ABSTRACT:
The disclosure relates to mobile concrete delivery devices and similar heavy equipment, which includes a plurality of carrier arms which can be moved or swung with respect to one another. Along the carrier arms are provided conduits or pipes of a concrete distributing apparatus. At the terminal carrier arm an output unit is arranged which is comprised of an additional carrier arm and an additional concrete conveying conduit. The output unit is connected in such a way that in its rest position it extends parallel with respect to the terminal carrier arm. The output unit is adapted to adjust itself when it assumes the operating position to assume a tight coupling position with respect to the terminal carrier arm and the associated concrete conduit. The apparatus makes it feasible to enhance the longitudinal reach of the concrete delivery apparatus by the length of the additional carrier arm without requiring substantial additional efforts for the installation thereof.
