the figures from 39 to 68 represent the positions and the possible transport conditions of the embodiments according to the figures from 9 to 38.

 Referring to the drawings, it can be seen that the installation according to the present invention comprises a base unit and one or, preferably, several complementary units easily associable with the base unit and interchangeable with each other through some very simple mechanical assembly operations, for which these same units have been carefully arranged, for example with housings, holes for bolts and pins, supports and so on.

 In the version shown in Figure 1, the basic unit according to the invention comprises a robust metal frame 2 on which are mounted in a stable manner a balance for inert loads 3, a metering device for inert loads 4, a conveyor belt extractor for inert loads 5, a doser for cement 6, a scale for cement 7 and an electrical control device 8.

 Figure 2 shows the basic unit of Figure 1 equipped with a concrete mixer 9.

 In the version represented in FIG. 3, the base unit 1 ′ of the installation according to the invention always comprises the elements which constitute unit 1, but it comprises a shorter conveyor belt for inert loads 5 ′ for make way for the structure 10 of a loading bucket 11 with which it is compulsorily equipped. Furthermore, the cement dispenser 6 and the cement scale 7 are located on the support plane 12 of the cement mixer 13 which equips this same unit.

 Figures 4 to 8 illustrate in detail some examples of complete installation according to the invention.

 The first of these figures shows, in the working position, a dosing and concreting installation obtained by combining with Base Unit 1 already described a storage hopper for inert loads of the type with three compartments in line, indicated with the reference 14, and a silo with cement indicated with reference 15, the installation also comprising a concrete mixer 9.

 FIG. 5 shows on the contrary in the transport position an installation according to the invention produced by associating with the base unit 1 already described a loading group for concrete mixers 16 which is shown in the folded position and which is constituted by a conveyor belt 16 'for inert loads and by a 16 "conveyor screw for cement. The basic unit 1 of this installation was equipped with an axle 17 fitted with wheels 17' and with a braking system, so that all the installation can be easily transported by a road tractor 18 for which it constitutes a real semi-trailer.

 It is on the other hand on a normal semi-trailer 19 that the road tractor 18 of FIG. 6 transports the version of the installation shown in this same figure, in a folded position for transport. This installation consists of the base unit 1 'already described, equipped with a cement mixer 13 and a loading bucket 11, as well as by a ground storage group with device for feeding inert loads of the bucket type. scraper, indicated with the reference 20 and folded in transport position on the frame of the unit 1 '.

 Figures 7 and 8 illustrate in detail and in the working position two other types of metering and concreting installation according to the invention. In the embodiment of FIG. 7, the installation comprises the base unit 1, the cement silo 15, the concrete mixer 9 and the scraper bucket device 20. On the other hand, in that of FIG. 8, still based on the use of the base unit 1, the concrete mixer 9 is replaced by the loading group for automobile concrete mixers 16 and the scraper bucket device by a scraper spoke device 21.

 According to the fundamental characteristic of the invention, it only takes a few operations to switch from one type of installation to another, quite simply by replacing the complementary units on the base unit by dismantling and mechanical assembly which can be carried out. even on site, so as to adapt the installation to the different requirements that may arise over time.

 In this regard, it seems appropriate to give a practical idea of the very vast possibilities offered by the installation according to the invention to users by referring to the very numerous attached figures which, for the sake of space, have been executed on a reduced scale. and which show on the one hand (Figures 9 to 38) the most interesting possible combinations between base unit and additional units for making dosing and concreting installations capable of meeting any work requirement and, d 'another side (Figures 39 to 68) the different ways in which it is possible to transport these same facilities, with full respect for the size of the road, using a tractor unit.

 A detailed description of all these figures seems entirely superfluous after the essential elements which make up the installation according to the invention have been defined, since only their combination varies from one figure to another. Furthermore, the experienced technician would have no difficulty in interpreting the very clear, although synthesized, representation of the various solutions studied and developed by the applicant.

 Although numerous embodiments of the invention have been described and illustrated, as well as possible variants thereof, it goes without saying that other embodiments according to the invention are always possible without however go beyond the scope of the claims which follow.
