SWF Series spring balancers used as tool balancers

The above SWF Series shown with a shock absorbing wire stop, available on request.

Spring balancers are used in numerous applications from tool balancers to give the Gravity Free effect on its load. The SWF Series is the workhorse of the powermaster range. Tool Balancers support heavy tool loads with cable tension equal to the weight of the suspended tools, making them seem virtually weightless. Spring Balancers provide constant tension on the cable, accomplished with a spring motor and a tapered drum. The balancer extends or retracts the support cable to follow the tool's movements. The assembler can reposition the tool, while experiencing comfortable operation and less fatigue.
