The Class 155 Crash Truck was built on the Kenworth and Brockway 6 ton, 6x6 chassis.  
The bodies were manufactured by Mack and American LaFrance.  The vehicles constructed
by Mack were equipped with a Hale 325 gpm., 600 psi. pump which was powered by a
Continental engine.  The American LaFrance trucks were supplied with their own 4 stage,

mounted at the rear of the vehicle.  The pump supplied water and foam to 2 turret guns
mounted atop the rig and the water tank held 1000 gals.  Two, 100 ft, 3/4 in. handlines were
carried in open bins on either side of the rig and a third was stored in a open body
compartment.  High pressure fog nozzles were attached to each line.  Portable fire
extinguishers, ladders and numberous hand tools for rescue work were also carried.   A early
version of the Class 155 was mounted on the Mack, NM, 6 ton, 6x6 chassis.

The Class 150 Crash Truck was built on the Reo and Sterling, 6x6, 7 ton chassis.  the body and fire fighting
equipment was manufactured by the Cardox Corp.  Equipped with 6,000 pounds of CO2 and 300 gallons of foam

CO2 hand lines on the truck, two located on large hose reels each holding 100 feet of 1 in high pressure hose and
two 100 foot 5/8 in lines coiled in a hose bed located over the rear wheels.  These two lines were attached to 5 foot
