PROBLEM TO BE SOLVED: To enable a concrete bucket device to easily and accurately make landing and falling-down works while the hanging weight of the device is reduced. SOLUTION: The main body 1 of a concrete bucket device which is hung down by means of a crane after ready mixed concrete is put in the main body 1 is separated from a stand 2 which is set up on the ground, etc., so that only the main body 1 may be hung down when the main body 1 is moved in a hung- down state or the concrete is placed. In addition, the main body 1 is rotatably supported by putting a supporting pin provided to the main body 1 in the pin receiving recessed section 33 of the stand 2 so that the main body 1 may change its attitude between a hung-down attitude and a fallen-down attitude. Therefore, the landing work of the concrete bucket device is stabilized while the hanging- down load is reduced and, in addition, the device can easily and accurately make falling down work and raising work.
