Scissor lifts and tilt tables make many assembly, construction, fabrication, manufacturing, materials handling and maintenance tasks easier and safer.
They are particularly useful when users need to lift and then work at different heights and angles with heavy materials involved in mechanical and building maintenance and fabrication, distribution and warehousing, industrial and construction tasks and process and materials handling applications, ranging from food and beverage to primary product and resources processing.
Pneumatically actuated scissor lifts and tilt tables 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.
Scissor lifts and tilt tables actuated by Air Springs Airstroke actuators also eliminate one of the weakest links in pneumatic actuation. The seals in traditional cylinders used to actuate the equipment involved.
This advantage 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, says pneumatic actuation and isolation specialist Simon Agar.
Mr Agar, General Manager of Air Springs Supply Pty Ltd, has more than 20 years experience with Firestone air spring actuators known as Airstrokes.
He says Airstrokes are, in essence, heavy-duty balloons. While Airstrokes are available in a variety of styles, sporting differing components that control the shape and path of axial extension (including single, double and triple convoluted, as well as rolling sleeve), their basic design is the same.
“These highly engineered rubber and fabric balloons or air bags are flexible-wall, bellows-type air cylinders which are ideally suited to engineering of assemblies for high-repetition, high reliability tasks, for which they are inflated and deflated to achieve their purpose, he says.
Traditional cylinder designs contain a piston sliding within a housing of circular cross-section connected to the work by a rod passing through one end of the device. This design necessitates several guides and seals, which align and seal the sliding surfaces. These allow a pressurised, contained column of fluid to apply force to the piston.
The advantage of an air spring is that it uses none of these components to contain and channel its column of fluid, says Mr Agar.
