Product Description

Spring Weight Balancer

Introduction:
Spring balancer is an auxiliary tool used with operating tools.The tension is kept stable on even if the cable is pulled out or retrieved because of the tapered drum. So Spring balancers can hold the tools suspended in hollow and work for flexible positioning of the tools. Workers can enjoy comfortable operation with less fatigue.


Advantages: 
Improve working efficiency and diminish worker fatigue.
Make the position of a tools table and contribute to accurate work.
Available for keeping a tool not damaged.
Any electric or pneumatic power is not required and safe working is achieved.



How to adjust spring tension: 
Worm gear system, Ratchet system or Handle system are available and dependent on the models. Clockwise adjustment increases the spring tension and Counterclockwise adjustment decreases the spring tension. (The spring tension has been set at the middle of capacity in advance prior to shipment)
