1 ■ "_ _# 2 ' The invention relates primarily to a method. It is on a trailer 1 of approximately 8 m in length housed for the production of concrete by means of a mobile and comprises a mixer 2, one from Mixing plant, the gravel and cement silo and a two-part cement silo 3, 4 and one Includes mixer with weighing device. : Kiessilo 5. Part 3 of the cement silo is during It is known that construction sites are lowered when the drive to the construction site is factory-made and is only there Placed concrete in the form of ready-mixed concrete with to accommodate a corresponding amount of cement, to supply so-called auto mixers, especially, preferably hydraulically, pushed up. While because the journey required to manufacture the concrete can be carried out by the silo about 61 and at the construction site borrowed machines take up about 20 tons of cement at the construction site. In addition to the cement outside the concreting time not in claim io silo 3, 4 is located at the end of the trailer to take. However, the automatic mixers require a system designed similar to a mixer feeder. relatively long unloading time, during the the construction site. In addition, they can be towed through the floor for loading, the constant transport there and back; der.Misch * For this purpose, a standard gravel tipper drives up to him machines carry a considerable dead load, ... _-._ 15 and tilts a load between 3 and 5 m ³ mixed There is also a mobile mixing plant with Ze- gravel.

In this procedure, the mixer of about 2 m height on three sides the loading however, space is needed for the gravel. drain clay. 'Ψ6ηή ^:: 4ϊτ trailer 1 with filled The invention is based on the object of bringing concrete lower cement silo 4 to the construction site, to be provided more economically than it is, especially with the 25, he initially has a supply. When one arrives Ready-mix concrete by auto mixer and the like, but cement truck from. away from home, it can be full also with the known mixing plant mentioned, if the cement is displaced in the course of the day FaIl is. The lack of space in the cities should be taken into account. However, we always think about it The lower part of the silo is also supported by the about a parking lane 2.40 m wide, when the system leaves a construction site is filled, so that be asked. with the next day- '' nagging leeway for one To solve this problem, it is proposed that there be another construction site. Since the trailer with both that in a method of the type mentioned the filled silos 3, 4 and 5 is overloaded, he will provided the system with mixing gravel or separate pERSonal '''' mn of the Site on supports ^ ". He is not tion of a desired grading curve that is not wider than the permissible parking width and can therefore half of the construction site, ζ. B. a gravel for a short time, such as a day of concreting, on plant, which is continuously supplied by trucks in this way, can be housed on the side of the road. So that is this that the gravel from the truck directly into the device is suitable for all construction sites that have a larger one The gravel silo, which can be folded down, is tipped onto the ground, requires a lot of concrete. If necessary, a from which it can be used in 40 water tankers after swiveling up the gravel silo. ΐ #

on. Particularly noteworthy is the dead load of the gravel trucks, which is limited to a minimum, compared to 1. Process for producing concrete with the ready-mixed concrete. The payload of the vehicles 45 by means of a mobile Mi & eba «hunt, the gravel and is not encompassed by the weight of large mixers or cement silos as well as a mixer with weighing device due to the cement and water content of the concrete. This reduces the transport costs that the system with mixed gravel or costs.

B. a gravel works, is also the case by load. According to the invention, the dare is continuously supplied in such a way that the gravel provided corresponds to the construction site - from the truck directly into the concrete, which is, however, tipped to a storage facility for the ground, from concrete components to the Construction site is bound. 3 - '' ■ § $, ' «■ dernier after · Köchseh ^ ehken des KiessHos in An expedient embodiment of the mobile gets the feeder bucket
