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.

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
• Ergonomic Up/Down pendant control for variable speed and feathering of load position
