METHOD OF SAFE CONTROL OVER HOISTING CRANE

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to method of safe control over hoisting crane. Proposed method consists in presetting tolerable parametres describing load and/or spatial position of crane jib and/or load handling fixture. It comprises measuring directly or indirectly of said parametres in operation. It includes also stoppage of implementing crane operator instruction about varying crane jib and/or load handling fixture spatial position, or limiting drive operation proceeding from the condition of drive outage in case measured parametres exceeds its preset tolerance. In compliance with this method, one tolerance is additionally varied if the other parametre falls beyond its preset tolerance. ^ EFFECT: higher safety in operation. ^ 13 cl, 1 dwg
