Single Cable/Chain Pneumatic Balancer Series

Knight’s Single Pneumatic Balancer is 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 a pneumatic balancer is quicker when compared to a hoist and allows for a “feathering” operation when locating the load. The pendant controls are ergonomically designed and incorporate color-coded thumb levers.

When specifying a pneumatic balancer, it is recommended for working loads to use 80% of the operating capacity for lifting applications. This approach compensates for the normal fluctuations within the plant compressed air supply. Working loads include part weight and handling device weight. Balancers are rated at 100 psi [6.8bar] therefore use the following example to calculate exact operating capability.

Formula for pneumatic balancer sizing:

Example: plant air 60 psi, 350 air balancer, 80% load capability (0.60 air supply x 350 lbs. = 210 x .80 = 168 lbs. operating capability).
