Abstract
So as to avoid installing a heavy remote handling machine in a containment comprising a lifting unit, such as a travelling crane, the present invention proposes an autonomous remote handling machine (20) suitable for being suspended from the hook (b 16) of this crane. This machine (20) includes a support (22), a gripping arm (24) and a counterweight (26) being joined to said support around a normally horizontal axis (26). A device (44) detects any possible slanting of the support (22) with respect to vertical in order to control any modification of the orientation of the counterweight (26), independently of the orientation of the arm, so as to annul any detected slanting.
