MOBILE CONCRETE PUMP AND PRODUCTION METHOD

摘要

This disclosure relates to an automatic concrete pump comprising a support structure, which is mounted on a vehicle, for a concrete distributing mast and at least two supporting jacks which are pivotably joined to the support structure via an articulated joint, each articulated joint comprising two support plates made from a solid material, each having a bearing bore and protruding in a forked manner at a lateral distance from each other over the edge of a defining wall of the support structure, and having a hinge bolt which traverses the bearing bores. According to this disclosure, the defining wall which faces the hinge bolt is further away from the axis of the hinge bolt in the central area between the bearing plates than in the edge areas thereof which are adjacent to the support plates.

主权项

1. A mobile concrete pump, comprising:
a carrying structure fixed to a vehicle and having a delimiting wall; a support leg hinge-jointed to the carrying structure via a hinge point, the hinge point comprising two bearing plates made from solid material, each bearing plate provided with a bearing bore, the two bearing bores forming a pair of mutually aligned bearing bores, the two bearing plates projecting in a forked manner at a lateral distance from each other over the delimiting wall; and the hinge point including a hinge pin extending vertically through the mutually aligned pair of bearing bores; wherein the delimiting wall faces the hinge pin and has a greater distance from the axis of the hinge pin in a middle region of the hinge pin, between the bearing plates, than in edge regions of the hinge pin that are adjacent to the bearing plates.
