This shows the characteristic one man hose carts, which are carried on all French urban pumpers, in use. In this case, one is being used both for supply and delivery, which is okay if the runs are very short, but is otherwise a bit unusual.
The double wye on one cart has been detached; this is used if it is desired to operate two 45mm attack lines fed by a single 65mm hose.
The white drop down locker above the rear wheels contains a bundle of three 15 meter flaked preconnected 45 mm attack hoses with a variable output branch. This can be quickly deployed inside or outside a structure and is either fed directly from the pump or attached to the wye on the 65 mm hose if at a greater distance from the pump.Thi s approach is also a common feature of many pump appliances in Australia and also among some German fire services.
