M2117 6×6 Airport Fire Truck with Rear HALE 6000 L/min
The M2117 is a 6×6 airport fire truck with an imported chassis. A rear-mounted HALE RSD100 pump delivers 6000 L/min at 1.0 MPa, and a roof monitor flows 4800 L/min. It seats six and carries 9500 L of water and 1200 L of foam. The first pass can be made from the tank while a supply is arranged, which suits a runway alert.
A DCEC CUMMINS L375 supercharger-air cooled diesel engine rated 276 kW at 2200 rpm drives the vehicle, with 1480 N.m of torque at 1400 rpm and an 800 rpm idle. Working temperature spans -20 to +40 degrees at a common workload of 80 percent, which keeps the pump drive within its rating through a long standby.
Piping uses stainless steel 304 throughout. Tank suction runs through DN150 butterfly valves with electric and manual operation, and an outer DN150 suction port carries its own butterfly valve. Each side provides two DN80 normal pressure outlets with manual valves, while a DN100 pipe feeds the roof cannon through a pneumatic switch. Two tank inlets on each side, four in total, allow refilling from either flank.
The Actros long cab offers 1400 mm of standing height, two doors and electric windows. The 1+1+4 layout includes sleeping seats, which keeps a relief crew rested through a long standby at the threshold. Service access is from the cab side, and the pump room sits behind the rear axle. The pump runs from its own rear-mounted engine, so the main engine can be shut down while drafting.

Where it fits
Airport crash tenders that need a high-volume rear pump and a roof monitor for foam blanket work. The same appliance must carry a full crew and rotate them through a long standby at a busy aerodrome.
