Abstract
Изобретение относитс к подъемно-транспортному машиностроению, а именно к ограничител м грузоподъемности кранов-трубоукладчиков. Цель изобретени - повышение надежности. Датчик 6 усили установлен на стреле 3 и через рычаг 7 св зан с эксцентриковым пальцем 2, несущим серьгу 1 с блоком 4 грузового полиспаста 5. Датчик 9 усили св зан с гидроцилиндром 10 противовеса 11. Датчики 6, 9 через элемент 12 сравнени подключены к узлу 13 сигнализации и отключени крановых механизмов. При перегрузке крана по сигналам датчиков 6, 9 срабатывает элемент 12 и узел 13 информирует оператора о перегрузке и отключает механизмы. 2 ил.FIELD OF THE INVENTION The invention relates to a hoisting and transport machinery, namely, load limiting cranes, pipelayers. The purpose of the invention is to increase reliability. The force sensor 6 is mounted on the boom 3 and is connected through the lever 7 to the eccentric pin 2 carrying the link 1 with the block 4 of the cargo polyspast 5. The sensor 9 is connected to the hydraulic cylinder 10 of the counterweight 11. Sensors 6, 9 are connected to the node via the reference element 12 13 alarm and shutdown crane mechanisms. When the crane is overloaded, signals from sensors 6, 9 trigger element 12 and node 13 informs the operator of the overload and turns off the mechanisms. 2 Il.
