摘要： A quick-coupler for coupling a tool, including a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a securing element, which can be actuated by a pressure medium, is associated with the coupling mount for capturing and/or securing the first locking part in the coupling mount and a locking element, which can be actuated by a pressure medium, is associated with the locking mount for locking the second locking part in the locking mount. The securing element of the coupling mount can likewise be actuated by the pressure circuit for actuating the locking element of the locking mount, with the securing element being connected to the pressure circuit via a switching valve which is controllable by a sensor arranged at the coupling mount for detecting the locking part.

摘要： A hydraulic swivel drive for a grab that has two gripping arms or shells movable like tongs, including two swivel shafts parallel to each other and rotatably mounted in a drive housing, whose shaft ends are connectable with the gripper arms or shells, wherein the swivel shafts each have two oppositely threaded screw engagement portions, with which two pistons movable in opposite directions by means of hydraulic pressure for driving the swivel shafts are in screw engagement. Two differently large and differently contoured cylinder pressure chambers can be assigned to each piston in order to optimally adapt the cross-sectional area of the pistons for each of the reciprocating positioning movements and to appropriately select the pressure conditions. To be able to run in the differently contoured and dimensioned cylinder pressure chambers, each of the pistons is provided with different piston portions which are adapted to the respective cylinder pressure chamber.

摘要： A quick coupler for coupling a tool such as an excavator bucket, a clamshell grapple or demolition shears to a tool operator such as an excavator arm or the like. The quick coupler including a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a locking element for locking the second locking part in the locking mount is at least associated with the locking mount, with the locking element being actuable by an adjustment actuator. The quick coupler can be electrically controllable, with the quick coupler having an electric drive for actuating the adjustment actuator for the locking element.

摘要： A quick coupler for coupling a tool like for example a scoop, shell grab or demolition tongs to a tool guide such as an excavator arm or the like, including a coupling receptacle for receiving a first locking part and a locking receptacle for receiving a second locking part, wherein to the coupling receptacle a securing element is associated for catching and/or securing the first locking part in the coupling receptacle, and to the locking receptacle a locking element is associated for locking the second locking part in the locking receptacle, wherein the locking element and the securing element are actuable via a common pressure circuit having an unlocking pressure port and a locking pressure port selectively connectable with a pressure source or a return line via a valve. The securing element is actuable by a double-acting, reversible actuator and is movable both into an opening and a closing position.
