Abstract

A method produces a mast arm with a mast arm body and with at least one pipe holder for a concrete-distributing mast for use on stationary and mobile concrete pumps with a plurality of mast arms which are connected to one another so as to be pivotable on articulated joints about an axis of articulation and which hold a concrete-conveying line which has at least one rotary joint which has an axis of rotation aligned with an axis of articulation of an articulated joint. The at least one pipe holder here has a pipe support section which serves for receiving the concrete-conveying line at a holding point which has a location predetermined by the position of the axis of articulation. The mast arm body is premanufactured with a receiving intersection and the at least one pipe holder is premanufactured with a fastening section which has a connecting intersection.
