The
EWF Series features fully enclosed housing, fall-arrest device
(auto-brake), and manual drum locks. If a spring
breaks, the brake automatically locks to prevent tool damage.
The manual drum lock keeps the drum from rotating
to allow easy change out and maintenance of tools. Springs are
enclosed in a replaceable cartridge for safe and easy
repair. |

EWF
Series Balancers are also available in an unpainted version.
To order, add "NP" at the end of the standard "EWF"
part number. |

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 move-
ments. 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 experien-
cing 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. |
