摘要： A claw for grasping and recovering an object is articulated by a hydraulically responsive actuator which additionally has the capability for exerting a substantial gripping force on the object. After the object has been gripped, allowing its recovery, a pawl and ratchet carried on the claw mutually engage to lock the claw in its gripped position. The hydraulic actuator and the pawl-ratchet combination are hydraulically coupled to retain the claw in its locked gripped position in the event of hydraulic failure. With availability of hydraulic pressure, suitable hydraulic connections allow disengagement of the pawl from the ratchet when hydraulic pressure is fed to the claw actuator for causing release of the claw. In an electrohydraulic system, a solenoid actuated pawl and ratchet mechanism, with appropriate connections also provide for locking the claw in its locked position and for its subsequent release.
摘要翻译：用于抓握和恢复物体的爪由液压响应致动器铰接，该致动器另外具有在物体上施加相当的夹紧力的能力。在物体被夹紧之后，允许其恢复，承载在爪上的棘爪和棘轮相互接合以将爪锁定在其夹持位置。在液压故障的情况下，液压致动器和棘爪 - 棘轮组合被液压连接以将爪保持在其锁定的夹紧位置。随着液压的可用性，当液压被供给到爪致动器以引起爪的释放时，合适的液压连接允许棘爪与棘轮分离。在电动液压系统中，具有适当连接的螺线管致动的棘爪和棘轮机构还提供将爪锁定在其锁定位置并用于其随后的释放。

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.
