Our die-cast model of this machine will be based on the finely rendered details of our Cat 777G haul truck. In keeping with the design of the actual machine, our replica of the Mega MTT20 water tank will pin to the truck chassis. Other details that will be replicated on the model include the Mega water pump feeding the rear spray bar with 4 horizontal spray heads, the 2 vertical spray head valves mounted on top of the tank and the water cannon fed by an additional hose from the foam agent system reservoir embedded in the tank. A fill port safety grate, ladder and safety rails are among the other realistic details found on the model.
Paint and markings are approved by the manufacturer for accuracy.
Includes a signed and serial-numbered spec brochure reproduction.

When mining and construction sites have a need for a lot of water, a MEGA MTT20 with 20,000 gallons on board is more often than not the carrier of choice. The tank pins to the rear pivot mounts of a Cat 777G off-highway truck chassis and is equipped with vertical baffles and an internal shell to help ensure water movement is not an issue while underway. The integration of the two major components is so seamless the original warranty on the truck is honored by Caterpillar.
The heart of the Mega spray system is their water pump which is powered by the hydraulic hoist pump and valve system on the truck. The MTT features the Mega M4B water pump which is capable of delivering over 1000 gpm at more than 100 psi. Mega developed and patented their spray heads in 1976 and since then they have been subject to continuous improvements. These spray heads are fully adjustable for volume, width, and direction in two axis from the spray bar. A spray pattern measuring 90 feet wide is within the capability of these systems.
