IMPLEMENT COUPLING SYSTEM FOR A POWER MACHINE

摘要

An implement locking system (200) for locking an implement (138) to an implement carrier (140) of a power machine (100) is disclosed. The implement locking system includes a locking mechanism (312; 314; 360) having a locking pin (318) with an extended position for locking the implement to the implement carrier and a retracted position for mounting or removing the implement from the implement carrier. A user input (220) provides a signal indicative of an operator intent to move the locking pin to the retracted position. A locking actuation valve (340) controls the locking mechanism to automatically and continuously extend the locking pin in the absence of the signal being indicative of the intent to move the locking pin to the retracted position. The locking actuation valve moves the locking pin to the retracted position only for the time corresponding to the signal being indicative of moving to the retracted position.
