ENDO Spring Balancers and Tool Balancers by�Conductix-Wampfler�are a valuable addition to your assembly line.� 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.
