I google mining water truck, only get information from towhaul. Is there other manufacturer produce about 180 m3 water tank?
Closest to you would probably be Ground Force, they're in Idaho.
180m3 means what? 180 cubic meters? Surely not.
50,000 gallons, roughly 200 ton? No worries, easily done. Mind you filling it might present a challenge in some areas.... "Ground Force’s designs and manufactures the World’s Largest water tanks, with capacities in excess of 60,000 gallons. "
I missed the minning application... That's one hell of a mobile tank!
GF produce water tanks up to the size of a 793, so that would be a 240-tonne, or 240 cu.m. of water, payload capacity http://gfworldwide.com/product/water-trucks/ MEGA Corp out of Albuquerque NM also produce tanks up to 793 size for mining haul road dust suppression. http://www.megacorpinc.com/
