ABSTRACT:
The invention relates to a distributor device for thick matter, especially for concrete. The distributor device (16) comprises a concrete distributing boom (18) carrying a conveying conduit (20), which has at least two boom arms (30to36) that can be swiveled about horizontal articulation axes (38to44) relative to one another or relative to a boom support (26). At least one of the boom arms, preferably the base arm (30), is telescopically movable. In order to be adaptable to the telescoping movements, the conveying conduit is assembled from three interlinked conduit sections in the area of the telescoping boom arm. A first conduit section (58) is rigidly linked with the stationary member (46), while a second conduit section (60) is rigidly linked with the extensible telescoping member (48). The device further comprises an intermediate section (62) which is connected with its ends (64, 66) to the first and the second conduit section (58, 60) and which is configured as a flexible pipe. Said pipe has a 180° arch (70) with constant bend that travels when the boom arm telescopes.
