Yoke-shaped abutment for the tube switch of a concrete pump

摘要

In an apparatus for concrete conveyance or concrete distribution, from a funnel into a pressure line by means of a tandem piston pump, the distributor is "floatingly" supported in the region of the transition to the pressure line by means of an external abutment, connected to the end of the distributor, and is pressed by means of a cylinder-piston unit against the concrete conveying piston in a manner dependent on the concrete conveying pressure. The apparatus is used in particular in the case of self-propelled concrete pumps. <IMAGE>
