Scissor lift and tilt tables actuated by Air Springs Airstroke actuators eliminate one of the weakest links in pneumatic actuation.  

Scissor lifts and tilt tables find use in various assembly, construction, fabrication and maintenance applications.  

They are particularly useful when users need to lift heavy materials and work at different heights or angles in building maintenance and fabrication, distribution and warehousing as well as industrial and construction tasks.  

Pneumatically actuated scissor lift and tilt tables are designed to offer reliable and safe performance. If the power cuts out or the system falters, then the actuator will still compress gently with the air (or water) inside offering resistance.  

One of the weakest links in pneumatic actuation is the seal in traditional cylinders used to actuate the equipment. This is eliminated when the equipment is actuated by Air Springs actuators.  

Pneumatic actuation and isolation specialist Simon Agar says that this advantage in Air Springs Airstroke actuators is especially critical in aggressive atmospheres laden with dust and waste where such cylinders can clog up and wear prematurely over the millions of cycles for which they must operate.  

Mr Agar, General Manager of Air Springs Supply Pty Ltd has more than 20 years of experience with Firestone air spring actuators known as Airstrokes.    

Describing the advantages of Airstroke actuators, Mr Agar says that they are basically designed as heavy duty highly engineered rubber and fabric balloons or air bags with flexible wall, bellows-type air cylinders.  

The actuators are ideally suited to engineering of assemblies for high repetition, high reliability tasks for which they are inflated and deflated to achieve their purpose.  

Unlike traditional cylinder designs, an Air Spring contains its column of air in a fabric-reinforced rubber envelope or bellows. The ends are sealed by bead plates, which are crimped around the bead of the bellows. These plates contain the attachment hardware for the part, normally a blind tapped hole called a blind nut.  

An air fitting, generally in one bead plate allows fluid (air) to be introduced into the chamber. The fabric in the side wall of the bellows restricts radial expansion, so pressure is built up, causing axial extension to provide the scissor lift or tilt function required.    

Air Springs offers a broad range of air spring actuators to Australian industry.
