250cc Heavy Load Tricycle

A plain water hauler only delivers water; this truck carries a complete working water circuit. A power take-off (or an optional standalone small petrol engine) drives a self-priming centrifugal pump, typically 18–30 m³/h, with around 30 m head and 6–8 m suction lift, so it can draw straight from ponds, rivers or hydrants. A strainer protects the pump inlet - the orange-and-black box mounted beside the tank in the second photo - trapping sand and debris before they reach the impeller or the lines. Four controlled circuits, each with its own ball valve, cover the actual work. Front-facing jet nozzles wash mud off road surfaces. A duckbill rear sprinkler plus side rose heads lay down a 12–14 m wide water curtain for dust control and irrigation. A 360-degree water cannon on top or at the rear throws a solid jet roughly 25–30 m and switches to fog spray, serving fire attack, cooling and dust suppression alike. A standard DN65 fire connection accepts regular fire hoses for fast hydrant refill or series operation with an external pump. Drain valves at every low point let the operator empty the pump and lines after work in freezing weather, preventing cracked casings and burst pipes.
