käsikurviga

Käsikurviga is an Estonian term that translates to "with a hand-wheel" or "hand-cranked" in English. It refers to a mechanism or device that is operated manually using a wheel or handle that is turned by hand. This type of operation is common in a variety of applications where precise control or a slower, more deliberate adjustment is required, or where electric or automated power is not available or practical.

Historically, many machines and tools were hand-cranked. Examples include early types of winches, drills, coffee grinders, and some agricultural equipment. The term emphasizes the direct physical interaction between the operator and the machine's control mechanism. In modern contexts, "käsikurviga" might describe anything from a manual valve on plumbing to a specific type of adjustable furniture or a component within a larger, non-powered system. The core idea is that a hand-turned wheel is the primary means of actuation. This method allows for a high degree of tactile feedback and fine-tuning of position or speed.
