Extension Arm Pneumatic Balancer Arm Series
Knight’s Extension Arm Pneumatic Balancer Arm Series enables the operator to extend beyond the working limits of an overhead rail system within a workstation. Knight’s Pneumatic Balancer mounts to the extension arm allowing for a controlled lifting and lowering of loads. The KEAA2000 and KEAA2500 arms travel inside Knight’s RAD4110, RAD6110, or RAD7510 Aluminum Series Rail Systems.
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).
