EWA
SERIES "SNAP-BACK PREVENTION"
BALANCERS
|
|
 |
|
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. |

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. |
