摘要： A connector for connecting implements on tools such as digging devices to a boom or the like comprises a body (1, 3) having first connection elements (8, 9) enabling the body to be mounted on a carrying device, second connection elements for engaging an implement with the (1,3) in the form of spaced apart first and second recesses (12, 11) on the body. The respective connection elements are mutually oriented for mounting the connector on the carrying device with the first recess (12) opening substantially downwardly and the second recess (11) opening in a direction substantially at right angles to the direction of opening of the first recess (12). At least the first recess (12) having an entrance and being substantially closeable by a closure member (13). A fluid pressure operated piston (34, 21) and cylinder (30, 22) assembly moves the closure member (13) toward or away from a position wherein the closure member substantially covers the entrance to the first recess. A spring device (31, 16) moves the closure member (13 ) toward or away from a position wherein the first recess (12) is substantially open.

摘要： A quick attachment holder for connecting an attachment to the boom arms of a loader includes right-hand and left-hand end portions connected by a semi-rigid cross tube, without additional structural cross members. A pin connection of the holder end portions to the tube causes the left- and right-hand end portions to generally move together while permitting several degrees of relative rotational movement between end portions to aid in the reconnection of the attachment even when there is slight misalignment between the holder and the attachment. The cross tube is located on the pivot center of the holder so that only torque loads are applied to the tube. The pin connection will shear if the tube is accidentally over-torqued, and individual components of the holder are replaceable.

摘要： A quick-change coupler for the work implements of an excavator beam with an adjustable support frame (4) at the beam, said support frame receiving by means of a hook jaw a cross-pipe fixed to the tool. The hook (6) widens starting at its tip and is provided on its backside with a slanted surface (7) cooperating with a corresponding bevel (23) at the tool in order that, after the engagement between hook and cross-pipe (21) and further pivoting of the support frame (4), this support frame be automatically centered until it is locked with respect to the tool.

摘要： A wedge locking element (10) for a locking device of a quick coupler A for coupling the pin P2 of an attachment to earth working machinery. The wedge locking element (10) has a sloping wedge surface (13). Projecting from the wedge surface (13) is an engagement surface (12) with which the attachment pin P2 can engage but not apply any substantial driving force to the wedge locking element (10) in the event of failure of a force maintaining the wedge locking element (10) in a position where the pin P2 is retained with the coupler A. The pin engagement surface (12) lies in a plane that is substantially in line with the direction in which the locking element (10) is, in use, moved by the driving force.

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 self-locking securing element is associated for catching and/or securing the first locking part in the coupling receptacle, and to the locking receptacle a pressure-medium-actuatable locking element is associated for locking the second locking part in the locking receptacle. The self-locking securing element of the coupling receptacle likewise is actuatable by the pressure circuit.
