Features and Benefits
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
air retractors
Advantages of Using an ENDO Spring Balancer:
• 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
See chart above for measurements
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.

Balancer Cushions
Balancer Cushions protect the body of the balancer if they are placed so close together
that they might collide into one another.
