Tool Balancers, Load Balancers and Spring Balancers by Endo

Tool balancers, load balancers, spring balancers and air balancers are an ideal way to balance a constant load.

Endo load balancers can be identified by their conical cable drum, which ensures that the retraction force remains virtually 'constant', throughout the full cable travel. As a result, the position is retained after the attached tool has been used. In addition, no noteworthy increase in retraction force occurs when delicate operations are being performed. As a result, Endo tool balancers permit fatigue-free working, even over prolonged periods of time.

Endo provides the necessary products for the optimization of work stations. As an addition to the task saver systems we offer hose reels as well as tool retractors, tool balancers, spring balancers and load balancers. You can choose from a wide range of equipment to suit your special requirements. You can select between several options for your required specification. Test our performance. Most items are in stock and can be shipped immediately.

Endo is known for excellent service for all our products. The current range of our tool counterbalancers is constantly being extended according to our customers' requests. So please call us if you cannot find a solution for your application.

Why Choose an Endo Spring and Load Balancer
  • Endo spring tool balancers offer true zero gravity, with no drifting or strain
  • Tapered drum, quality springs and bearings provide smooth cable travel througout the stroke
  • Tension adjustment is easy and precise
  • Cast aluminum case and forged swivel hook
Required for the selection of a balancer:
  • Choose the size of the balancer with regard to the total weight to be suspended (tool plus accessories) and to the requested hoist.
  • Try to use the upper zone of the balancer's load capacity data if possible.
Installation of the balancer:
  • For safety reasons always use a 2nd load stop device, to prevent the load from falling down.
  • The tool balancer has been arranged for vertical operation. A non-vertical hoist will produce permanent abrasion. We therefore recommend using cable trolleys running within a track system, to guarantee a vertical pull.
  • If several load balances are operated very close to each other, suspend them at different heights to prevent collisions.
  • The spring tension is adjusted to the max load area. To release the initial tension turn the screw counterclockwise.
EK, EW and EWF Series Standard Spring Tool Balancers

Once you reach the 9 lb. minimum range, the EWF series tool balancers include an automatic brake and manual drum lock. In the event that the spring breaks, an automatic centrifugal brake enganges and locks preventing damage to the tool. With the manual lock engaged, the drum will not rotate, the drum will not rotate. This allows for easy change out or tooling.

Snap Back Safety Balancers (EWA)

The EWA series safety balancers are used in conjuntion with heavier tools and welding machines. This series has all of the standard features, but has an additional safety feature in case the suspension cable is cut. If the cable is cut, the centrifugal brake engages and locks the drum within 3.9 inches or less. This prevents the cable from snapping back and injuring operators.

EKN Electrostatic Discharge Tool Balancers

The EKN Series is used where electrostatic discharge can damage electronics or other sensitive assemblies, but where a "clean room" balancer is not needed. The EKN is fitted with a grounding wire, which attaches from the balancer to the secondary support hook. The grounding wire safely dissipates any static electricity charge generated by the friction of the cable while the balancer is in use.
