Concrete pump pipe gate

摘要

For a concrete pump pipe gate according to Patent Application P 3045885, which comprises a concave pipe section, which on the one hand moves to and fro between two pump cylinders and on the other is coupled to a pressure line, it is proposed to shift this coupling point between distributor pipe and pressure line into the inside chamber of the hopper. This prevents concrete from escaping outside in the event of wear in the area of this coupling point. <IMAGE>
