When it comes to the scania chassis fire truck, most friends will think of one word, that is, hard. That's right, Scania's R650 8X4 heavy-duty chassis is one of the best heavy-duty chassis in the fire truck industry, and it's mostly used on heavy-duty foam fire trucks. The fire truck that uses the R650 chassis introduced in this article is the strongest in the heavy foam fire truck.
Scania R650
R650 this fire truck is not unfamiliar to everyone, is the last generation of R620, Scania launched the latest chassis in China, but also the current domestic maximum horsepower fire truck chassis. It uses Scania's V8 engine with a displacement of 16 liters and a maximum power of 650 horsepower.
Some people asked, fire trucks equipped with such a large engine, in addition to running fast, there is no use, is a waste. In fact, the long-term work of the fire pump requires the engine to drive the power take-off drive, and in the event of industrial fires, it needs to be extinguished for a long time, and the engine that can work for a long time and reliably is particularly critical. So the fire truck buys the chassis, and more importantly the reliable operation of the engine.
For compatibility with the bodywork, the car features a single-row day cab. The cab configuration is more practical, with only two areas of the four-pair multi-function instrument cluster equipped with buttons and wheels, and the symmetrical instrument panel at the rear is also standard. The car is not equipped with a hydraulic retarder, only engine auxiliary braking, but uses Scania's intelligent shift system.
The area on the center console where the LCD screen was originally installed was converted into a radio and a topsite prompt, a hand-mounted interface. The topsize plant moves the display above the center console, with functions such as navigation, vehicle surround view, face recognition, vehicle monitoring and so on.
Back to the chassis configuration, the rear axle uses Scania's single-stage deceleration bridge; the front axle is a flat steel rim, the rear axle is also a steel rim, and the whole car uses Bridgestone tires. In addition, the fire truck of the Scania chassis has a stabilizer bar throughout the vehicle to ensure the stability of the vehicle at high speed.
Sichuan industrial foam fire truck
What is an industrial foam fire truck? Unlike the conventional fire trucks we see, industrial foam fire trucks must have "cannons" that use large water flows to control industrial fires. In addition, a super-large flow pump and a large volume tank are required to ensure that the vehicle has sustained combat effectiveness.
The car's tops are manufactured by Sichuan's Sichuan, and the style of the body is somewhat similar to that of the Austrian Rosenbauer fire truck, using coal-black equipment roller shutter doors. The exterior styling is very simple, without too many exaggerated lines.
Located in the middle of the body is the car's independent occupant compartment, which features black doors and large window panes. The lower boarding staircase is folded and hidden, with a narrow lower width and upper narrowness, making it easy for firefighters to get on and off the train.
Four firefighter seats were installed in the crew compartment, all of which were folded and had space on the back for air breathing bottles. In addition, there are several storage boxes under the seat, and some fire extinguishing tools can be put in the car and can be worn on the car.
The interior of the crew compartment uses blue lighting, and there are blue atmosphere lights on the roof, and those who are not paying attention will really think that they have entered a motorhome. In addition, independent air conditioning has been added to the interior of the cabin, which is also the standard of the independent occupant compartment of the current fire truck.
The crew compartment features a monitoring panel in the cab, interior lighting in the crew compartment, and control buttons for the left and right ladders. In addition, the panel also integrates an intercom system, through which the system and cab voice calls can be made.
Inside the equipment box near the crew compartment, the water belt, the water separator and other equipment are neatly arranged together, and the vehicle function is very pure, all of which are equipment for supplying the vehicle with water. The car carries 10 tons of foam and 10 tons of water, with a total liquid load of up to 20 tons. But in the face of such a large flow, the 20 tons of water and foam are only enough to last for a few minutes.
Top control panel located on the rear side of the car
There is a row of water inlets at the rear of the car, and the water inlets at the left and right ends are fire cannons that independently supply the roof, while the three water inlets in the middle supply fire pumps. In the midst of firefighting, the vehicle requires additional water supply vehicles to be able to fight for long periods of time.
Opening the door of the equipment compartment at the rear of the car, a huge inlet pipe appeared in front of us. The vehicle is equipped with a fire pump with a flow rate of up to 15,000 liters per minute, and the high-flow fire pump is specially used in industrial fires.
In addition to the super flow of fire pumps, the roof is also installed with 3 fire guns, the middle of the tube is the main gun, the flow rate can reach 12,000 liters per minute, in the industrial fire play a role in extinguishing the fire. A small cannon is installed on the left and right sides, the two guns are called isolation guns, which is simply to cool the adjacent tanks and prevent the high temperature from igniting other tanks or flammable facilities. The flow rate of the two isolation guns also reached 6,000 liters per minute.
summary
Such a strong Scania R650 V8 chassis, with a large load of liquid, a large flow of fire tops appear very solid, giving people a full sense of security. Of course, we all hope that fire trucks will only appear in the drill, they can be useless, but not without.
