which in turn moves the internal clamps or chain mechanism, allowing the heavy object to be lifted or moved.
