A grapple-heel rack having a frame, a grapple, and first and second angle-enabler catches. A grapple attachment (which may be or may include a universal joint) may be used to support the grapple from a nose of the frame. A mechanical grapple return system may be used to return the grapple from anon-neutral position to a neutral position. At least one method for using the grapple-heel rack.

The invention concerns an arrangement for the guidance of flexible lines that run from a crane arm (3) through its end section (2) to a tool (4), that is suspended at the crane arm through a link arrangement (5) and a frame that is a component of a rotator (6) for rotation around a vertical first axis (A) and in a cardan manner around second (B) and third (C) horizontal axes,

For the discrete and protected passage of hoses, it comprises a first holder (35) in an opening (3A) of the end section (2), a second holder (38) in a central region of the rotator (6), a first hose package (1A-1D) that extends between the said first (35) and second holders (38), a penetration (26) in a central region of the rotator (6) and permitting hydraulic fluid to pass through the rotator (6) and onwards to a lower part (18) of the same at least one of the said second (B) and third (C) horizontal axes comprises an open joint.

A power bucket having a first and second bucket half pivotally secured together about a main axis by a pivot pin. The bucket halves are movable between an open and a closed position. A head is disposed above the bucket halves and at least one arm pivotally connects the head to one bucket half while at least one second arm is pivotally connected between the head and the other bucket half. A cylinder support is pivotally mounted to the pivot pin and one end of a hydraulic cylinder is attached to the pivot support. The other end of the cylinder is attached to the bucket. Upon actuation of the cylinders, the cylinders move the bucket halves so that a cutting edge of the bucket half moves in a substantially horizontal plane.

The invention relates to a slurry wall grab having a hybrid drive comprising at least one pulley block, at least one hydraulic actuator, and at least one energy store, wherein the hydraulic actuator and the pulley block are configured to open and/or close a grab jaw of the slurry wall grab, and wherein the energy store can be charged by actuating the pulley block.

A collection device can include an enclosure defining a top opening and a bottom opening; a latch coupled to the enclosure and configured to selectively secure a base to the enclosure proximate to the bottom opening; and an actuator coupled to the latch, the actuator controlled remotely and configured to open the latch and thereby release the base.
