The Yale YBF series spring balancer incorporates an enclosed body design, which ensures operator safety; 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 containerised spring cartridge enables safe and simple servicing.
The Yale YBF range is available with a choice of cable lengths ranging from 1 to 2.5m long for capacities from 1kg up to 200kg.
Tool balancers / Spring balancers allow the worker to move the suspended tool or object 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 (let go of). Set the tool balancer to the same weight as the tool, and the weight will be balanced. Add a little more tension to the spring, and the load will retract when you let go. The more tension applied, the quicker it will retract, and therefore, the more effort will be required by the user to pull down the tool when next required. Simple to set up, adjust, and use, it increases productivity and reduces fatigue and the risk/potential if injury.
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.
