Sinotruk Howo 7 tons dry powder water combined fire truck

Basic introduction of Sinotruk Howo 7 tons dry powder water combined fire truck

Sinotruk Howo 7 tons of dry powder water combined fire truck is refitted from the special chassis ZZ5207TXFV471GE5 of Sinotruk Howo fire truck. The whole vehicle is composed of two parts: the fireman's cabin and the body. The cabin is an original double row, which can take 2+4 people. The vehicle is an exposed tank structure, and the front of the body is an equipment box (dry powder tank, nitrogen bottle, dry powder system). ), the middle is the water tank, and the rear is the pump room. The liquid carrier tank is made of high-quality carbon steel, and the interior is sprayed with epoxy primer and epoxy asphalt paint. It is elastically connected to the chassis. The water carrying capacity is 4700kg (SG80). The pump has a rated flow of 60L/S, and the roof is equipped with PS60W vehicle fire monitor and PF30 dry powder monitor produced by Chengdu West Fire Machinery Co., Ltd. The biggest feature of the car is the large liquid carrying capacity, good handling and easy maintenance. It can be widely used in public security fire brigade, factories and mines, communities, docks and other places to fight large oil fires and general material fires.

The fire performance of the whole vehicle meets the requirements of the GB7956-2014 standard; the chassis has passed the national compulsory product certification; the engine emission meets the requirements of the fifth stage limit of GB17691-2005 (National V standard); the whole vehicle has passed the inspection of the National Fire Equipment Quality Supervision and Inspection Center (Report No.: Zb201631223/24) and has been included in the Ministry of Industry and Information Technology's announcement of new automotive products, and CCCF is in the process of applying.
