The use of the supporting frame is preferably provided for a concrete pump with a dispersal pole, which is installed on a lorry chassis. The main feature of this supporting frame consists in the fact that the connection from the substructure of the rotary column to the rear support takes place by means of two connecting members which, as was previously customary, are not connected over the entire length of the longitudinal members of the lorry chassis but rather extend backwards, free from the substructure of the rotary column, as far as the greatest admissible vehicle width (2.50 m). As a result, the following advantages are obtained: a) the locally induced operating forces of the rear support are substantially smaller than in designs with connecting members which extend at a small distance (approximately 0.90 m) from one another on the longitudinal members of the lorry chassis (U-profiles), b) the longitudinal members of the lorry chassis are thus no longer loaded by operational forces of the support and, with the auxiliary frame which also consists of U-profiles, can remain easily rotatable over almost their entire length, which is a design aim in lorries; c) all the substructures can be attached to the connecting members or to the supporting bar of the rear support and thus do not restrict the freedom of movement of the longitudinal members of the lorry chassis; d) the connecting members can be used as containers for holding fluids; e) the entire structure can be completely premounted in a vehicle-independent manner. <IMAGE>
