Claim Text:
1. An articulated operating arm on which one or more implements are or can be mounted, comprising substantially three articulations which are pivotally connected to each other, which substantially three articulations comprise a first articulation configured for attachment to a construction machine or ship, a second articulation and a third articulation which is configured for connection to the one or more implements, which second articulation is pivotally connected at a first end to the first articulation and at a second end to the third articulation, wherein the substantially three articulations are rotatable adjacently to each other in order to form a shortened arm, such that during the rotation of the articulations, a mechanical locking of the third articulation occurs between the second and the first articulations; wherein the third articulation and the second articulation each respectively comprise a third and a second coupling means and these are arranged such that when the third and the second articulation rotate adjacently to each other, a mechanical locking of the third articulation occurs relative to the second articulation by coupling between the third coupling means and the second coupling means; wherein the first articulation comprises a first coupling means which is arranged for the purpose of coupling, after further rotation of the second articulation together with the third articulation to the first articulation, to the third coupling means.
