The YBA Spring Balancers allow the worker to move the suspended tool or object up or down with every little effort. Depending on the spring adjustments, the object will remain in p osition or retract when no force is applied. The YBA Series has all the same features as the YBF series but also has a wire arrest system. This is ideal for applications where there is the possibility of damage to the wire stands e.g. fabrication and welding production lines.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. Please note that these Spring Balancers are NOT lifting devices and should NOT be used as a load arrester. Show more
