Claims

[Claims for Utility Model Registration] A swing tube is provided at the bottom of the hopper, and a swing operation shaft of the swing tube is connected to a piston rod of a drive cylinder via an operation lever. In a concrete pump in which the swing tube is swung by a predetermined swing angle by an expansion/contraction operation to switch the flow path in the hopper, the mounting shaft portion of the swing operation shaft to which the control lever is detachably attached is as follows: A concrete pump characterized in that it is formed into a rectangular shape with a cross-sectional pressure of (360' x n) (θ: swing angle, n: arbitrary positive integer of θ).
