Fire engines on truck chassis: EN 1846 classes, ladders, the chassis and the body builders

A fire engine — in the words of the standards, a firefighting and rescue service vehicle — is in most cases a truck chassis with a body that carries the crew, a pump, water and foam, equipment lockers or an aerial ladder or platform. Europe sets the requirements for the vehicle in the EN 1846 series and for aerial appliances in EN 14043, EN 14044 and EN 1777. The chassis itself is left to the truck makers: EN 1846-2 assumes a finished standard truck chassis and sets no requirements for it. This page sets out what the standards cover, how national rules in Germany and Türkiye build on them, and what chassis makers and body builders publish. It does not rank or recommend any of them.

EN 1846: classes, categories and common requirements

EN 1846-1:2011, Nomenclature and designation, sorts every vehicle above 3 t by its gross laden mass (GLM) into three classes — Light (L) above 3 t up to 7.5 t, Medium (M) above 7.5 t up to 16 t, and Super (S) above 16 t — and by its road and off-road ability into three categories: 1 urban, normally used on constructed roads and commonly with one driven axle; 2 rural, able to use all roads and limited off-road surfaces; and 3 all-terrain, able to go cross-country and commonly with all axles driven, differential locks and single tyres. The 2011 edition changed the class limits; the DIN type list notes that class M ended at 14 t until July 2011. CEN decided in 2024 to confirm the 2011 edition rather than revise it.

EN 1846-2:2024, Common requirements — Safety and performance, published in December 2024, supersedes the 2009+A1:2013 edition. It treats the finished standard automotive chassis as safe for its transport functions within the limits set by its maker and sets no requirements for it. It covers vehicles for use between –15 °C and +40 °C and leaves out vehicles of 3 t or less, ambulances, PTO-driven removable equipment not used for firefighting, and airport vehicles within the recommendations of the International Civil Aviation Organization. It defines the gross laden mass as the unladen mass plus 90 kg for each crew member with personal protective equipment, a further 15 kg for the driver’s protective equipment, and the extinguishing agents and equipment carried; the permitted maximum, the PTLM, is the gross laden mass the chassis maker declares. The general difference between actual and permitted weights is set out in truck weights: GVW and GCW. The 2024 edition adds requirements for a rollover protective structure (ROPS) for the cab and renames a clause “Energy storage and range”.

EN 1846-3, Permanently installed equipment — the water installation, liquid additive installation, monitor, equipment gantries and demountable systems using a hydraulic hook arm — is in force in its 2013 edition, for ambient temperatures of –15 °C to +35 °C. A revised edition was ratified by CEN on 24 August 2026 and was planned for publication on 13 October 2026; it extends the temperature range to +40 °C, covers wireless control systems and adds clauses on lifting systems using a crane and on extendable equipment.

Ladders and platforms

Turntable ladders follow EN 14043:2014 when their movements can be combined and EN 14044:2014 when they run one after the other. Both define classes 18, 24, 30 and above 30 up to 56, the class being the value equal to or immediately below the nominal rescue height, and apply in winds on the ladder of up to 12.5 m/s. CEN decided in January 2026 to revise EN 14043; we found no draft. EN 1777:2010 covers vehicle-mounted hydraulic platforms and is to be used together with EN 1846-2 and EN 1846-3.

Machinery law and type approval

EN 1846-2:2024 became a harmonised standard under the Machinery Directive with Implementing Decision (EU) 2025/1740 of 13 August 2025; the deletion of older references in that decision applies from 20 January 2027, the day the Machinery Regulation (EU) 2023/1230 starts to apply. CEN lists the revised EN 1846-3:2026 under that Regulation.

In EU type approval, Regulation (EU) 2018/858, as published in 2018, does not count fire engines among its special purpose vehicles; they appear among the two-digit supplements to the bodywork code of an N-category vehicle as “31 Fire engine”. The same list gives refuse collection vehicles the digits 18 and concrete mixers 15; see refuse collection vehicles and truck mixers and concrete pumps. Tippers have the digits 10; see tipper trucks.

National types: Germany and Türkiye

In Germany, the DIN 14530 series defines the vehicle types on top of EN 1846. Its type standards give the LF 10 and HLF 10 an engine-driven centrifugal pump of 1,000 l/min and the LF 20 and HLF 20 one of 2,000 l/min, each with a crew of one plus eight, the HLF carrying an extended minimum load of rescue equipment; the TLF 3000 carries at least 3,000 l of water in mass class M, and the TLF 4000 at least 4,000 l of water and 500 l of foam in mass class M or S. The DIN type list of fire vehicles (26th revision, April 2026) places the types in finer mass bands. In its pump column, FPN 10-2000 is the EN 1028 designation of a normal-pressure pump rated at 2,000 l/min at 10 bar.

For the LF 20 and HLF 20 the list requires the maximum axle load of 10 t that DIN 14090 sets for fire-brigade areas on premises; for a TLF 4000 above 16 t it notes that the 10 t may be exceeded, which limits its use on such areas.

