Abstract

Раскрыта подвеска для соединения кранового механизма с грейфером, содержащим две или более челюсти, переводимых из разомкнутого состояния в сомкнутое состояние для захвата помещенного на жесткую поверхность сыпучего материала, содержащая по меньшей мере одну направляющую, соединенную с крепежным элементом кранового механизма, и по меньшей мере одну тягу, соединенную с крепежным элементом грейфера и установленную в направляющей с возможностью возвратно-поступательного движения относительно направляющей. В соответствии с изобретением в разомкнутом состоянии челюстей грейфера крепежный элемент грейфера расположен на расстоянии от крепежного элемента кранового механизма, определяемом тягой, а тяга установлена с возможностью свободного хода при переводе челюстей грейфера, находящихся в контакте с жесткой поверхностью, в сомкнутое состояние, для уменьшения указанного расстояния. В такой конструкции обеспечивается возможность подъема грейфера без подъема стрелы крана за счет того, что тяги свободно вдвигаются в направляющие.A suspension is disclosed for connecting the crane mechanism with a grab comprising two or more jaws being transferred from an open state to a closed state for gripping a bulk material placed on a rigid surface, comprising at least one guide connected to a fastening element of the crane mechanism, and at least one the thrust connected to the fastening element of the grapple and installed in the rail with the possibility of reciprocating motion relative to the rail. In accordance with the invention, in the open state of the grapple jaws, the grapple fastener is located at a distance from the fastener element of the crane mechanism, determined by the thrust, and the thrust is set to be free to move when the grapple jaws in contact with the hard surface are in a closed state to reduce distances. In this design it is possible to lift the grapple without lifting the boom of the crane due to the fact that the thrust is freely moved into the guides.
