Spring Balancer are a valuable addition to your assembly line. spring balancer support heavy tools with cable tensionequal to the weight of the suspended tools, which makes them seem virtually "weightless". As the tool is repositioned the balancer extends or retracts the support cable to follow the tool's movements. Constant tension on the cable is accomplished with a spring motor and a tapered drum.The assembler has the flexibility to reposition the tool, while experiencing comfortable operation and less fatigue. Similar to a spring Balancer is the Retractor, which does not have a tapered drum. The tension on the cable increases as the cable is extend

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 oft the tools.Workers can enjoy comfortable operation with less fatigue.

  Advantages of HW series spring balancer  
1.Suspending a tool for product assembly line.
2.Frenquent fastening screws,bolts and nuts.
3.Suspending a jig,tool, welding gun etc.
4.Spring balamcer improve working efficiency and diminish worker fatigue.
5.Spring balancer make the position of a tool stable and contribute to accurate work.
7.Any electric or pneumatic power is not required and safe working is achieve
