    摘要: A grab bucket having a grab (1) formed of shells (2) opposed to each other, a lower frame (3) for pivotably supporting the shells, an upper frame (5) placed above the lower frame and connected with the shells through the suspending arms (4), an intermediate movable frame (7) placed between the upper and lower frames and connected with the lower frame through a hydraulic cylinder (6) with a piston (6b), and a wire rope (8) for suspending and closing the grab is provided with a by-pass passage (25) for connecting the upper end portion of the hydraulic cylinder with the cylinder body of the hydraulic cylinder. Through the by-pass passage, an oil in an upper chamber defined above the piston (6b) flows into a lower chamber defined below the piston, thereby to accelerate the movement of the piston in the hydraulic cylinder. Thus, the scrap or other objective materials grabbed by the grab bucket of the invention can be efficiently thrown off by vibration and the action of inertia of the objective materials only by fully opening the grab.

    摘要: The invention provides a method and apparatus for controlling the level of clamping pressure applied by a clamp (14) to a load (16). A pump (20), whose output is controlled by a normally open valve (34), establishes an initial level of clamping pressure. Through the use of a number of controllable fluid discharge means (50, 52, 54), this pressure is automatically increased in increments depending upon the resistance of the load to the clamping pressure exerted. In a preferred embodiment, the controllable fluid discharge means include discharge cylinders (58, 70, 90) that contain predetermined volumes of fluid dischargeable by free-floating pistons (62, 82, 92) residing therein. The outputs of the discharge cylinders are controlled by pressure-responsive valves (72, 92) to produce the desired relationship between clamp pressure and load rigidity.

    摘要: The invention relates to a pincer grab (1), comprising:
    a frame (2) with attachment means (3) for coupling to a hoisting device;
    two jaws (6,7) carried by that frame (2) and pivotable around mutually parallel horizontal centre lines (4,5), which jaws have complementary edges (8,9) facing one another and which can together form a grab;
    a drive unit, for example at least one hydraulic cylinder (10), with coupling means (11) for coupling to a controllable energising unit, for example a source for a medium under pressure; and
    transmission means (14,15,16,17,18,19) which are arranged between the drive unit and the jaws;
    whereby the disposition is such that through suitab­le energising of the drive unit the jaws can be moved between a closed position, wherein they together form a grab, and an open position.
    The invention has for its object to embody a pincer grab such that no torsional forces can occur. The pincer grab according to the invention displays to this end the feature that the transmission means are arranged such that the forces produced by the drive unit in a vertical plane are transmitted in substantially that same vertical plane onto the jaws, such that no or only negligible torsion can occur in the transmission means.
