ENDO Spring Balancers

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

Additional information

 

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.

Advantages of Using an ENDO Spring Balancers:
  • Suspends tools in assembly lines or other work areas
  • Helps the assembler with repetitive tasks such as installing fasteners: screws, nuts, bolts, etc.
  • Holds fixtures, tools, welding guns, and similar equipment
  • Improves efficiency and diminishes worker fatigue
  • Stabilizes tool positioning and contributes to work accuracy
  • Contributes to a safer working environment
  • Keeps fixtures, tools, and welding guns off of the floor and clean.
  • Eliminates the need to separately power the balancer
We offer many specialty spring balancers with safety features, and tool balancers for clean-room applications, food preparation, static discharge, and air tools. The ENDO spring balancer and tool balancer line includes many useful accessories as well.
