Ingersoll Rand's Zimmerman Pneumatic Balancer

IR Air Balancer

Pneumatic Balancer with Bar Stock Gripper Tool

What are the Benefits of Tool Assembly Systems?

Air Balancers are a perfect combination of durability and usability. With the ability to float the load, precise manual movement and placement can be achieved without the need to jog the hoist. Pneumatic balancers operate within a capacity range of 150 to 500 pounds. The ZA version of the Zimmerman air balancer is the most common balancer option. Pneumatic balancers come with a simple ergonomic pendant handle with a green lever for up and a red lever for down. This pendant design allows for high speed movement of multiple weights. With this handle design, the Ingersoll Rand balancer offers a float mode with 18 inches of travel after the load has been positioned.

Features Include:

Simple air piston design is extremely durable, even in harsh applications.
Maintenance-free design is also fast, producing speeds up to 200 feet per minute.
Lube-free design is rated for continuous duty.
Standard overload protection - As air pressure is used to lift the load, it also limits the overall capacity. This prevents the unit from exceeding the maximum rated capacity.
These air balancers require only 1/8 cfm per lift. (On average, this is 50 times less than what it would take to operate a true air hoist.)
The unit will maintain the load in the suspended position if the air source is ever lost, and a spring-loaded centrifugal brake automatically stops the rapid upward cable travel if the lift cable is cut or if the load drops.
Control Options:
- ZA CONTROL: Pendant or integrated up/down control.
- B CONTROL: No control package. Used when integrated with devices that already have controls.
- BA CONTROL: For balancing a single, constant load. Perfect for tool, weld gun, or fixture suspension where the load is never removed.
- EA CONTROL: Load balancing for 3 loads - High Load, Low Load, and No Load. Used primarily with Load/no load applications.
Suspension kits are available for virtually all enclosed track manufacturers, as well as I-beam, Patented/Hardened track, and Hook mounted configurations
Available in 5 standard capacities: 150 lbs. (68 kg), 200 lbs. (90 kg), 350 lbs. (160 kg), and 500 lbs. (225 kg).

Unified Industries Pneumatic Cable Balancers

Unified Industries is a subsidiary of Columbus McKinnon that offers high-quality products with state-of-the-art motion technology for optimal performance. Their systems aim to prioritize safety and productivity and are engineered with ergonomics in mind.

The Unified pneumatic cable balancers are a perfect solution for transferring loads when you need more precision than a pneumatic hoist offers. They offer easy to adjust up and down speeds, with a “float” mode that gives you more accuracy for finishing the job.

Features and Benefits:

Load Safety - Check valve in case of loss of air supply.
Energy Efficient - Only a fraction of CFM per cycle when compared to a pneumatic hoist.
Longer Service Life - Robust precision mechanical design and powder-coated housing ensure trouble-free extended life.
Non-lubricated air assures a clean environment.
All non-reeved balancers come equipped with a 9-meter cable.
