Tensioning systems are mechanical devices used to maintain the proper tension in cables, belts, or other components in various machines and structures. They ensure that these components operate efficiently and safely by preventing slack or excessive tightness, which can lead to wear or failure. Common applications include automotive engines, conveyor systems, and industrial machinery. These systems can be manual or automatic, with automatic systems often using sensors to adjust tension in real-time. Proper tensioning is crucial for the longevity and performance of equipment, making these systems essential in many industries, including manufacturing and construction.
