The EWA Series Safety Balancers offer true zero gravity, with no drifting or strain. Tapered drum, quality springs and bearings provides smooth cable travel throughout the stroke. The EWA Series is used in conjunction with heaviest tools and welding machines. They are very similar to the standard ENDO balancers, but incorporate an additional safety mechanisms to prevent injury to the user. If the suspension cable is cut, a centrifugal brake engages and the drum locks. This prevents the cable from snapping back and injuring operators or damaging equipment. The distance the severed cable will travel before the centrifugal brake engages is 3.9 inches (100 mm) or less. Used by several automotive manufacturers, the EWA sets the new standard for employee safety and ergonomic.
