When choosing a pneumatic or hydraulic actuator, it may not always be obvious at first whether to utilize a Rod Cylinder or a rodless Cable Cylinder. We were recently made aware of a manufacturer of an articulated lift which was at first designed around one type of cylinder, and then subsequently improved upon by changing it over to a different type of cylinder.
A pneumatic system operates under the same principles as a hydraulic system, however a pneumatic system utilizes a gas rather than a liquid. Compressed air is generally used, although nitrogen or other inert gasses can also be utilized for certain applications. With pneumatics, free air is typically drawn into a compressor where it is compressed and then stored in a receiving tank. The receiver holds a vast volume of compressed air to be consumed by the pneumatics framework as required.
