摘要： A clamshell bucket has complementary bowl sections pivotally supported from a deck, there being a generally horizontally disposed hydraulic cylinder which is trunnion mounted near its head end through linkage fixed to the top of one bowl section, and there being a piston rod for said cylinder pivotally connected at its outer end through linkage fixed to the top of the other bowl section, and there also being linkage which includes an equalizer link for insuring equal movement of the bowl sections when the hydraulic cylinder is operated. A bucket cleaner is also supported from the deck and is arranged to automatically clean the bowl sections as they are moved to open position.

摘要： A hydraulically powered material-handling device wherein rotation and/or clamping are required. Clamping force is provided down the centerline of rotation, allowing continuous rotation without the use of a swivel. This is accomplished by placing the motor or speed changer output shaft on the same centerline as the clamping cylinder. Also, all hydraulic connections are stationary, avoiding the winding of hoses around the clamping device during rotation.

摘要： A load carrier comprises two grip arms pivotally mounted at their lower ends and so foldable from and towards each other that they overlap one another, each grip arm having a link mounted thereon at a point spaced from the axis of rotation of the arm. The other ends of the links are mounted slidably along paths each extending from the vicinity of the axis of rotation of the associated arm and directed substantially to the axis of rotation of the opposite arm, the respective paths for said other ends of the two links so extending side by side that when the grip arms swing together the links intersect one another providing a fourcorner gripping space.

摘要： A grapple mechanism is suspended in a pendulous manner from the free end of a boom. To prevent free swinging, one vane member is associated with the grapple mechanism so as to move therewith. This vane, together with a stationary vane, project into a chamber or compartment containing a liquid having a desired viscosity to provide resistance to the movement of the vane associated with the grapple mechanism and thereby provide the damping action.

摘要： A device for actuating gripping or holding members is disclosed, such as the shells of a grab or the clamping jaws for the cover of a container, in which the members to which the closing or opening operation of the gripping members is entrusted to rods of a resiliently variable length which are hingedly connected, on the one hand, to the supporting member of the gripping members and, on the other hand, to a thrust ring which can be rotated about the supporting member. The thrust ring has an oscillatory movement between two angular end positions and its angular movement is controlled by a drive member.
