Support units are built by using circular standard air pads, whose performances are described on sheet S02.|
These are completed with a steel frame and include their support at rest and a throttle valve.
Support units are for use with solid loads having flat support faces underneath. A minimum of 3 units is used per load.
Bearing surface should be at least half of support area.
· The independent supply, with flow adjustment individually for each support, allows the handling of excentric loads (with each support always within its capacity range).|
· Every support is connected to air by means of flexible pipes, with 16 or 19 mm ID.
· The manifold is connected to the air supply system with a flexible pipe, whose section is calculated as a function of the number of support elements, of the required air flow (depending on floor quality) and of tube length. A pressure regulator is not necessarily required.
Example: Tube ID = 19 mm for 4 units ě 600 on smoothed concrete without joints.
