The invention relates to a mobile working device, in particular of concrete pump, which includes the chassis, two front and two rear support console, nominated from transport position and at least one working position relative to the undercarriage and is based each using the supporting feet on the ground when lifting the chassis, and the drive unit to control the working units and/or reference consoles.

The mobile concrete pumps operating units include, in particular, mast stand, equipped with a distribution mast, and Central pump, equipped with the capacity to download the material. Central pump flows into the discharge line, which is laid over a distribution mast. Depending on the pump model, the drive unit includes one or more hydraulic pumps and other auxiliary pumps, for example, to drive the stirrer in the vessel for loading of the material of the Central pump. Support console primarily have the task reliably and without tipping over to rest of the working device in the working position on the ground in all positions of the operating units. Accordingly, the strength requirements for supporting the consoles are relatively high. For their manufacturing are usually applied massive beam profiles or hollow chambers�s profiles from steel. On the other hand, the support console is on the undercarriage a lot of space due to the effective loading area.

On this basis, the basis of the invention is to perform at least a portion of the support consoles lighter while retaining strength and stability, and to provide additional function, saving space.

To solve this problem is proposed a combination of the characteristics specified in claim 1 of the claims. Preferred embodiments of and improvements of the invention are contained in the dependent claims.

The present invention, the decision was based on the idea that at least one beam having or hollow-chamber profile reference consoles may be provided with a transverse aperture. Especially preferred was, if in each of the rear support consoles with at least one transverse opening. Due to the transverse aperture, the first, the saving of material. Secondly, the transverse opening with your walls of an aperture in the support console performs the function of stiffening.

One of the preferred embodiments provides that at least one transverse opening is made in the form of an open on one or both sides if necessary, be closed by the housing cover. In this case mo�em to be for example, an auxiliary unit of the drive unit. The auxiliary unit is preferably made in the form of a hydraulic radiator predominantly hydraulic drive unit. Through hydraulic lines, hydraulic hoses and/or cables it can be connected to a fixedly mounted on the chassis Central office or a drive node. Another added feature can be achieved due to the fact that at least one is made in the form of a hollow chamber profile and having a transverse aperture reference consoles is formed by the hollow chamber tank for liquids.

According to another preferred embodiment of the invention partially provided with transverse openings of the support console and working units are located on the mounting frame fixedly mounted on the undercarriage.

Below the invention is explained in more detail on one example implementation, the schematic image shown in Fig. Shown:

Fig.1a and b is a visual representation of concrete pump, equipped with an inside retractable and fold-out rear bracket;

Fig.2 is an illustrative side view of the rear support console has a built-in in the transverse aperture of the auxiliary unit.

Shown in Fig.1a and b mobile concrete pump �has the chassis 10 of the truck with the supplied motor drive chassis and the cab 14 of the driver. The chassis 10 is mounted concrete pump 20, which is connected by means of the mounting frame 22 to the chassis 12. Design of concrete pump comprises essentially a Central pump 24 with two hydraulic pressure cylinders 30 and is rigidly mounted on the free end of the injection cylinder 30 with a capacity of 32 to download the material. In addition, this design includes a discharge pipe 34, which is laid through is made in the form of an articulated mast junction of the mast 36. Distribution mast 36 is mounted for rotation around a vertical axis rigidly connected near the cabin 14 of the driver with the mounting frame 22 of the bearing housing 44 of rotation of the mast. At the rear end of the mounting frame 22 is support 46 of the mast that supports the distribution mast 36 is depicted in the retracted position of the movement. In addition, provided support device with exposed front and rear consoles 38, 40. When concreting the support console exposed, as shown in Fig.1b, and when lifting the chassis 12 with its telescopic support legs 42 rest on the ground. The hydraulic drive of the Central pump 24, the junction of the mast 36 and the supporting consoles 38, 40 is carried out by means of the drive unit 47, essentially consisting of a hydraulic pump and over cap�, which can be driven coming from the engine of the vehicle transmission.

A feature of the invention lies in the fact that both console rear support 40 is made in the form of hollow chamber profiles, which in its front region are the transverse aperture 48 with a circumferential wall 50 of the opening. In this case the transverse aperture 48 performs the function of reducing weight and the function of increasing the rigidity. In the right console rear support 40 of the transverse aperture 48 forms a housing in which is an auxiliary unit 52, which, for example, by hydraulic lines, hydraulic hoses and/or cables connected to the drive hub 47. Auxiliary unit 52 made of, for example, in the form of a hydraulic radiator. In the example shown the implementation containing the hydraulic radiator transverse aperture 48 with one side opened inward, and the outer side is closed by a cover 54. In principle, one of the transverse openings 48 can also be used as extra Luggage, for example, space for tool boxes, hitches, wooden boards or the like.

In summary, the following can be stated: the invention relates to a mobile working device, in particular of concrete pump. The working device comprises essentially a chassis �part 12, two front and two rear nominated from transport position and at least one working position relative to the chassis 12 and is based each using the base 42 feet on the ground when lifting the chassis support console 38, 40 and the drive unit 47 to control the working units and/or reference consoles.
