Tandem Cable/Chain Pneumatic Balancer Series

Knight’s Tandem Pneumatic Balancer Series is primarily designed for weights exceeding 700 lbs. [318kg]. Tandem pneumatic balancers are designed to provide the weight capacities of a reeved air balancer application, while simultaneously incorporating the extended travel benefits of a single pneumatic balancer.

Our tandem chain balancers use a custom grade 80 lifting chain specially treated to increase the life of the chain by up to 300% over standard grade 80 lifting chain.

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).

Tandem Cable Series Model Numbers:
TKBA700-073, TKBA1000-080 & TKBA1400-054

Tandem Chain Series Model Numbers:
TKBC700-067, TKBC1000-080 & TKBC1400-052
