(Also known as Tool Balancer / Retractable Tool Hanger / Zero-Gravity Balancer)
A Spring Balancer is a mechanical lifting and support device designed to suspend and counterbalance the weight of tools or equipment, allowing them to be moved freely and effortlessly in any direction during operation. It uses a coil spring mechanism enclosed in a housing to provide constant tension on a retractable cable or rope, effectively making the suspended tool “weightless” in the operator’s hand. Spring balancers are widely used in assembly lines, automotive workshops, welding stations, and manufacturing plants to improve ergonomics, safety, and productivity.
