Sinotruk HOWO 4ton Dry Powder Fire Fighting Truck

The Sinotruk HOWO 4-ton Dry Powder Fire Fighting Truck is a specialized emergency vehicle designed for industrial, chemical, and general fire response, particularly effective against fires where water is unsuitable.

The term "4-ton" typically refers to the capacity of the dry chemical agent the truck carries.

This type of fire truck is usually a combined or specialized vehicle built on a reliable Sinotruk HOWO chassis.

1. Chassis and Cabin
   • Chassis Brand: Sinotruk HOWO (a well-known Chinese heavy-duty truck manufacturer).
   • Drive Type: Most commonly 4x2 (two-axle, rear-wheel drive) for this size, though other configurations exist.
   • Engine: Diesel engine, often in the range of 250-300 HP, providing strong power for rapid response.
   • Cabin: Typically features a double row/crew cabin design to accommodate a full firefighting team (e.g., 2 + 4 persons), often with fixtures for Self-Contained Breathing Apparatus (SCBA) in the rear seats.
2. Fire Fighting System

   The core function revolves around the dry chemical system:

   • Dry Powder Tank Capacity: The defining feature, usually designed to carry 4,000 kg (4 tons) of dry chemical powder (often ABC multi-purpose type).
   • Pressurization System: The powder is expelled by a separate high-pressure gas system, typically using Nitrogen (N₂ ) cylinders which provide the necessary pressure to push the powder through the piping and out of the monitor or hose reels.
   • Dry Powder Monitor/Gun (Cannon): A powerful nozzle mounted on the roof, capable of delivering a high flow rate of dry powder over long distances (e.g., ≥40 meters).
   • Hose Reels: Equipped with smaller hose reels and nozzles for closer-range, high-precision dry powder application.
   • Tank Material: The dry powder tank is a high-pressure vessel, often constructed from specialized high-strength steel (Q345R) to handle the working pressure (typically around 1.4 MPa).
3. Combined Capability (Common Variation)

   Many fire trucks labeled with a powder capacity are actually Combined Water/Foam/Dry Powder Trucks (also known as multi-functional fire trucks). In these cases, the 4-ton capacity might be for one or a combination of agents:

   • A combined truck may carry a smaller dry powder tank (e.g., 2,000 kg or 3,000 kg) alongside tanks for water and foam concentrate.
   • The primary function is to provide versatility for combating different classes of fires (Class A, B, C, and D).

Dry powder fire trucks are essential for specific fire classes:

• Class B Fires: Flammable liquids (petrol, oil, grease).
• Class C Fires: Flammable gases.
• Class E Fires (Electrical): Live electrical equipment, as the dry powder is non-conductive and non-damaging to electronics (unlike water).

They are highly valued in petrochemical industries, oil depots, chemical plants, airports, and other areas with high risks of liquid/gas fires.

Sinotruk HOWO 4 Ton Dry Powder Fire Fighting Truck is a specialized vehicle designed for combating fires, particularly those involving flammable liquids, combustible gases, and some electrical fires. Sinotruk, through its HOWO line, produces a range of fire fighting trucks, including those with dry powder systems.

Technical date :

The Sinotruk HOWO 4-ton (4000kg) Dry Powder Fire Fighting Truck is a specialized fire apparatus, often used in industries like petrochemicals, due to its effectiveness against certain types of fires (flammable liquids, gases, and live equipment).

Here are the general production and detail points based on typical models:

1. Chassis and Cab
   • Chassis: Typically based on a Sinotruk HOWO series chassis (e.g., HOWO TX5, or similar 4x2 drive models).
   • Engine: Diesel engine, with varying horsepower (e.g., around 250-350 HP) to ensure adequate power for the vehicle and fire-fighting system.
   • Cab: Usually a double-row cab designed to accommodate a larger fire crew (e.g., 2+4 or 5-6 total passengers). Often features a wide field of vision and a cab turnover feature for engine maintenance.
   • Transmission: Manual transmission (e.g., 10 forward and 2 reverse gears).
   • Overall Dimensions & Weight: Varies by manufacturer, but maximum GVW is often around 19,000 kg, and overall dimensions are roughly 8600×2500×3450 mm.
2. Dry Powder System (The Fire Fighting Core)

   The truck's primary function is based on a dry powder fire extinguishing system, often using ABC dry powder agent.

   Dry Powder Tank(s):
   • Capacity: 4000 kg, often divided into two independent tanks (e.g., 2×2000 kg).
   • Material: High-quality steel like Q345R or Q345B.
   • Working Principle: Utilizes the nitrogen push principle to eject the dry powder.
   Pressure:
   • Designed Pressure: Approximately 1.7 MPa.
   • Working Pressure: Approximately 1.4 MPa (Maximum).
   Nitrogen System:
   • Cylinders: Equipped with multiple high-pressure nitrogen cylinders (e.g., 12 to 24 cylinders with 70L capacity each) to provide the propellant for the powder.
   • Pressure: Maximum working pressure of nitrogen cylinders is around 15 MPa.
   Discharge Devices:
   • Dry Powder Monitor (Cannon): Mounted on the roof for long-range and large-scale fires.
   • Output: Typically around 30 kg/s to 40 kg/s.
   • Effective Range: ≥35 meters, sometimes up to 45 meters.
   • Rotation: ≥360 ∘ (Horizontal).
   Dry Powder Gun/Hose Reels:
   • Equipped with one or more hose reels (e.g., 30m length) for manual close-range firefighting.
   • Output: ≥2.5 kg/s.
   • Range: ≥12 meters.
   • Control: The powder intake and discharge are regulated by pneumatic and/or manual valves.
3. Body Structure and Compartments
   • Body Frame: Main frame often welded with high-quality square pipe.
   • Storage Compartments: Located on the sides of the body, enclosed with aluminum alloy shutters for easy access to firefighting equipment. The compartments are typically lit with LED lights.
   • Equipment: Includes various standard firefighting tools like fire axes, hose reels, fire extinguishers, suction hoses, etc.
   • Surface Treatment: The tank and body surfaces are often sprayed with multiple layers of anti-rust paint and decorative paint for durability and good appearance.

Sino howo 4X4 6tons 4WD 1000gallon to 1500 Gallons Water Tank Fire Truck Application:

• Primary Use: Extinguishing fires involving flammable liquids (Class B), flammable gases (Class C), and live electrical equipment (Class E).
• Specialized Role: Highly effective in combating large-scale chemical plant pipeline fires and is commonly used by petrochemical and industrial enterprises. The dry powder acts by chemical inhibition (interrupting the combustion chain reaction) and physical isolation (forming a layer on combustibles).
