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.
1.Suspending a tool for product assembly line. 2.Frenquent fastening screws,bolts and nuts. 3.Suspending a jig,tool, welding gun etc. 4.The balamcers improve working efficiency and diminish worker fatigue. 5.The balancers 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 achieved.
Features and Benefits
Spring Balancers are a valuable addition to your assembly line. They 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 Balancer is the Retractor, which does not have a tapered drum. The tension on the cable increases as the cable is extended.
1.Size the balancer to carry the total weight to be balanced - tool plus all accessories - and stroke (maximum to minimum height) required.
2.Size to the upper end of the capacity range of the balancer when possible.
3.Always attach secondary support cable(s) to the eyelet provided for additional safety.
4.Balancers are normally hung vertically and the rope is pulled out vertically. To prevent the rope from wearing on the guide, the rope should not be pulled out at an angle to the balancer body. The balancer can also be mounted horizontally, however a pulley system must be employed to guide the rope straight out of the balancer then down to the tool. Again, care must be taken to prevent the rope from wearing on the guide. A trolley and rail system can be used to help the balancer adjust to changing angles.
5.If multiple balancers are used in close together, install them at staggered heights to keep them from hitting each other.
6.The spring tension is factory preset to the mid-range of the rated capacity. To adjust the tension turn the worm gear or spindle clockwise to increase the tension and counterclockwise to decrease the tension.
