Description

гидроцилиндра 1, размыка  гидрозамок 27, а по трубопроводу 19 поступает в полость Б дл  вдвижени  выносных опор 7.the hydraulic cylinder 1, the hydraulic lock 27 is open, and the pipeline 19 enters the cavity B to move the outrigger supports 7.

Гидроцилиндр 2 аналогично управл етс  секцией 12 гидрораспределител .The hydraulic cylinder 2 is likewise controlled by a section 12 of the hydraulic distributor.

Перемещение крана, вывешенного на выносных опорах, осуществл етс  при одновременном перемещении выносных опор вправо или влево носредством одновременной подачи рабочей жидкости через дополнительную золотниковую секцию 13 по трубопроводам 20, 17 в разноимшные полости гидроцилипдров 1, 2.Moving the crane hung on the outrigger supports is carried out with simultaneous displacement of the outrigger supports to the right or left by means of simultaneous supply of the working fluid through the additional spool section 13 through pipelines 20, 17 into the opposing cavities of the hydroclipdra 1, 2.
