PURPOSE: To permit the light use in a narrow site by mounting a turning mechanism which supports a hopper and a screw conveyor in turnable manners onto a base and permitting the base to be mounted onto the fork of a forklift.

CONSTITUTION: The main members are constituted of a hopper 10, screw conveyor 20, and a turning mechanism 30, and a base can be loaded onto a fork F1. Further, a cylinder 24 is arranged in the lower part of a trough 21, and the conveyor 20 is shifted in the longitudinal direction for the hopper 10 by the extension and contraction of the cylinder 24, and a pinion 33a is meshed with a rotary member 32 fixed onto a base 41. The base 41 is loaded onto the fork F1 and traveling-shifted to an arbitrary position, and the rising and lowering of the fork F1, horizontal turn of the turning mechanism 30, and the extension and contraction of the conveyor 20 are carried out, and a discharge tongue piece 21a is set oppositely to a prescribed feeding position, and concrete is fed. Therefore, the light use in a narrow site, etc., is permitted.
