Käsislingi

Käsislingi is an Estonian term that translates to "hand sling" or "hand hoist." It refers to a simple mechanical device used for lifting or pulling loads. These devices typically consist of a rope or chain wound around a central drum or axle, which is operated by a hand crank.

The primary function of a käsislingi is to provide mechanical advantage, allowing a user to lift objects that would otherwise be too heavy to move manually. By turning the crank, the rope or chain is wound onto the drum, shortening its length and thus pulling the attached load upwards or towards the user. The gear ratio of the crank mechanism determines the amount of force multiplication.

Käsislingid are often used in various practical applications where heavy lifting or pulling is required but sophisticated machinery is not available or necessary. This can include construction sites for moving materials, workshops for lifting engines or heavy equipment, or even in agricultural settings. Their simplicity, portability, and relatively low cost make them a versatile tool.

Variations of the käsislingi exist, differing in size, load capacity, and the type of rope or chain used. Some may be permanently mounted, while others are designed to be portable. The design prioritizes ease of operation and durability for manual labor.
