QDT5300GXFPM140S fire-extinguishing water tanker with three rows of seat and large flow of foam is a new generation of heavy main firefighting truck of our company refitted from the chassis of HOWO ZZ5347V4647D1 special motor vehicle produced by China National Heavy Duty Truck Group Co., Ltd. The water pump system is equipped with middle-lower pressure fire pump for CB20.10/40.80-TB mass flow car and new PLKD64 remote control fire-fighting foam/water monitor produced by Shaanxi Aerospace Power Hi-tech Co., Ltd. The cab is remanufactured to integral three rows of seats and can hold 6~8 people; the integrated streamlined design creates attractive appearance, comfortable driving, large driving space, wide vision and convenient occupant activities, etc.
In addition to having the same fire performance with the common fire-fighting truck, this water tanker also has the water supply function under medium voltage over long distance, which enables the turret gun to extinguish larger scale oil and general material fire under static or moving state, and also can utilize the excellent medium pressure performance to complete the water supply support in long distance. In addition, the novel appearance, scientific pump system design, reasonable and complete fire equipment configuration make it more suitable to the actual fire control. Thus, this tanker is the ideal main fire fighting vehicle for police firefighting army, petrochemical enterprise, wharf, airport, expressway, large-scale enterprise and all kinds of full-time fire brigades.
