LODGMENT SUPPORT FOR TRANSPORTATION OF LONG NON-RIGID AND NON-RESISTIVE TO VIBRATION CARGO Russian patent published in 2009 - IPC F16M11/00 B60P3/11 

FIELD: transportation.

SUBSTANCE: support is made in the form of lodgment with cushion for cargo. The lodgment is fitted on supporting base of carrier vehicle and is connected with the latter through hydropneumatic cushioning supports. Device for rigidity adjustment comprises gas pressure source, gas-distributing unit, connection lines for high-pressure and low-pressure cylinders with gas transfer compressor installed in these lines; branching line connecting pressure source with cylinder gas chambers in which line pressure sensor and normally closed electropneumatic valve is installed. Control unit is connected with pressure sensor and controls operation of gas-distributing unit, electropneumatic valve and compressor. Damping regulator includes two throttling devices with adjustable hydraulic resistance which are installed in hydraulic lines respectively, and the mentioned control unit which controls operation of throttling devices and reads their signals of hydraulic resistance current values. Adjustment of support rigidity is performed by raising or lowering pressure in gas chambers of liquid gas cylinders. Damping is performed by reducing or increasing area of throttling devices flow sections.

EFFECT: reliability enhancement.
