EWA SERIES "SNAP-BACK PREVENTION"
BALANCERS

ewa series snap back prevention balancer

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 ergonomics.

Features and Benefits
Advantages of Using an ENDO Spring Balancer:
ENDO Spring Balancers are a valuable addition to your
assembly line. They support heavy tools with cable tension
equal to the weight of the suspended tools, which makes
them seem virtually "weightless". As the tool is repositioned
the balancer extends or retracts the support cable to follow
the tool's movements. Constant tension on the cable is
accomplished with a spring motor and a tapered drum. The
assembler has the flexibility to reposition the tool, while
experiencing comfortable operation and less fatigue. Similar
to a Balancer is the Retractor, which does not have a
tapered drum. The tension on the cable increases as the
cable is extended
• Suspend tools in assembly lines or other work areas
• Help the assembler with repetitive tasks such as
   installing fasteners: screws, nuts, bolts, etc.
• Hold 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
Application Guidelines
• Size the balancer to carry the total weight to be balanced - tool plus all accessories - and stroke (maximum to
   minimum height) required.
• Size to the upper end of the capacity range of the balancer when possible.
• Always attach secondary support cable(s) to the eyelet provided for additional safety.
• Balancers are normally hung vertically and the rope is pulled out vertically. To prevent the rope from wearing on the
   guide, the rope should not be pulled out at an angle to the balancer body. The balancer can also be mounted
   horizontally, however a pulley system must be employed to guide the rope straight out of the balancer then down to
   the tool. Again, care must be taken to prevent the rope from wearing on the guide. A trolley and rail system can be
   used to help the balancer adjust to changing angles.
• If multiple balancers are used in close together, install them at staggered heights to keep them from hitting each other
• The spring tension is factory preset to the mid-range of the rated capacity. To adjust the tension turn the worm gear
   or spindle clockwise to increase the tension and counterclockwise to decrease the tension.
