Chain air / pneumatic balancers are ideal for high cycle, heavy weight applications. Many customers prefer chain overall cable in such application due to product longevity and maintenance. One important note about air balancers is the rated capacity is the balancing capacity not the lifting. In order to calculate lift capacity you can use the following formula: rated capacity x .80 x PSI. Example: 150 balancer x .80 x .80 (80 PSI) = 96 lbs lifting capacity.
