  • Patent number: 4565485
    Abstract: The grab (3) for handling material has two grab members (4, 5) one or both or which have tines (6, 7), the grab members being relatively movable to open or close the grab so that cohesive or rigid material can be grasped between the tines (6, 7). Additionally, one grab member (4) has side and bottom panels (21, 22) forming a scoop or bucket component and the other grab member (5) has a back panel (10) so that in one condition of the grab, e.g. when the grab members (4, 5) are closed, there is formed a complete scoop or bucket for scooping up granular or liquid material to be handled.In another embodiment, the grab member (5) may also have small side and bottom panels; in other examples the scoop may be provided wholly on one of the grab members.The grab avoids having to use separate devices respectively for grasping and for scooping operations.
