pneumatic tool balancer

Ingersoll Rand "BA" series 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 “BA” controller 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 operators way.

The primary application for the "BA" series balancer is for suspending and/or positioning constant weight items.
Servo Assist

Standard Z-Servo control (BA balancers over 200 lb (90.7 kg)) amplifies the inputs and reduces the effort required to lift the load
Safety

If the air supply is ever interrupted, the unit will maintain the load in the suspended position
Standard emergency cable retract brake

If the load is accidentally lost, a spring loaded centrifugal brake automatically stops the rapid upward cable travel
Standard overload protection

The load being lifted can never exceed the unit’s maximum rated capacity at a given air pressure
