installations of this type, there is therefore a relatively large difference in level, of the order of several metros, between on the one hand the outlet of the distributor and on the other hand the loading opening of the mixer.

  
In certain known installations mentioned above, the weighing of the aggregates and the cement is carried out by a

  
 <EMI ID = 4.1> <EMI ID = 5.1>

  
 <EMI ID = 6.1>

  
 <EMI ID = 7.1>

  
 <EMI ID = 8.1>

  
of the mixer support, carrying it by a rolling trolley

  
preferably on rails said hopper-setter is in this case still unloaded by its lower opening in the bucket of a

  
 <EMI ID = 9.1>

  
is to increase the necessary distance between the front of the device

  
 <EMI ID = 10.1>

  
itself, as a hopper for weighing aggregates and possibly cement, by resting said bucket, in its low position, on a tipping mechanism, placed below the distributor of said

  
 <EMI ID = 11.1>

  
while the hopper-setters generally have the form of funnels,

  
 <EMI ID = 12.1>

  
 <EMI ID = 13.1>

  
 <EMI ID = 14.1>

  
essentially on the one hand by the lifting movement that allas must receive along the ramp leading to the mixer, and on the other hand by the tilting movement which is communicated to them at the top of said ramp to unload them into the mixer . 8'other

  
 <EMI ID = 15.1>

  
 <EMI ID = 16.1>

  
and possibly the residual voltage of the device cable (s)

  
 <EMI ID = 17.1>

  
of the * skip * the weighing operations are consequently distorted, in a proportion which is far from negligible. Finally, the inclination

  
 <EMI ID = 18.1>

  
loading of the food processor does not reduce the penny to a minimum. haitable the distance between the front of the storage and dosing device on the one hand, and the mixer on the other hand,

  
Finally, an installation is known in which the hopper where the aggregates are discharged by the distributor, is carried below the latter, by means of running rollers, by pivoting arms, integral with a tilting mechanism, mount '

  
 <EMI ID = 19.1> <EMI ID = 20.1>

  
tilts, without being integral with it @ as well as a lifting device of the lift type, which is arranged at the foot of the mixer support so as to be able to lift the hopper vertically, keeping it straight, above the tipping mechanism on which she was resting ,. to bring its discharge opening to at least the height of the mixer,

  
One of the essential advantages of the installation according to the invention is obviously that it does not require the installation of any pit, which is of particular interest for urban sites.

  
 <EMI ID = 21.1>

  
say generally below the distributor of the storage and metering device, said tilting mechanism is ooumia no overload, which would have produced for example - by an auxiliary member fixed to said hopper, and of difficult weight the installation

  
 <EMI ID = 22.1>

  
necessary for its implantation, This advantage obviously results from the fact that the hopper is lifted vertically by the lifting device &#65533;

 <EMI ID = 24.1>

  
load it through its upper opening and unload it

  
by its lower opening, said hopper being kept upright both during its horizontal transport, by means of the mobile tipping mechanism, and during its vertical washing and unloading into the mixer,

  
By way of example, we have described below and illustrated

and dosing, and whose upper walls have openings, not visible in Figure 1, communicating respectively with the different storage sectors, and normally closed by hatches

  
 <EMI ID = 32.1>

  
 <EMI ID = 33.1>

 <EMI ID = 34.1>

  
 <EMI ID = 35.1>

  
 <EMI ID = 36.1> <EMI ID = 37.1>

 <EMI ID = 40.1> <EMI ID = 41.1> <EMI ID = 42.1>

  
 <EMI ID = 43.1>

  
 <EMI ID = 44.1>

  
It is noteworthy that the lifting movement of the hopper 10 is "trio-

  
 <EMI ID = 45.1>

  
during its lifting movement, the hopper 10 is co-operated by a lateral projection 10 'with a lever 27' integral with a chute of

  
 <EMI ID = 46.1>

  
 <EMI ID = 47.1>

  
integral for example with a leg 16 of the gantry.

  
When hopper 10 is lowered again after

  
its complete emptying, its hatch 15 is swept in the closed position while the chute 27 is returned to its ejection position.

  
 <EMI ID = 48.1>

  
It is remarkable that the distance D between the facade

distributor 1 and the frame / supporting mixer 4 may not be

  
 <EMI ID = 49.1>

  
higher loading the installation according to the invention can therefore have a relatively very small footprint, and in any case

  
 <EMI ID = 50.1>

of that previously described in particular by the means used to move the tilting mechanism and the hopper that it supports, from the distributor to the base of the mixer support, by the form

  
do the hopper, by the means provided to support said hopper ', by the tilting mechanism without one being integral with the other by the realization of the lifting device and in particular of its gripping members; one can conceive in particular to make act those:
