Spring Balancers
These new generation balancers have several new features such as, fully enclosure housing, eliminating any potential pinch points around drum, and a patented plastic wire guide at the entrance port of cable to protect casing wear.

The EWF series balancers are available from 9 kg to 120 kg capacity range and include manual drum lock. With the manual lock engaged, the drum will not rotate. This allows for easy change out or maintenance of tools. In addition, the springs are enclosed in a cassette for safe and easy repair. They also employ a taper drum to make the changeable torque constant and contribute to fatigue reduction for operator on the production.
