KBA Cable Pneumatic/ Air Balancer Series
Knight Global's KBA Series Cable Air Balancers are used in applications where a "float" condition is beneficial. Float allows for the hands-free final positioning of an object. The up/ down speed of an air balancer is quicker when compared to a hoist and allows for a "feathering" operation when locating the load. The pendant controls are ergonomically designed incorporating color coded thumb levers.

Model Information
When specifying an Air Balancer, it is recommended to use 80% of the rated load to determine your load capacity. This approach compensates for the normal fluctuations within the plant compressed air supply. Balancers are rated at 100 psi [6.8bar] therefore use the following example to calculate exact load capability.

Formula for Air Balancer sizing:
Example: plant air 80 psi, 350 air balancer, 80% load capability (0.80 air supply x 350 lbs. = 280 x .80 = 224 lbs. load capability).

Knight KBA Series Cable Pneumatic Air Balancer

Knight Global Pneumatic Air Balancer Control Options
Control Options
Diverse Control Options
Knight Global Balancer Controls are designed for precision handling of variable loads through a variety of possibilities. UP/DOWN movements can be achieved by utilizing either a Knight Global standard pendant assembly with color coded thumb levers, or through the natural intuitive motion of a person with the In-Line Feather Touch assembly.

"Zero-Gravity" or "Floating" capabilities are achieved through precision High Relieving regulators, for a smooth and natural feel. These options help when it is difficult locating an object. Knight Global controls are designed with ergonomics and comfort in mind. Handle assemblies have a series of mounting options to help with designing the perfect system.
Internal and External Retract Controls
Knight incorporates a standard internal centrifugal retract control to insure that in the event of a sudden loss of load the cable/chain comes to an immediate and complete halt. Optional external retract control imparts a controlled condition to the spooling of the cable. By adjusting the pressure of the shock, the spool will only be allowed to move in a chosen maximum speed.

UP/DOWN Position Limit Switch
Knight balancers can incorporate up to (2) two spring loaded rod assemblies and limit switches to allow the customer the ability to relay an air pilot signal when predetermined heights have been achieved. Mounted to the bracket is a 5-way pneumatics valve that is de-actuated by the position flag as the balancer travels upward.
Note: Using an Air Balancer with a Position Limit Switch will eliminate the internal safety retract control. Check with your local safety regulations before use and/ or contact a Knight Representative.
