Zusammenfassung:PROBLEM TO BE SOLVED: To provide a boom motion restricting device for an altitude working vehicle as improvement of a conventional arrangement involving such a risk that a boom motion after a load exceeding the load according to the setting of a load setting means 24 is applied by mistake to a load supporting means 18 when the supported load increasing operation is carried out by selecting the second restriction mode may tumble the vehicle body. SOLUTION: The boom motion restriction in the supported load increasing operation is restricted also in case the vehicle tumbling direction moment acting on the boom 14 is going to exceed the allowable tumbling moment, in addition to the conventional motion restriction.
