FIELD: equipment for controlling and protection of load-lifting mechanisms from overloads and damage.
SUBSTANCE: method involves controlling load-lifting mechanism by measuring signals proportional to loading and/or geometry thereof; processing signals converted to digital form in accordance with preliminarily stored signals determining order of processing in real time and indicating resulting processing data; in case allowable values of signals are surpassed, generating control signals and delivering the latter to actuating device; providing additional processing of signals characterizing results of measurement of loading and/or geometry of load-lifting mechanism by filtering thereof, including leveling down of vibrations in dynamic modes of operation of load-lifting mechanism, or changing coefficients of amplification of these signals depending on preliminarily stored characteristics of measuring devices or values of said signals; processing resultant signals in digital form.
EFFECT: increased efficiency and enhanced reliability in operation of load-lifting mechanism and interchangeability of loading sensor and crane geometry.
