We offer the Yale YBA wide range of spring balancers with capacities from 7 to 70kgs. These tool balancers are designed with safety being the primary feature, they have a built in fall arrest in the event of a failure and therefore are particually suited for use supporting equipment that is used above people while they are working because the fall will be arrested.
The YBA 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. Containerised spring cartridge feature for safe and simple servicing and replacements.
Designed for heavy industrial applications, the Yale YBA range are available with cable lengths up to 2.3 metre for capacities up to 70kgs.
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 to use, increases productivity and reduced 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.
YBA series, 9 - 70kgs with additional safety-device (wire arrest mechanism)
The YBA series has a wire arrest system. This is ideal for applications where there is the possibility of damage to the wire strands, e.g. fabrication and welding production lines as this range provide added safety., They have enclosed body design ensuring operator safety; no trapped fingers or hands.
Possible Applications include
- Resistance spot welding machines.
- Measuring machines.
- Compressed air equipment.
- X-Ray apparatus.
- Power tools (electric driven).
- Welding machines.
- Welding templates.
- Paint spraying apparatus.
- Cages.
