ABSTRACT:
A pivotable pipe slide for use in a two cylinder concrete pump includes a swing pipe which is pivotably moved in a reciprocal fashion between the two discharge openings of the pump cylinders in such a manner that it is pressed against the discharge openings in its end positions, while it is moved away therefrom during its pivotal movement between its end positions. Pivoting is effected by means of a movable joint which is coupled to an end segment of the swing pipe and which has an axis disposed normally to the pivot plane of the swing pipe, a fixed joint spaced from the movable joint and disposed centrally between the discharge openings which also has an axis disposed normally to the pviot plane and a guide joint which is coupled to the movable joint and is pivotable about the fixed joint.
