Forces on the building
In the case of pushrod drives for discharge push floors with several
pushrods, the hydraulic cylinders have pipes laid in opposite flow
directions, i.e. the first cylinder pulls, the second cylinder pushes, the
third cylinder pulls, etc. The cylinder with the lowest pressure drops
generally moves first into the end position, then the next one.
When all cylinders are in the end position, the oil pressure increases
up to the response pressure for the pressure diverter valve (set to 190
bar at the factory) and this switches to the opposite direction.
FG1 Maximum tensile force on the weld base of the bunker upwards
per metre length
FS
Total standard forces on the front panel (slot discharge)
FR
Total standard forces on the back panel
FR1 Standard force of a pushrod on the back panel
FS1 Standard force of a pushrod on the front panel
