Abstract
Изобретение относитс к подъемно-транспортному машиностроению и может быть использовано при обслуживании кранов мостового типа. Цель изобретени - улучшение эксплуатационных характеристик механизма путем уменьшени хода силового цилиндра. Устройство содержит платформу и два укрепленных на ней подъемных элемента, каждый из которых выполнен в виде шарнирно-рычажной системы типа нюрнбергских ножниц, представл ющей собой набор шарнирно соединенных одна с другой планок 5, в одной из чеек которой размещен дополнительный шарнирно-рычажный механизм типа нюрнбергских ножниц, состо щий из планок 16, длина которых кратна длине планок 5. Внутри чейки дополнительного механизма установлен гидроцилиндр 15. 3 ил.The invention relates to a lifting and transport machinery and can be used when servicing bridge type cranes. The purpose of the invention is to improve the operating characteristics of the mechanism by reducing the stroke of the ram. The device contains a platform and two lifting elements fixed on it, each of which is made in the form of a hinged-lever system of the Nuremberg scissors type, which is a set of levels 5 pivotally connected to one another and in one of the cells of which an additional Nuremberg-type hinged-lever mechanism is placed scissors, consisting of strips 16, the length of which is a multiple of the length of the strips 5. A hydraulic cylinder 15 is installed inside the cell of the auxiliary mechanism. 3 Il.
