Right from the outset the Mercedes Zetros was developed primarily for off-road use. Unlike many utility vehicles that are intended to perform various jobs, with both on-the-road and all-wheel-drive versions, similarly to the Unimog, the Mercedes Zetros is uncompromising in its design. The version with the over-engine driver's cab does take up a little loading space, but brings a few advantages when it comes to maintenance and operation. Whereas the military, but also explorers, didscovered the advantages of the Zetros long ago, use of the heavy off-road truck by fire services is still an absolute exception to the rule.
A team cabin for the Zetros
Based on the Zetros, Paul Nutzfahrzeuge has developed a special model for use by fire services, which could end the wallflower existence of the Zetros when it comes to use by emergency services. With the team-compatible four-door cabin, among other new features, which offers space for a six-man fire team. The special fire-fighting vehicle with tank is designed on the basis of the Mercedes-Benz Zetros 1833 A 4x4 for fire fighting in forests and open spaces. For this purpose, it was commissioned by the FFW Filderstadt under the name Florian Filderstadt 4/29.
In order to transport the cab for the six-man crew, the driver's cab has been extended by 700 mm. It has been fitted with LED lighting throughout, auxiliary heating and a rear-facing seating bench with individual cushions, headrests and three-point safety belts.Underride protection and heat insulation
The forest fire equipment includes bullbars on the front, a branch deflector above the cabin, various protective brackets on the lighting equipment and a special folding step at the back. The heat insulation, including the insulation of the electrical and pneumatic lines on the frame and axles have been mounted with stainless steel brackets. All important units such as the engine, fuel tank and compressed air tank are protected against damage from tree stumps or bushes, by means of metal plates. The official wading depth is 80 cm and thus enables use in the event of high waters.
Thanks to the automatic transmission, the fire service Zetros can be operated without any problem, with snow chains ensuring safety on smooth road surfaces. The S-TLF is fitted with a 14 kVA generator, a light kit, 2 motorised chainsaws, a submersible pump, a waste water pump, a 50 kN hydraulic winch, equipment for forest fire-fighting, a front-mounted spraying system and a roof hatch with a fog nozzle for pump-and-roll operation.
