Main configuration and function introduction of water tank fire truck

top body

The top-loading box is composed of two parts: the fireman's cabin and the box. The shape of the box is based on the outline of the cab. The outline of the equipment box, the tank and the pump room pass through the front side deflector of the box. The room maintains overall harmony and transitions naturally.

The upper ends of both sides of the carriage are made of aluminum alloy hoardings and embedded with lighting and warning lamps, which meet the standards of fire warning lamps and signs, and are beautiful and novel in appearance and highly recognizable. The pump room, equipment compartment and other working areas are designed with hidden LED light strips for night operation lighting.

The lower skirt of the box body adopts the structure of the eversion pedal door, which is made of light aluminum alloy profiles, and the end face is developed with a special decorative sealing plate. The end face of the flip pedal door is equipped with an inlaid warning light. When the pedal door is open, it exceeds the size limit of the vehicle, and the warning light will continue to flash to indicate; after the pedal door is closed, the contact switch will automatically turn off the power and the warning light will turn off. The wheel part of the lower skirt of the car body is also designed with wheel covers in combination with the shape of the car body, fully considering the maintainability, and covering and beautifying the lower skirt of the car body.

The rear of the box is designed with a folding aluminum alloy climbing ladder. The folding parts of the ladder are locked by stainless steel buckles. The hinges of the upper and lower sections of the ladder are equipped with shock-absorbing rubber pads. The upper part of the ladder is equipped with double handrail protection. , the step depth and height meet the requirements of ergonomics and related standards. The top of the box is equipped with a pull-ladder flip frame, equipped with a 6M aluminum alloy pull-ladder, and the top pull-ladder can be put down conveniently and quickly through a stainless steel pull rod. The roof is also equipped with a suction pipe, which can be quickly connected to the required length through the cassette quick connectors at both ends of the water pipe, which is convenient and fast to operate. The top of the carriage is all paved with anti-slip patterned aluminum plates, which can safely walk and operate the equipment.

Separate crew compartment

The front of the box is provided with an independent crew compartment, which can accommodate 7 firefighters in combat state. The two sides are equipped with tempered glass doors and automatic retractable flip pedals, and both sides of the doors are equipped with glass sliding windows. The passenger compartment is equipped with an independent heating and cooling air-conditioning system, and the walls and roof are covered with flame-retardant interior materials, which are fixed with decorative aluminum profile battens.

There are 7 sets of single seats in the independent passenger compartment, 4 sets of universal adjustable air breathing apparatus brackets are embedded in the seat back, and air breathing apparatus is embedded. The air respirator has a mechanical locking mechanism to lock it. The release handle of the mechanical locking mechanism is at the place where the occupant is convenient to touch. The size of the handle ensures that it can be operated with protective gloves. Firefighters can quickly carry air respirators on their way to the fire and rescue operations, and immediately start firefighting and rescue operations when they arrive at the fire scene.

The passenger compartment is equipped with door ladders and handrails that are convenient for firefighters to get up and down. The handrails are reliably fixed to the car body and can withstand 100kg of pulling force without falling off and breaking. The armrest is made of metal material, and the outside of the armrest is coated with a non-metallic layer and has anti-skid patterns, which are high enough for passengers to grasp on the seat. According to the opening/closing state of the door, the pedal is controlled by intelligent induction linkage to retract and lower. The boarding and exiting pedals of the passenger compartment are equipped with lighting devices, and the lighting switch is controlled by the door linkage, and the lighting is linked on/off when the door is opened/closed. The floor mats laid on the floor of the passenger compartment are made of flame-retardant materials, whose flame-retardant properties meet the requirements of GB8410, meet the requirements of environmental protection, and can reduce noise, prevent slippage, and facilitate cleaning. The overall interior of the passenger compartment is equipped with an LED lighting system, and the top is equipped with dual-system air conditioning.
Passenger compartment overhead air conditioner cooling rated power: 940W; heating rated power: 900W; drive type: 24V DC power drive; small and compact does not occupy the interior space of the car; the integrated design of the overall copper pipe and pipeline of the air conditioner, the pipeline connection is reliable and reduces the refrigerant The probability of leakage is increased, and the service life of the product is increased.