In Türkiye, the municipal fire regulation (Belediye İtfaiye Yönetmeliği) calls the fire vehicle a special-purpose vehicle (SC) under the road traffic rules, to be built within “TS, EN veya muadili uluslararası standartlar”, and sets minimum fleets by population — for 100,000 to 200,000 inhabitants, for example, six firefighting vehicles and two ladder vehicles among others. A 2017 technical specification of the state supplier DMO for fire tenders with portable ladders defines six classes from 7.5–8 t to 25–26 t with water tanks of 2,000 to 10,000 l, on 4x2 or 4x4 chassis up to class 5 and 6x2 or 6x4 for class 6. It requires the manufacturer to hold a certificate of conformity with TS EN 1846-1, 2 and 3, and the pump to be driven from a gearbox PTO that the chassis maker approves. Axle layouts such as 6x4 are explained in axle configurations.

Chassis the makers offer for fire service

In alphabetical order, as each maker presents it; for DAF and BMC we found no fire-service page:

• Ford Trucks. Ford’s Turkish page offers fire trucks and water tenders as 4x2, 6x2, 6x4 and 8x4, with water tanks of 2,000 to 18,000 l and ladders up to 30 m, though its model cards also list 32 m ladders; the cards run from the 18-tonne 1833 DC 4x2 to the 4145D 8x4, shown as an 18,000 l supply vehicle. Ford’s list of approved body builders includes Baksan, KARBA and Katmerciler, without saying who builds which body.
• Iveco. Iveco presents the Eurocargo 4x4, at 11 to 15 t, as a match for firefighting and civil protection trucks. Magirus, the fire-body maker, has belonged to Mutares rather than Iveco since 3 January 2025.
• MAN. MAN delivers fire engines, rescue vehicles and turntable ladders ex works, with crew cabs for up to seven people (1+6), switchable or permanent all-wheel drive or HydroDrive, and a clutch-independent mechanical PTO for pumps, winches, alternators and turntable ladders. Its electric eTGM 16.285, a 16-tonne 4x2, has 160 kWh usable, a range of up to 225 km and charging at up to 250 kW.
• Mercedes-Benz. Mercedes-Benz offers the Atego, up to 16.8 t, for bodies 3,300 mm high and with a fire-service gearbox programme; the Arocs from 18 to 48 t and from 4x2 to 8x8, with a 10-tonne front axle; the low-entry Econic at 18, 26 and 32 t, whose optional low cab leaves more room for ladder bodies; and the Unimog, which it says meets DIN 14530 and DIN 14555, with an engine PTO of 600 Nm and a crew cab for up to seven.
• Renault Trucks. Renault matches its D range to the EN 1846 categories — urban (1), rural (2) and forest (3) — with crew cabs for six or eight at 12 to 15 t and engine PTOs of 320 or 450 Nm, and offers the D Wide, C and K for heavier appliances, with approach angles of up to 37°.
• Scania. Scania names fire engines, water and foam carriers, turntable ladders and aerial platforms among its fire applications and recommends its CrewCab and P, L and R series. Its group page says the CrewCab carries up to eight passengers; its UK page gives seating for up to five passengers, and up to eight seats in the long cab.
• Volvo. Volvo offers the FL, FE, FM and FMX for fire service. Its FM and FMX crew cab for up to nine people was designed with body builders such as Rosenbauer, developed on the basis of EN 1846, impact-tested to ECE R29-03 and offered with a PTO of up to 2,000 Nm.

Crew cabs and other cab types are compared in truck cabs explained.

Bodies and body builders

Body builders publish pumps, tanks and ladder heights, and most of them build on several chassis makes:

• Rosenbauer (Austria) says its AT bodies “can be built on different chassis from various European chassis manufacturers”, with water tanks of 1,000 to 5,500 l and pumps of up to 4,500 l/min; its data sheets show an HLF 20 on a MAN TGM 4x4 and a TLFA 3000 on a Scania P420 4x4. Its aerial platforms reach 32 to 62 m.
• Magirus (Germany) gives its M32L turntable ladder a working height of 32 m and a rescue height of 30.5 m under DIN EN 14043, on 16-tonne class chassis such as the Iveco Eurocargo.
• Ziegler (Germany, CIMC group) shows an HLF 20 XL on a MAN TGM 13.320 4x4 at 16,000 kg with a 2,000 l tank and a 3,000 l/min pump. Schlingmann (Germany) builds its VARUS bodies for road and all-wheel-drive chassis, for crews of up to nine; EMPL (Austria) mounts its tanker bodies on a galvanised subframe; and Gimaex (France) offers its FPT pumper on Renault Trucks, MAN, Scania and Mercedes-Benz chassis.
• Turkish builders publish on their own sites ladder vehicles of 12 to 64 m and pumpers for chassis from 7,500 kg: Volkan (ladders up to 60 m, to TS EN 14043), KARBA (pumpers for chassis of at least 7,500, 15,000 and 18,000 kg, and Magirus distribution in Türkiye), Katmerciler and Baksan. None of them names a chassis make on the pages we read.

Electric fire engines

Volvo’s fire page gives the electric FL up to 180 kW and a range of up to 450 km, and the electric FE up to 225 kW and 275 km. Volvo’s 2025 overview of electric refuse trucks gives the FL Electric 130 kW of continuous power; the fire page does not say whether its 180 kW is a peak or a continuous figure. Gross and usable battery capacity are explained in installed vs usable battery capacity, and how makers arrive at range figures in how electric truck range is declared. How makers document electric trucks and buses for fire crews at an accident is covered in rescue sheets for electric trucks and buses.
