Isuzu heavy fire rescue truck

Isuzu heavy-duty fire rescue truck are mainly used for fire fighting and rescue. They are vehicles used by firefighting forces for fire extinguishing, auxiliary fire extinguishing or fire rescue. The Isuzu heavy-duty fire rescue vehicle in this article is a dry powder and water vehicle. The Isuzu heavy-duty fire rescue truck is mainly equipped with a vehicle fire pump, a water tank and a dry powder fire extinguishing agent tank. It can spray dry powder and water to extinguish fires at the same time or in sequence. When the fire scene requires dry powder and water to be used to extinguish the fire at the same time, firefighters can operate the fire truck to spray the dry powder and water onto the fire source in sequence or at the same time to achieve the effect of quickly extinguishing the fire source.

At the same time, the fire truck can also accurately calculate the amount of dry powder required to extinguish the fire based on the actual conditions of the fire scene, so that the fire truck can be as close to the fire source as possible, aiming at the fire point, and striving to successfully extinguish the fire in one go. When dry powder is used to rescue petrochemical fires, the fire scene commander should mobilize corresponding forces as needed and do a good job of cover. At the same time, he should consider using water tanks for subsequent attacks to prevent re-ignition and provide a strong guarantee for successful fire fighting.

Modified with 8x4 Isuzu Giga VC61 VC66 heavy-duty chassis. The fire truck is mainly composed of three parts: a double-row cab, a pump room, and a dry powder system. There are 4 seats in the back row and are equipped with air respirator holders. The vehicle is designed with an exposed tank split structure (detachable) for easy transportation and use.

The vehicle adopts an exposed tank structure. The front of the vehicle is the equipment box (dry powder tank, nitrogen bottle, dry powder system and English control panel), the middle is a 15,000-liter water tank and 3,000-liter dry powder, and the back is the pump room. The pump room is equipped with a fire pump, which is used to pump water or foam fire extinguishing agent from the tank and deliver it to the fire extinguishing site.

The Isuzu heavy-duty fire rescue truck cab is an all-metal enclosed structure with double rows of seats, four doors, and a panoramic curved windshield. In addition, new front visors, front bumpers, front combination lamps, door windows and cowl visors are optionally available to improve the safety and comfort of the cab.

Fire trucks are equipped with fire water cannons, dry powder cannons, dry powder reels and guns. The model of the fire water cannon is PL48, with a flow rate of 60L/S, and a range of up to 70M. The model of the dry powder cannon is PF30, with a 360° rotation angle and a -15~+80° pitch angle, and a range of up to 35M. The dry powder reel and gun have an injection rate greater than 2.5kg/s and a range greater than 12M. In addition, the vehicle is equipped with 6 nitrogen cylinders to provide the pressure required for fire extinguishing agents.

The electrical configuration of fire trucks includes long rows of warning lights, fire scene lights, strobe lights and safety sign lights. There is a long row of warning lights on the top front of the cab, and a 24V60W fire scene lighting behind the body. There are red and blue strobe lights on both sides of the vehicle, and safety sign lights are installed below. The crew compartment, equipment box, and pump room are all equipped with lights. In addition, the vehicle is also equipped with a 100W alarm light and turn light switch, and a pre-climb interface for communication equipment to facilitate communication with other firefighting vehicles or command centers.

Main parameters

The working principle of Isuzu water-dry powder fire truck is as follows:

Dry powder fire extinguishing system: Fire trucks are equipped with a dry powder fire extinguishing system, which usually uses a pressure tank device to quickly release dry powder to the fire source. The operator sends the dry powder into the nozzle by controlling the valve to form a dry powder jet to cover the fire area and extinguish the fire.

Water fire extinguishing system: Fire trucks are also equipped with a water fire extinguishing system, usually a water pump system and a water gun. The operator controls the water pump to draw water from the water tank or external water source, and transports it through the pipeline to the water gun to achieve fire extinguishing spray.

Linkage system: In practical applications, operators can choose to use dry powder or water according to the fire situation, or they can use two fire extinguishing systems in conjunction at the same time. Through the console, the operator can control the start and stop of the dry powder system and water system, and adjust the injection direction, pressure and amount as needed.

Fire extinguishing strategy: Depending on the type of fire and fire scene conditions, operators can flexibly use water and dry powder systems for fire extinguishing operations. Dry powder is mainly used to extinguish solid and liquid fires, while water is suitable for cooling burning materials and extinguishing flammable liquid fires.

Safety measures: Operators must follow fire training and guidance to ensure safety during operation. Fire trucks are usually equipped with safety devices such as emergency stop buttons to ensure the safety of fire-fighting operations.
