Claim 14:
15. The control method according to claim 14, wherein a folding/unfolding non-compliance is detected if an actual inclination of the jib element or of one of the several jib elements, called non-compliant jib element, does not correspond to the theoretical inclination of the non-compliant jib element during the kinematics of folding and unfolding the jib,
wherein the jib occupies successive intermediate configurations between the transport configuration and the work configuration, and vice versa, during the kinematics of folding and unfolding the jib, and
wherein the folding/unfolding non-compliance is detected if the actual inclination of the non-compliant jib element does not correspond to the theoretical inclination of the non-compliant jib element in at least one of the intermediate configurations.
