と干渉する位置に衝合部を形成したことを特徴と
する、高所作業が可能なクレーン車。 A swivel post that is rotatably mounted on the vehicle frame,
A multi-stage boom pivotally supported on the swing post so as to be able to rise and fall; a hook that is suspended from the tip of the multi-stage boom so that it can be raised and lowered via a wire that is connected at one end to a winch drum; In a crane vehicle comprising a hydraulic actuator that performs boom-related work such as extending/contracting, raising and lowering, and turning a swing post, and a hydraulic control valve that supplies pressure oil to these hydraulic actuators, a crane is provided that can be attached to and detached from the tip of the multi-stage boom. A bucket for high-place work is provided, and the wire for lifting the hook is suspended between the multi-stage booms so that the distance between the hook and the tip of the multi-stage boom is maintained constant regardless of the expansion and contraction of the multi-stage boom, and A crane vehicle capable of working at heights, characterized in that the work bucket has an abutment part formed at a position that interferes with the lowering of the hook when the bucket is attached to the tip of the multi-stage boom.
