Gravitationsdrevne

Gravitationsdrevne describes systems or processes that are powered primarily by gravity. In such systems, gravitational potential energy is converted into kinetic energy as a body descends or moves along a downward slope, providing the driving force without relying on external motors or pumps. The concept is widely used in engineering and physics to exploit height differences or masses suspended by cables or guides.

Typical configurations include gravity-fed water supply, where water flows from a higher reservoir to lower-demand points, gravity conveyors and chutes that transport materials along a track by their own weight, and counterweight-based mechanisms such as elevators and certain types of cranes. Clocks and mechanical devices historically used gravity-driven weights or pendulums to regulate motion.

Gravitationsdrevne systems are valued for their simplicity, low energy consumption, and high reliability in appropriate contexts. They require sufficient vertical head or mass and careful design to control speed, flow, and safety. Limitations include dependence on a height difference or mass, potential slowness or uncontrolled acceleration, susceptibility to environmental factors, and reduced flexibility compared with powered systems.
