Summary:PROBLEM TO BE SOLVED: To place sufficiently kneaded concrete with no separation of materials when placing the concrete from a chute for a concrete placing crane device, keeping the placing concrete to be least splashed and improve workability and working environment. SOLUTION: A concrete placing crane device includes a supporting post 1 extending in the vertical direction, an arm 10 provided for the supporting post 1 so as to be turned around the axis of the supporting post 1 and a concrete placing chute S suspended from the end of the arm 10. A transfer passage for concrete to be placed via the chute S is arranged along the supporting post 1 and the arm 10. In the concrete placing crane device, the chute includes a kneading box 20 which is hung down by its self weight and extended in the vertical direction, the kneading box 20 having a plurality of deformed passages for kneading concrete flowing down inside with its sectional shape being changed and downward discharge ports ranging to these deformed passages.
