    • A coupler (10) for coupling an attachment to an excavator having a latching member (30) for retaining a rear pin (26) of the attachment and a blocking member (40) for retaining the front pin of the attachment. A hydraulic actuator (32) and spring (90) are provided for holding the latching and blocking members (30, 40) in their closed states. In the event of a failure of the actuator, the spring (90), the latching member (30) and the blocking member (40) together hold the front and rear pins (26, 26') in their respective recesses (20, 22) to allow continued operation of the coupler (10), while allowing the pins to move with respect to the coupler to create a rattling movement that can indicate to the operator that a failure has occurred.
    • 一种用于将附件耦合到具有用于保持附件的后销(26)的闩锁构件(30)的挖掘机的联接器(10)和用于保持附件的前销的阻挡构件(40)。 提供液压致动器(32)和弹簧(90),用于将闩锁和阻挡构件(30,40)保持在其闭合状态。 在致动器故障的情况下,弹簧(90),闩锁构件(30)和阻挡构件(40)一起将前销和后销(26,26')保持在它们各自的凹部(20,22)中 )以允许联接器(10)的继续操作,同时允许销相对于联接器移动以产生可以向操作者指示发生故障的嘎嘎声运动。

    • A coupler (10) for an excavator, the coupler comprising first and second recesses (20, 22) for receiving the pins (24, 26) of an attachment, a latching hook (30) movable into and out of a latching state in which it closes the second pin-receiving recess, and a blocking bar (40) movable into and out of a blocking state in which a portion of the blocking bar closes the first recess. The arrangement is such that, when the blocking bar is engaged in use by an attachment pin contained within the first recess, the action of the pin on the blocking bar urges the blocking bar into its blocking state. The blocking bar is further arranged so that, in the blocking state, it lies in the path of the latching hook and that, upon movement of the latching hook out of the latching state, the latching hook engages with the blocking bar to retain it in the blocking state.
