The motor 6 is supported by an auxiliary column 7 and a horizontal rail 8 incorporated in the frame 1, and the screw 5 is driven via, for example, a chain or a V-belt 9.

[0007] Reference numeral 10 denotes a detachable hanging support rod.
It is provided so as to penetrate the upper horizontal rail 1b. 11 is a ladder, 12a. Reference numeral 12b denotes a caster provided at each corner of the frame 1 or at a lower portion of the frame near each corner. The caster 12a on the side near the discharge port 4 of the hopper 3 is of a freely changeable type, and the other casters 12b are in the direction. It is provided in a conversion fixed type. Reference numeral 13 denotes a safety panel attached to the support plate 14 of the frame 1, which is electrically connected to the motor 6, and which operates when an abnormal load is applied.
The motor 6 is configured to stop automatically.

In the concrete bucket thus constructed, a predetermined amount of low-slump concrete is stored in the bucket body 2 and transported in a suspended state to the concrete placement position, and the motor 6 is driven at the placement position. By rotating the screw 5, the concrete is transferred to the tip 3 b side of the hopper 3, and the concrete is sequentially discharged from the discharge port 4 and poured. In this case, hopper 3
Are located in the lateral direction, there is almost no leakage of concrete in the middle of transportation, and even if the communication opening 2a between the bucket body 2 and the hopper 3 is relatively wide, even concrete of low slump can be used. Screw 5
Thus, the hopper 3 can be efficiently transported to the tip 3b side of the hopper 3, so that there is almost no leftover concrete in the bucket body 2 and waste of concrete is eliminated.

Further, even if the concrete casting position is near a wall surface or a columnar object, since the concrete discharge port 4 is located on the tip 3b side of the hopper 3, no other guide gutter or the like is required. The concrete can be supplied directly from the discharge port 4 to the casting position, and the bucket body 2 and the hopper 3 are disposed in a housed state inside a box-shaped or tower-shaped frame, and the surroundings are protected by the frame.
