Firestone Airstroke Air Springs

Firestone Airstroke Air Springs are air-actuated scissor lifts that provide durable, hygienic and safe lifting solutions for applications which require pneumatic operation rather than hydraulic.

Scissor lift and tilt tables can be actuated by compact heavy-duty air bag actuators which are connected to a plant’s standard 7 bar shop air system. Such air bag (or air springs) scissor tables are used in a wide variety of applications to improve worker ergonomics and enhance plant efficiencies.

Air-actuated scissor lifts can be customised to fit specific material handling application requirements, including conveyors and lift tables in production and packaging applications.

They are easy to wash down and have no oily surfaces to attract dirt.

The scissor lifts are available in capacities from a few dozen kilograms to more than 40 tons/unit. The largest triple convoluted actuator is 940 mm in diameter and will collapse to 140 mm. The smallest is 58 mm in diameter, collapsing to 31 mm in height.

The company’s even smaller Airomatic pneumatic actuators stand 11 mm high deflated for ultracompact installation in light load applications, such as delicate conveying and food and beverage processing.

Both convoluted and rolling sleeve types of air spring operate in the same simple way: compressed air (and sometimes liquids) is directed into the air springs, expanding their fabric-reinforced rubber bladders to expand in a linear fashion from their compact collapsed state to become force-developing actuators.

The available stroke of an air spring is limited by the length of the side wall. This length is determined by stability factors (length-to-diameter considerations). These design needs can frequently be met by specifying either single, double or triple-convoluted air springs.
