Emergency vehicles must reach their scene reliably and safely, even in the event of large-scale fires in difficult terrain.
More and more summers with record heat and weeks of drought: forest and vegetation fires pose special challenges for fire brigades worldwide. With the new MAN TGM 18.320 4x4, MAN is offering a chassis for firefighting applications in the highest off-road category in accordance with DIN EN 1846-1 for the first time. The 18-tonne chassis with permanent all-wheel drive is specially designed for operations off paved roads. Special protective measures and equipment prepare the vehicle specifically for operations in forest and vegetation fires. With its high payload of up to 11.5 tonnes, tank firefighting vehicles with up to 6000 litres of extinguishing water and 500 litres of foam concentrate plus standard equipment can be built on the MAN TGM 4x4 chassis.
The vehicle is powered by a 320 hp engine. Power is transmitted by the MAN PowerMatic automated transmission. The individual 14.00 R20 tyres on the front and rear axles support off-road capability. Depending on the body and cab variant as standard or double cab, different wheelbases and crew concepts can be implemented.
For operations near sources of fire, the chassis has a special heat protection device. Air, electrical, AdBlue and fuel lines are designed in such a way that they can withstand a temperature of up to 130 degrees Celsius for a period of ten minutes. In addition, there are mechanical protective measures for particularly exposed vehicle components.
A hinged roof hatch between the driver's and front passenger's seats opens up additional application possibilities. A height-adjustable tread surface makes it easier to use the hatch and supports the crew when observing the surroundings or working from the cab. Even with the roof hatch, the cab meets the latest ECE R29-3 crash test standard in order to provide the occupants with the best possible protection, even in the event of serious accidents.
The vehicle concept also enables extinguishing while driving according to the "pump and roll" principle. This allows the crew to fight fire areas along paths or during slow off-road driving.
One of the key features is a tyre pressure control system that can be controlled from the driver's workplace. This allows the driver to adapt the tyre pressure to different surfaces and operating conditions. The system is supplemented by a tyre pressure monitoring system and run-flat tyres. These make it possible to move the vehicle out of a hazardous area in a controlled manner, even if the tyre is damaged. With its water passage capacity of up to 950 millimetres, the vehicle can also be used on flooded roads and farm roads.
The high level of off-road capability is supported by further technical adjustments. These include a mechanical protective cover for the transfer case and an exhaust tailpipe raised behind the driver's cab. At the same time, the optimised entrance situation makes it easier to access the crew compartment. The extensive modifications to the TGM 4x4 were implemented by MAN Individual in cooperation with ESTEPE, the specialist for cab modifications and chassis adjustments.
With the new MAN TGM 18.320 4x4, bodybuilders and fire brigades have a versatile basis for vehicles for forest and vegetation firefighting. The concept combines a high level of off-road capability with special protective measures and flexible options for cab, crew and body. Source
