Strand jack

A strand jack is a mechanical device used for lifting heavy loads, often in construction, engineering, and maintenance applications. It uses a series of high-strength steel cables (strands) to lift and lower objects, providing a controlled and efficient means to handle large structures such as bridges, oil rigs, and heavy machinery. The strand jack operates by employing hydraulic or mechanical tensioning systems to pull the strands through a series of jacks, allowing for precise control over the movement of the load.
