METHOD OF OPTIMISED CONTROL OVER TELESCOPING OF SINGLE-CYLINDER TELESCOPE BOOM AND CONTROL SYSTEM TO THIS END

摘要

FIELD: transport.;SUBSTANCE: proposed control method and system are used for selection of whatever two working states of whatever telescope boom section. Said method and system set restricting condition in compliance with hydraulic cylinder stroke. When telescope boom changes from current position A to preset position B, it is possible to produce fast and easy telescoping proceeding from current position of pin mechanism and other conditions.;EFFECT: higher reliability and efficiency of high-lifting capacity cranes.;9 cl, 3 dwg
