The YBF Spring Balancers allow the worker to move the suspended tool or object up or down with very little effort. Depending on the spring adjustments, the object will remain in position or retract when no force is applied. The YBF Series has an enclosed body design to ensures operator safety so no trapped fingers or hands. The YBF has an anti-wear feature that prevents damage to the aluminium housing and can be replaced without dismantling the housing. Wire replacement can be done without dismantling the body. The containerized spring cartridge enables safe and simple servicing.
With a spiral groove on a tapered drum, the winding radius is increased to match the torque build-up of the spring., thus neutralising it and achieving a balanced condition. This is the main difference between spring balancers and retractors.
Retractors are designed to retract the cable when no force is applied. An amount of downward force must be continually applied to keep the suspended object at its extended position. The Torque output of the rewind spring increases as the cable is extended and retracting the suspended object to the uppermost adjusted position when released.
