Building site shaft mounted concrete distributor - with cables cardanically linked to trunk base as suspension elements

摘要

The device, for concrete distribution in the course of building operations, comprises a concrete shaft, made by the sliding process, with a swivelling jib arm, and a trunk, projecting into the shaft and supported on two opposite sides of it. This is suspended, for vertical load accommodation, on transverses connected by sliding blocks to the climbing rods set in the shaft concrete. The suspension elements (14) for this are in the form of cables, cardanically joined to the carrier trunk (5) in the base area (18). The carrier trunk is braced against the inside walls of the shaft by roller blocks (16) with rollers (17). Deflecting rollers may be provided, to bring the cables together into an end continuous length of cable.
