HIGH-RISE CRANE DEVICE, ITS CONTROL SYSTEM AND CONTROL METHOD Russian patent published in 2014 - IPC B66C13/18 B66C23/66 B66D1/50 

FIELD: transport.

SUBSTANCE: invention relates to control system for high-rise crane. Control system for high-rise crane device contains element (21) for determination of variable length hydraulic cylinder pressure and obtaining measured pressure value and control element (22) for comparison of measured pressure value with target pressure value. When measured pressure value is greater than or equal to target pressure value the tension hydraulic cylinder (23) is shortened. Due to this the tension pressure of tension hydraulic cylinder (23) is increased, tension of high-rise cable in high-rise devices is increased, and high-rise moment applied to main beam of high-rise device is increased. Invention also relates to method of high-rise device control and to high-rise device with above mentioned control system.

EFFECT: as a result, variable length hydraulic cylinder pressure is efficiently balanced thus improving high-rise crane performance.
