diesel-powered vehicle, with a hydrostatic drive system
that transmits power to the rear wheels. Steering is
preformed by a single hydraulic cylinder and tie rod
assembly that controls the front wheels. Dynamic
vehicle braking is provided by the hydrostatic drive
system. When the accelerator is released, the brakes
automatically engage.
Separate tanks within the
vehicle chassis carry 750 gallons of water and 55
gallons of AFFF (Aqueous Film-Forming Foam).
Three 20-pound fire extinguishers containing HALON
1211 (Halogenated Extinguishing Agent) are stored on
the right side of the vehicle. One nursing line
connection on each side of the vehicle provides AFFF
mixture from the ship's system directly to the vehicle's
water pump.
The vehicle has seating for a crew of two. The
driver compartment is located at the left forward end of
the vehicle and contains the main control panel for
activating the fire-fighting systems. AFFF can be
sprayed from both the forward turret nozzle and
handline hose reel nozzle.
These nozzles operate
independently and can be used simultaneously to make
this vehicle ready for fire-fighting duty.
