The bar of the T which extends perpendicularly to the leg forms a pull handle that the operator can grip to pull and direct said device.

The tooling system 10 is able to be fixed to the device by being placed along the bottom bar of the U (FIG. 12) and / or is able to be fixed to the device by being placed along the leg of the T (FIG. Figure 11). Thus, the tooling system according to the invention takes into account the ergonomics of carrying by integrating on the reel. When the reel is not present or when it is not present on site, the tooling system can be attached to other similar equipment, such as a motor pump or booster. This tooling system can thus be fixed or secured on various supports intended to be deployed by firefighters. Said support then carries the tooling system in place of the firefighter. Thus the tooling system according to the invention replaces several tools with useful features for the speaker. In the example illustrated in the figures, the support is a reel but the support, as explained above, may be quite different. As explained above, a number of removable or fixed accessories can be integrated on the bar of the tooling system so as to replace the other independent tools hitherto used by the speaker. The present invention is not limited to the embodiments described and shown, but those skilled in the art will be able to make any variant within its spirit.

Additional elements can equip said bar of the system. These additional elements can be attached as soon as the bar is made or can simply be added to the bar depending on the desired use to make the tooling system even more versatile in the field. The additional elements can equip the bar definitively (welding, gluing, etc.) or be removable (pins, straps, magnets, etc.). The attachment means of the additional elements on the bar of the system may be of the same type as those used to fix the tooling system on its support. Advantageously, the option attached to said tooling system may be a maneuvering square linked to the bar of said tooling system by means of a ball pin so that the maneuvering square is well positioned on said tooling system. tooling. The tooling system may also be provided with a second square at another location so that the user can optimize his actions during his intervention. The ergonomics of the system makes the user's gesture more efficient and faster. For example, when a firefighter has to use an emergency fire hydrant equipped with a locking device installed in his outlet, he can carry out the following operations: open the trunk of the post fire if the post has such a trunk, -use the operating square (s) of the tooling system to open and remove the plugs positioned on each corresponding socket of the post, 30-if appropriate, extract the blocking device of the post using the tooling system as a lever arm with the ultimate tear-off key, replace the flywheel to manipulate the maneuvering square of the hydrant.

Preferably, the system is provided with two operating squares positioned on the multi-purpose tooling system so as to be able to better manipulate the rotation of the plug of the socket, in order to make the tool more ergonomic, more efficient and faster for its user. especially when it operates in a narrow place where there is no room. This system meets the needs for speed of use, ease of use and intuitive handling. The removable elements of the system may be provided with identification means. These identification means may be visual, such as numbered and / or electronic marking, such as an RFID chip, preferably provided on the soleplate, which makes it possible to limit the risk of degradation of the means of identification. .

When the tooling system equips all-purpose vehicles (VTU) firefighters, for example van-type, this type of vehicle is not equipped with reels. A support, such as a rack, which fixes the tooling system is then directly installed on the structure of the vehicle itself.
