Abstract:
1. An extensible aerial boom for a liquid discharging vehicle comprising: a lower boom having an outer end and an inner end, the inner end being pivotally connected to the vehicle for movement in a vertical plane; an upper boom having an extensible portion and a stationary portion; an inner end on the stationary portion of the upper boom being pivotally connected to the outer end of the lower boom for enabling movement of the upper boom in the vertical plane; an outer end on the stationary portion of the upper boom; an outer end on the extensible portion of the upper boom that is moveable longitudinally with respect to the outer end of the stationary portion of the upper boom; a first fluid discharge nozzle, independently controlled in position and in fluid flow, associated with the outer end of the stationary portion of the upper boom discharging a first fluid for fighting a first fire; a second fluid discharge nozzle in a different plane from a plane of the first nozzle, independently controlled in position and fluid flow, associated with the outer end of the extensible boom discharging a second fluid for fighting a second fire; thereby enabling simultaneous discharge of fluid to two separate locations in a given area and wherein the fluid flow of the nozzles may be different and wherein the positions may be such that the nozzles each discharge fluid in the same direction; and wherein the spacing between the first individually controllable fluid discharge nozzle and the second individually controllable fluid discharge nozzle is varied by varying the amount of extension of the extensible portion of the upper boom.
