The support frame is a steel structure that serves essentially to attach to the tractor, secures the water storage tank and the drive. As the Fire Extinguisher was designed for continuous use, it was an important consideration during the design to ensure that the support structure was as robust as possible, withstands long-lasting, increased stress, vibration and other major mechanical influences. The lower link points on the back of the bracket allow the FIELDS FIREMAN H1-650 Extinguisher to be attached to the lower link of the tractor and then secure the top link to the third link of the tractor. There are four feet at the bottom of the base frame. Above the base is the cradle where the tank is located. Starting from the cradle, two bent steel straps also help secure the container. Also starting from the base part, the bent support structure in the middle part thereof serves for the three-point attachment.
A cylindrical, hot-dip galvanized steel tank, 700 mm in diameter, is used for storing or transporting water. At the top of the tank there is a STORZ C filling nozzle through which the tank can be filled with water. In addition, there is an air vent through the top of the tank. The opening at the bottom of the tank has a bayonet hose connector with a stopper that is suitable for both filling and emptying the tank. On the right side of the tank there is a transparent plastic hose, the water level indicator tube, which defines the tank in a semicircle.
The central gear unit is a unit consisting of a hydraulic motor and a water pump connected to it. With the help of a control valve, the amount of water and the pressure of the water can be regulated.
A 20 m D25 shaped fire-retardant fire hose is attached to the tank and has a variable spray jet in accordance with D25 EN 671. In the transport position, the hose is wound on the container, which is secured to the container with 4 hose clamps. In use, the rubber straps can be removed in one step and the hose can be unwound.
