The Yale YBA Spring Balancer allows the worker to mover suspended tools or objects up or down with very little effort. Depending on the spring adjustment, the object will remain in position or retract when no force is applied
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 as it's 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
The YBA series has all the features of 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 strands, e.g fabrication, welding production lines and anywhere where there is a repetitive process
