Reeved Cable/Chain Pneumatic Balancer Series

Knight’s Reeved Pneumatic Balancer Series is primarily designed for weights exceeding 450 lbs. [204 kg]. Reeving a pneumatic balancer increases the mechanical advantage of the product, and the stroke length is half the length of a standard balancer.

Our reeved pneumatic balancers come standard with a Knight swiveling shackle on a pulley.

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).
