DEVICE AND METHOD FOR COMPENSATION OF HYDRAULIC SYSTEM WORKING FLUID THERMAL COMPRESSION Russian patent published in 2011 - IPC B66C13/20

Abstract RU 2423313 C1

FIELD: transport.

SUBSTANCE: proposed device for compensation fluid compression in hydraulic telescopic boom comprises telescopic boom inclination monitor, hydraulic fluid feeder and fluid feed controller to respond to monitor signals. Fluid feed controller ensured fluid feed from feed unit into hydraulic cylinder that controls telescopic boom extension in case preset inclination angle is exceeded to control thermal compression of hydraulic fluid, hence, to prevent spontaneous retraction of said boom.

EFFECT: boom inclination and fluid feed monitoring.
