Problems solved by technology

On the other hand, it has to be taken into account that the support structure including the rod seat is a very large and heavy welded structure, which can only be manipulated with great effort, for example, to carry out a tightness check
Possible leaks during this inspection can only be sealed with difficulty if the joint is located inside the rod seat

Embodiment Construction

[0016] exist figure 1 and 2 The mobile concrete pump shown in has a commercial vehicle body 10 with an engine-driven chassis 12 and a driver's cab 14 , the engine drive of which is coupled via a drive train 16 to a rear axle 18 . The commercial vehicle chassis 10 carries a concrete pump 20 which is connected to the running gear 12 via a structural frame 22 . The concrete pump structure mainly comprises a main pump 24 with two hydraulic drive cylinders 26 , two delivery cylinders 30 connected in pairs to the drive cylinders 26 via a water tank 28 and one other rigidly arranged on the delivery cylinders 30 Material output container 32 on the end. Furthermore, the structure comprises a pressure feed line 34 which is guided by a distribution boom 36 configured as a bent rod and has at the end of the last boom arm a not shown outlet for the concrete to be poured. end hose.

Abstract

The invention relates to a mobile concrete pump comprising a supporting structure (46) that can be placed directly or indirectly by means of an assembly frame (22) on the running gear (12) of an HGV chassis (10), for receiving functional units that form a support device (38) and a placing boom (36). The placing boom (36) is rotatably mounted on a boom pedestal (44) that is integrated into the supporting structure (46), while the support device (38) comprises two telescopic tubes (54, 56) which are integrated into the supporting structure (46), cross over one another at different heights and have diagonal passages that are open at the front. A respective open space (60, 62) in the supporting structure (46) lies below the upper and above the lower telescopic tube (54, 56), each open space being separated from the neighbouring telescopic tube by an intermediate base (58). A feature of the invention is that a pre-fabricated liquid tank (70) is inserted into at least one of the open spaces (60), the outer contour of said tank being geometrically adapted to the supporting structure (46) and said tank supplementing and reinforcing the supporting structure (46).

Description

technical field [0001] The invention relates to a travelable concrete pump with a support structure, preferably constructed as a welded structure, which can be mounted directly or indirectly via a structural frame on the running gear of a commercial vehicle chassis, and has a structure forming a distribution boom by accommodating the support device Functional unit in which the boom is rotatably supported on a pole seat integrated in the support structure, said support device comprising two integrated in the support structure, diagonally open forward, intersecting each other at different heights and the support structure has a free space below the upper telescopic tube and above the lower telescopic tube, respectively, separated from the adjacent telescopic tube by the intermediate floor. Background technique [0002] In a mobile concrete pump of this type (DE 102 46 447 A1), the support structure is mounted on a structural frame and is mounted together with the structural fr...
