СПОСОБ НАСТРОЙКИ ПРИБОРА БЕЗОПАСНОСТИ ГРУЗОПОДЪЕМНОГО КРАНА

摘要

FIELD: mechanical engineering; load-lifting equipment. ^ SUBSTANCE: invention relates to overload and damage protection device of load-lifting cranes and pipelayer cranes. Proposed method comes to adjusting at least one signal in load measuring channels and/or reach, and /or angle of boom tilting by adding and/or multiplying said signal with at least one signal corresponding to at least one adjusting parameter whose value is preliminarily determined and kept in nonvolatile memory of safeguard. Signal is adjusted at no load-gripping member of load-lifting crane at zero value of mass of lifted load or load moment in lifting crane load limiting channel. For this purpose value of at least one of said adjusting parameters is determined at no load on load-gripping member of load-lifting crane. ^ EFFECT: improved accuracy of safeguard and efficiency of protection of load-lifting crane. ^ 10 cl, 1 dwg
