The air spring actuated lift tables offer several advantages and disadvantages when compared to hydraulic cylinder actuated lifts. The chief advantage of air spring tables is low cost. Other advantages include the fact that there are no hydraulic systems that can leak and no electrical requirements for operation. They are simply hooked up to the shop air system. The chief disadvantage to these units is the springiness of the units at any intermediate position between full up and full down. If the intermediate position springiness is a problem for an application, there are two ways to solve this problem. First the water glycol option can be chosen so that the air spring is filled with a column of water glycol. This eliminates more than 90% of the springiness. The other option is to select an electric hydraulic lift and apply the air motor option. This allows the lift to be operated on an air supply, but the lift is actuated by hydraulic cylinders that eliminate springiness.
