    摘要： An anti-release mechanism of a pin-grabber coupler securing a work tool connected to a work machine is disclosed. The anti-release mechanism comprises an actuator, a wedge, a latch, a guide rod connecting the wedge and the latch, and a bias member on a first guide rod end of the guide rod biasing the latch and the wedge together. The wedge and the latch lock around a pin of the work tool and maintain the wedge against the pin of the work tool during a loss of engagement force of the wedge against the pin.

    摘要： An attachment system for a work vehicle implement includes an implement attachment assembly. The implement attachment assembly includes a support structure coupled to a receiver assembly. The support structure includes a first mounting feature configured to engage a first corresponding mounting feature extending downwardly from a bottom surface of a work vehicle, and a second mounting feature configured to engage a second corresponding mounting feature extending downwardly from the bottom surface of the work vehicle. The first and second mounting features of the support structure are spaced apart from one another along a longitudinal axis relative to a direction of travel of the work vehicle, and the first and second mounting features of the support structure are configured to substantially block horizontal and vertical movement of the support structure relative to the work vehicle via engagement with the first and second corresponding mounting features of the work vehicle.

    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.

    摘要： A quick coupler includes a coupler body having a first hook, a lock member, a slidable second hook, a hydraulic cylinder, and a connecting pin connecting the cylinder and coupler body. The lock member is movable between locking and unlocking positions in which the lock member protrudes into and retracts from an opening of the first hook. The cylinder includes first and second end portions connected to the coupler body and the second hook, respectively. The cylinder extends and contracts to cause the second hook to slide away from and towards the first hook, respectively. The coupler body includes a support hole moveably supporting the connecting pin in an extension and contraction direction of the cylinder. The first end portion of the cylinder moves away from the second end portion within a movability range of the connecting pin to move the lock member from the unlocking to locking position.

    摘要： Provided is a vibration damper for a high load, including: a vibration body support portion having first shaft support portions; rotation shafts that are rotatably installed at the first shaft support portions, have eccentric portions eccentric with respect to rotation centers of the rotation shafts and are spaced a predetermined gap from each other; a support portion having second shaft support portions on which the eccentric portions are rotatably supported; an elastic member that is installed between the vibration body support portion and the support portion or between the vibration body support portion and the second shaft support portions and that elastically supports the support portion with respect to the vibration body support portion in an upward direction; and a rotation synchronization unit that is installed at the rotation shafts so as to synchronize rotation directions of the rotation shafts according to vibration. The vibration damper for a high load can be applied to various construction machines, and excavators and can prevent vibration generated from various attachments from being transferred to a boom or car body of an excavator or a construction machine.

    摘要： A quick coupler for coupling an attachment, such as a digging bucket, to an evacuator machine. The quick coupler includes a first fixed jaw for a first coupling pin of the attachment. The quick coupler includes a latch cooperating with the first fixed jaw, which is moveable to a latched position for retaining the first coupling pin. A moveable jaw is provided that is able to slide, under power of a hydraulic ram, to a closed position retaining the second coupling pin. A locking arm assumes a locked position, while the latch assumes the latched position, preventing withdrawal of the moveable jaw from the closed position. Consequently, in the event of a hydraulic failure the locking arm simultaneously locks both the first attachment coupling pin, by means of the latch, and the second attachment coupling pin by means of preventing movement of the movable jaw from the closed position.

    摘要翻译： 用于将诸如挖掘桶的附件联接到排气机的快速联接器。 快速联接器包括用于附件的第一联接销的第一固定夹爪。 快速联接器包括与第一固定夹爪配合的闩锁，其可移动到用于保持第一联接销的闩锁位置。 提供了可移动的钳口，其能够在液压压头的动力下滑动到保持第二联接销的关闭位置。 锁定臂处于锁定位置，同时闩锁呈现锁定位置，从而防止可移动钳口从关闭位置的撤回。 因此，在液压故障的情况下，借助于防止活动夹爪从关闭位置的移动，锁定臂同时通过闩锁和第二附接联接销同时锁定第一附接联接销。
