PURPOSE: To transport matter with heavy load such as concrete not hardened smoothly and positively to high ground from low ground, by forming a screw body and transport pipe itself in bending-free shapes.

CONSTITUTION: One screw body 5, which can freely be bent, is made up in such a manner that bosses 3, on which outer circumferences spiral grooves 4 are notched at proper intervals, are fastened to a wire rope 1, rectangular sheets 2 as stainless steel are twisted and inserted and fast sticked to the grooves 4 and the both end portions of each sheet 2 are welded. The screw body 5 is inserted into a transport pipe 6 in synthetic resin, which is similarly manufactured in a bending-free shape, in a rotation-free form, and the one end portion is connected to a driving shaft 8 of a drive means 7. Thus, no obstacle is constituted because screw body itself coincides with the bending of the transport pipe and can freely be bent even if the revolution of the screw body 5 curves the pipe 6. Consequently, concrete not hardened, etc, charged from a hopper 9 can be conveyed smoothly and positively.
