An all-terrain fire fighting apparatus has a high power-to-weight ratio, a hydraulic skid steer drive system, a drive-by-wire control system, a proportionally joystick controlled nozzle turret, and a 1500 psi foam injecting water supply system which supplies the nozzle turret and a high-pressure hos
An all-terrain fire fighting apparatus has a high power-to-weight ratio, a hydraulic skid steer drive system, a drive-by-wire control system, a proportionally joystick controlled nozzle turret, and a 1500 psi foam injecting water supply system which supplies the nozzle turret and a high-pressure hose mounted on a reel. To dissipate heat load from the fire fighting apparatus systems, the fire fighting apparatus cooling system employs a cooling shroud in the form of a box with multiple system radiators stacked on one face of the box and the remaining faces containing exhaust fans mounted to draw air out of the box and through the stacked heat exchangers. The fire fighting apparatus is capable of being operated remotely by means of onboard GPS, real-time imaging, and inputs to the joystick controller and fire fighting apparatus drive-by-wire system.
