CPM3 Monitor Trailer

CPM3 Monitor Trailer supplied by SA Fire Protection

MONITOR TRAILER – CPM3

Model CPM3 is a high flow rate 22500–37500 lpm (5850-10000 gpm) monitor trailer which is used to gain mobility for high flow firefighting monitors. These trailers are used by industrial fire brigades to fight full surface fire on fuel tanks. The monitor trailer is made of a carbon steel structure on which an aluminum platform is located.

The trailer has four main wheels on the rear plus an additional rotating wheel on the front where the drawn bar with towing ring is connected. On the structure there are several connection equipped with couplings for the interconnection of fire hoses that deliver water to the trailer. On the main trailer flange a monitor is installed which can be equipped with either a nozzle or branch pipe.

The monitor trailer is provided with a connection for the foam concentrate supply, provided by a jet pump manifold supplied with the monitor trailer.
