A coupler ( ) for connecting a dipper arm ( ) of an excavator to a bucket ( ) without need for the operator of the excavator to leave the cab of the excavator, the coupler ( ) having a device for connecting it to the end of the dipper arm ( ), and a latching hook ( ) for connecting it to a bucket ( ), wherein the latching hook ( ) has a special internal profile ( ) so that when it is supporting the weight of a bucket ( ), it will tend to move to a latching position, not to an unlatching position.

Coupler for bucket excavators

A coupler ( ) for connecting a dipper arm ( ) of an excavator to a bucket ( ) without the need for the operator of the excavator to leave the cab of the excavator, the coupler ( ) having means for connecting it to the end of the dipper arm, and means, including a latching hook ( ) for connecting it to one of a plurality of different buckets ( ) and wherein locking means ( ) is provided to prevent inadvertent unlatching of the latching hook ( ), said locking means ( ) being operable from the cab. The locking means may be gravity operated and include resiliently deformable means ( ), thereon to prevent unlatching when the coupler ( ) is inverted. Alternatively, it may be spring ( ) operated in which case, further means ( ) is provided to move the locking means against the bias of the spring. Preferably, the hook ( ) has a special internal profile ( ) so that when it is supporting the weight of a bucket, it will tend to move to a latching position, not to an unlatching position.
