Ingersoll Rand (BA) Series (Zimmerman) pneumatic balancers have no pendant controls and are used for single-load suspending applications – either at a fixed height or where both hands are used to manually raise, lower, and position (or “float”) a load. The operator experiences virtually no part weight or resistance in manipulating the load. The controller on this air balancer is a self-relieving regulator that automatically adds or exhausts air to raise or lower (float) the load to the desired height where it will remain suspended. The regulator can also be adjusted to slowly raise a load up and out of an operator’s way. The primary application for the “BA” series balancer is for suspending and/or positioning constant weight items.

DURABILITY: Balancers feature all-steel housing, engineered plastic, aircraft grade wire rope and self-closing cast safety hook.

RELIABILITY: Features include precise positioning, a pre-lubricated piston chamber, intuitive speed control, and continuous duty operation.

SAFETY

• Standard emergency cable retract brakes mean that if your load is accidentally lost, a spring-loaded centrifugal brake automatically stops the rapid upward cable travel.
• If the air supply is ever interrupted, the unit will maintain the load in the suspended position.
• The load being lifted can never exceed the unit’s maximum rated capacity at a given air pressure, providing intrinsic overload protection.
• The optional Z-stop eliminates the down-drift of suspended loads within 6 inches (152 mm) if air supply is shut down.

PRODUCTIVITY: Gain flexibility, with ultra-low air consumption, clean oil free operation, and cable travels of up to 120 inches depending on model.

• Suspension kits are available for virtually all enclosed track manufacturers, as well as I-beam, Patented/Hardened track, and Hook mounted configurations.
• Standard Z-Servo control (BA balancers over 200 lb., or 90.7 kg) amplifies the inputs and reduces the effort required to lift the load.

Ingersoll Rand Equal Air (EA) Series (Zimmerman) Balancers are used for handling multiple (up to 3) loads within a 40 lb. (18.1 kg) weight range without the need to adjust the controls. When the pendant is in the LO- and UN-LOAD position, balancer air pressure is released to allow the lighter loads to be in balance. When the pendant is in the HI-LOAD position, no pressure is released, and the heaviest load can be balanced. These pneumatic balancers are ideally suited for applications where up to 3 load sizes are frequently lifted, and operator hands-on the part is required. The UN-LOAD position is also often used for handling device balancing (loaded/unloaded).

Ingersoll Rand Air (ZA) Series Balancers (Zimmerman) are the most common air balancer/control combination, designed for high-speed, precision handling of variable weight loads. Up/down movement is accomplished through the use of an ergonomically designed pendant with low-effort, color coded thumb levers. After positioning the load with the pendant control, the unit defaults into a balanced load condition that allows the operator up to 18 inches (457 mm) of travel to manually adjust the load for final positioning.
