CONCRETE TRANSPORT AND PLACING DEVICE

PROBLEM TO BE SOLVED: To provide a concrete transport and placing device allowing heightening of the bucket moving speed in the radial direction in the works. SOLUTION: A concrete transport and placing device is equipped with a mast 20 consisting of a plurality of mast segments 3 stacked one over another, an elevation frame 5 capable of rising along the mast 20, a revolving frame 6 installed on the elevation frame 5, a jib 21 protruding approx. horizontally from the revolving frame 6, and a trolley 22 capable of moving transversely along the jib 21 and hanging a concrete transporting bucket 9 with the possibility of rising and falling, whereby the moving speed of the bucket 9 in the radial direction in the works is heightened by a transverse motion of the trolley 22.
