Детали для пожарных машин

A fire fighting water truck and an ordinary water truck may look similar. Both are large vehicles with water tanks, pumps, and hoses. However, their design, components, and intended purposes are fundamentally different.

This article explains the key differences between fire fighting water trucks (also known as multi-purpose water trucks or forest fire trucks) and ordinary water trucks from multiple perspectives: appearance, configuration, working principle, application, and more.

» I. What Is a Fire Fighting Water Truck?

A fire fighting water truck is also known as a multi-purpose water truck, forest fire truck, or fire water supply truck. It belongs to the civil fire truck series. This vehicle combines firefighting and watering functions into one unit. It sits between a professional fire truck and an ordinary water truck.

Primary applications:

Landscaping and green belt irrigation
Firefighting and fire suppression
Emergency fire water supply
Dust suppression in mines and construction sites
Small-scale firefighting in residential communities
Pesticide spraying (optional)

Key characteristics:

Tank capacity: 2,000 – 12,000 liters
Pump type: Fire pump driven by sandwich PTO
Spray range: 50 meters or more
Pump flow rate: Up to 100 cubic meters per hour
Color: Fire red or engineering yellow
Roof monitor: 360° horizontal rotation, -30° to 80° vertical tilt

» II. What Is an Ordinary Water Truck?

An ordinary water truck is a type of municipal vehicle built on a two-axle commercial chassis. It consists of an anti-corrosion water tank, a power take-off (PTO), a drive shaft, a dedicated self-priming water pump, a piping network, spray outlets, and a working platform.

Primary applications:

Landscaping and green belt irrigation
Road maintenance and cleaning
Dust suppression on construction sites
Street washing
Agricultural pesticide spraying (optional)
Emergency firefighting (limited capability)

Key characteristics:

Tank capacity: 5,000 – 20,000 liters
Pump type: Self-priming water pump (side-mounted PTO)
Spray range: 28 meters or less
Pump flow rate: Approximately 40 cubic meters per hour
Color: Usually matches the chassis cab color (white is common)

3. PTO and Power Transmission

Ordinary water truck:

Uses a side-mounted gear-type PTO
Power is taken from the transmission gear
Power transmission is relatively small
Cannot drive a high-pressure fire pump
Spray range is 28 meters or less

Fire fighting water truck:

Uses a sandwich-type full-power PTO
Engine directly drives the fire pump
Power transmission is much larger
Assembly is more complex
Spray range is 50 meters or more

4. Pump System

Parameter	Fire Fighting Water Truck	Ordinary Water Truck
Pump type	Fire pump	Self-priming water pump
PTO type	Sandwich type	Side-mounted type
Flow rate	Up to 100 m³/h (1,667 L/min)	Approximately 40 m³/h (667 L/min)
Pressure	1.0 – 1.5 MPa	0.3 – 0.5 MPa
Priming	Vacuum primer (30 seconds or less)	Self-priming (slower)
Suction capability	Can draft from open water	Limited or none

5. Fire Monitor (Water Cannon)

Feature	Fire Fighting Water Truck	Ordinary Water Truck
Type	Professional fire monitor	Basic spray gun
Location	Roof of tank	Rear working platform
Rotation	360° horizontal, -30° to 80° vertical	Limited or manual
Range	50 meters or more	28 meters or less
Flow rate	Up to 60 L/s	Lower
Control	Manual or remote	Manual only

6. Functionality

Ordinary water truck functions:

Front impact spray
Rear sprinkler
Side spray
High-altitude spray (basic)
Water gun
Pesticide spraying (optional)

Fire fighting water truck functions:

All ordinary water truck functions
High-pressure firefighting
Long-range fire monitor (50 meters or more)
Emergency fire water supply
Dust suppression (high flow)
Forest firefighting (access to rough terrain)
Can connect to fire hydrants
Can draft from lakes and rivers

Limitation: Fire fighting water trucks can only extinguish ordinary material fires (Class A fires). Professional fire trucks can handle Class B fires (flammable liquids) using foam or dry powder.

7. Purpose and Application

Factor	Fire Fighting Water Truck	Ordinary Water Truck
Primary use	Firefighting and watering	Watering only
Secondary use	Emergency water supply, dust control	Pesticide spraying
Suitable for	Towns without fire stations, factories, mines, forests, communities	Municipal sanitation, landscaping, construction
Firefighting capability	Small-scale fire suppression (Class A)	Very limited
Professional firefighting	No	No

8. Price

Factor	Fire Fighting Water Truck	Ordinary Water Truck
Purchase cost	Higher	Lower
Maintenance cost	Higher	Lower
Cost-effectiveness	One vehicle serves multiple purposes	Single purpose

» IV. Fire Fighting Water Truck vs. Professional Fire Truck

Some buyers confuse fire fighting water trucks with professional fire trucks. They are different.

Feature	Fire Fighting Water Truck	Professional Fire Truck

Landscaping and green belt irrigation	Ordinary water truck
Small-scale firefighting and daily watering	Fire fighting water truck
Firefighting for a town without a fire station	Fire fighting water truck
Emergency fire water supply	Fire fighting water truck
Forest firefighting access	Fire fighting water truck (forest type)
Professional firefighting (oil, chemical fires)	Professional fire truck
Complete rescue equipment	Professional fire truck

VI. Conclusion

Fire fighting water trucks and ordinary water trucks serve different purposes even though they look similar.

Ordinary water trucks are designed for daily municipal tasks: street cleaning, dust suppression, landscaping irrigation, and road maintenance. They have simple pumps, basic spray systems, and lower cost.

Fire fighting water trucks are multi-purpose vehicles that combine watering and firefighting functions. They feature sandwich PTOs, high-flow fire pumps, roof-mounted monitors, longer spray range (50 meters or more), and emergency lights. They are ideal for towns without professional fire stations, factories, mines, forest areas, and residential communities that need basic fire protection.

Fire fighting water trucks can only handle Class A fires (ordinary combustibles like wood, paper, and cloth). For flammable liquid fires (oil, gasoline, chemicals), a professional fire truck with foam or dry powder capability is required.

When choosing between these vehicles, consider actual needs, budget, and application scenarios. If only daily watering is needed, an ordinary water truck is sufficient. If firefighting capability is needed in addition to watering, a fire fighting water truck is the better choice.
