<p>The invention relates to an arrangement for securing, in a parking position, a part (3) of an implement attachment to the free end (2f) of a crane arm (2e), wherein said implement attachment part (3) is pivotally mounted on said free end (2f) by means of at least one pivot shaft (6a, 6b), wherein said implement attachment part (3) comprises at least two parts (3a, 3b) which are rotatable relative to each other, and wherein said parts are adapted for rotation in relation to each other by means of a piston-cylinder device (7). At least one tension-force take-up device (4a, 4b) is mounted between a securing device (10) associated with the implement attachment part and a securing device (11a, 11b) associated with the crane arm. Activation of the piston cylinder device (7) can bring the implement attachment part (3) to a parking position beneath or above the crane arm (2e).</p> |
