ENDO Spring Balancers

The lightweight and compact ERP and ER Series Spring Retractors are an economical choice when zero gravity is not required. ERP tension adjustment is accomplished with the integrated handle system. The unit includes an adjustable stopper that can be positioned to limit the stroke. Nylon-coated cable means clean operation - no greasy mess. The long cable travel of the ER model workies well for hanging push button pendant stations and similar devices.

EK Series Tool Balancers provide true "zero gravity" tool holding with no drifting or strain. The units have high impact cast ABS housings and the handle system for spring adjustment - See Pg. 7 for details. The tapered drums, quality springs, and ball bearings provide smooth cable travel throughout the stroke.Tension adjustment is easy and precise. CE Mark available.

EW Series Spring Balancers for tool balancing have cast aluminum case and the ratchet system spring adjustment. The cable is affixed with the "Plug-Type" cable set. EW Series Balancers are available in an unpainted version. EWF-C has several safety features.

These are are light capacity, but full of features such as:

• Plastic drum, which reduced the powder from rope abrasion
• Replaceable wire rope
• Fall arrest device to keep tools from falling if the spring breaks
• Riveted spring to enhance the safety of spring replacement
• Fully enclosed housing

The EWF Series is the "workhorse" of the ENDO line. They feature 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 Long Stroke Spring Balancers are designed for high ceiling applications. They provide true "zero gravity" tool holding with no drifting or strain. The tapered drums and quality springs and bearings provides smooth cable travel throughout the stroke. Tension adjustment is easy and precise. The ELF models offer both the automatic brake and the manual drum safety lock. In the event that a spring breaks, an automatic centrifugal brake engages and locks, preventing damage to the tool. With the manual lock engaged, the drum will not rotate. This allows for easy change out or maintenance of tools.

The Series EW-X, EWS-X, and EWF-X tool balancers are the "eco-friendly" balancers. They are the ultimate solution when particulates from the standard exterior balancer finish might contaminate food or sensitive assemblies. The basic features of the EW, EWS, and EWF tool balancers are noted on the information pages for those styles.

The EWS Series Balancers offer true zero gravity, with no drifting or strain. Tapered drum, quality springs and bearings provides smooth cable travel throughout the stroke. This model combines the smaller capacity EW series balancers with the safety features of the larger EWF series balancers. The EWS series has a manual drum lock which allows for easy change out of tools and fall arrest device. Tension adjustment is performed easily with a wrench. Additionally, the casing is fully enclosed, eliminating any potential pinch points around the drum.

The ETP High Capacity Tool Balancer offer true zero gravity, with no drifting or strain. Tapered drum, quality springs and bearings provides smooth cable travel throughout the stroke. The ETP High Capacity Tool Balancer is used for welding guns, large impact wrenches, and other heavy tools. All high capacity ETP tool balancers include the fall arrest device (auto-brake). Tapered drum, quality springs and bearings provides smooth cable travel throughout the stroke.

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 ergonomic.

The EK-N Series Balancers offer true zero gravity, with no drifting or strain. Tapered drum and quality springs and bearings provides smooth cable travel throughout the stroke. 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 EK-N 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.

The SBC-15 Series Spring Balancer is a "clean room" tool balancer used in production of electronics, pharmaceuticals, and other environmentally sensitive components. Its specially sealed aluminum case provides a Class 10 protection rating which meets most clean room requirements. The cable is sheathed in nylon to prevent metal flaking and contamination of the clean environment. It can be used with a multitude of tools including torque drivers and vacuum pin setters. Like the EK-N series, these balancers can be fitted with a grounding wire to dissipate static electricity.

Air Tool Spring Balancers (provide a safer and more organized workplace by eliminating the need for an air supply hose and a separate cable balancer. Air Tool Balancers are available with either 1/4” ID (Model ATB) or 3/8” ID (Model THB) both with braided urethane hose. The ST-30 Air Tool Balancer is to be used with feed-back air tools. The ATR Reel provides an air hose and ratchet mechanism that allows a tool to stay suspended.

ENDO Balancers have several useful accessories. The Series PTF manual trolleys are used for suspending all types of ENDO tool balancers from I-beams, railways, or jib booms. Model PTF-125 and PTF-250 are easily adjustable for different size beams. In addition, the frame is manufactured to protect the wheels from collisions with other trolleys. These trolleys can also be fitted with rubber bumpers for further protection.

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

ENDO also offers spare springs, replacement cables and hoses, extended cables, hooks, and spiral hoses
