• At least one of the axles of the wheels is provided with a freewheel-type anti-back-up system, in order not to risk the recoil of the washing trolley during operation, a return likely to occur. to intervene by reaction to the thrust exerted by the jets under high pressure emitted by the nozzles of the washing head.
• the non-propulsive wheels of the washing trolley are mounted oscillating, in particular with respect to a central hinge axis, thus making it possible to confer on the trolley a certain adhesion to the ground, in particular in the case of passage of 'obstacles.
• the invention also relates to a more complex washing system implementing the aforementioned washing carriage.
• This washing system incorporates in addition to a washing trolley of the type previously described, a frame movable in translation and height, and provided with leveling ramps of said frame with the cabin or the enclosure to be cleaned.
• This chassis includes also the liquid tank (s) implemented by the washing trolley, as well as channel-type connection means with the washing head, in addition to the means of unwinding and automatic winding of these means and a high pump pressure or a compressor, suitable for conveying the liquid or liquids at the nominal pressure at the nozzles of the washing head.

• FIG. 1 to 4 shows a washing trolley according to the present invention.
• this washing trolley is more particularly intended to ensure the washing and disinfection of a refrigerated box of a truck or a semitrailer.
• the invention can not be limited to this single application and that, since it is appropriate to proceed to the cleaning of an enclosure, whatever its shape and since it is provided with a substantially flat base, suitable to allow the progression of the washing trolley, the latter of application.
• This carriage (1) basically comprises a frame (2) provided with wheels respectively front (3, 3 '), and rear (4, 4'), intended to allow its progression within the cabin, and generally the enclosure considered.
• the front wheels (3, 3 ') are motorized respectively by means of an electric motor (14) and (15), the operation of which is ensured by means of rechargeable batteries or generators (not shown ).
• the rear wheels, non-propulsive (4) and (4 ') connected to the frame by hubs (12) and (12') are mounted oscillating, that is to say that the hubs (12) and (12) ') are articulated at a hinge pin (13) formed within the carriage (1), to allow the latter to maintain the adhesion to the ground in case of passage of obstacles, such as in particular waste that may still be in the cabin when it is cleaned.
• the front wheels (3) and (3 ') are provided with an anti-recoil system, constituted respectively by an axis (16) integral with a free wheel (17). This prevents unwanted undesired retraction of the truck during the cleaning or washing phase.
• This freewheel system is disengageable, for example by reversing the direction of rotation of the motor shaft, to allow the carriage to retreat when the washing step and / or disinfection is complete.
• the front face of the carriage is provided with a rotating washing head (7) provided with a certain number of nozzles for ejecting the washing and / or disinfecting liquid.
• This washing head is rotatably mounted in an angular variation of 360 ° on a support (6), itself mounted at the end of a rod (5) reversibly secured to the front face of said carriage.

• the washing head comprises a rotating part, consisting of a peripheral ring provided with eight nozzles distributed equidistantly relative to each other and substantially contained in a vertical plane.
• this plane is slightly inclined towards the front of the washing trolley of fifteen degrees, in order to promote the performance of the rinsing step.
• This rotating part of the washing head is indeed intended to ensure the rinsing of the box or container, and therefore after a washing step and / or disinfection.
• the rotation of the washing head allows the jets emitted by the nozzles which it is equipped to reach all the places of said cabin during rinsing. Indeed, in its basic version, this rotation is preferably inscribed in a plane perpendicular to the direction of progression of said carriage. However, it is important that this rotation is recorded or occurs in one or more planes perpendicular to the surface of the truck floor to be cleaned.
• the support (6) of the rotary head (7) is itself capable of being driven by an angular rotation movement of 180 °. This rotation occurs this time along a plane parallel to the base of the enclosure to be cleaned. It is for example made by means of an electric motor (18), operating on a rotary cam (19), connected by means of a connecting rod (20) to the base (21) of the rod (5). .
• the 360 ° rotation of the rotating head occurs in a plurality of planes perpendicular to the ground of the truck to be cleaned.
• washing and / or disinfection itself are also provided by the washing head. But during this or these steps, the liquid is conveyed at a lower pressure, so that there is no effective rotation of the head in the vertical plane.

• This frame can even be self-propelled. In other words, this frame can be mobile in translation and height.
• This lifting platform is intended to receive, on the one hand, the elements necessary for the operation and supply of the washing trolley (1) in fluid (s) under pressure, and on the other hand the trolley itself ( 1), as can be seen in Figure 5.
• the free end of this platform (26) is provided with hinged connecting arms (27) allowing, once the lifting platform (26) is substantially level with the floor of the cabin and generally of the enclosure to be cleaned, to be folded to allow the progression of said washing trolley (1) within it.
