ISUZU 15 CBM Toilet Vacuum Truck
The ISUZU 15 CBM Toilet Vacuum Truck is a heavy-duty sanitation vehicle designed for efficient collection, transportation, and discharge of sewage, septic waste, sludge, and other liquid waste from septic tanks, public toilets, municipal drainage facilities, and industrial sanitation sites. Built on a robust ISUZU chassis with a large 15 CBM vacuum tank, the truck combines strong road performance with a powerful vacuum system, making it suitable for demanding municipal and environmental sanitation operations.
With overall dimensions of 11,995×2,530×3,930mm and a wheelbase of 3,985+1,370mm, the truck provides a stable platform for its large-capacity vacuum tank and associated suction equipment. The vehicle has a maximum speed of approximately 90km/h, while the specified front and rear axle loads of 2,580kg and 4,720kg provide a balanced chassis configuration for transporting liquid waste.
The truck is powered by an ISUZU 6UZ1-TCG51 diesel engine producing approximately 350HP, providing strong power for transporting a heavily loaded tank and operating on municipal and intercity roads. The 12-speed forward and 2-speed reverse transmission gives the driver a wide range of gear ratios for different road and load conditions, while the 315/80R22.5 steel-wire tires provide suitable support for heavy-duty operation.
The upper structure features a 15 CBM carbon steel vacuum tank manufactured from Q235B steel with a tank wall thickness of more than 5mm, providing a strong and durable container for handling sewage and liquid sludge. The vacuum system offers a suction range of approximately 28 meters, allowing the truck to reach septic tanks and waste collection points that are located some distance from the vehicle.
The vacuum system is designed to achieve a vacuum duration of ≤10 minutes, while the specified discharge time is approximately ≤4 minutes, allowing the truck to complete sewage collection and unloading operations efficiently. This makes the ISUZU 15 CBM Toilet Vacuum Truck a practical choice for municipal sanitation departments, sewage treatment contractors, property management companies, and industrial waste service providers.
Features
1. Heavy-Duty ISUZU Chassis
The ISUZU chassis provides a stable and durable foundation for the 15 CBM vacuum tank and sanitation equipment, with overall dimensions of 11,995×2,530×3,930mm and a 3,985+1,370mm wheelbase. The long wheelbase configuration helps distribute the weight of the large-capacity tank and liquid load more effectively, providing improved stability during transportation.
The truck is fitted with 315/80R22.5 steel-wire tires, which are designed to provide strong load-bearing capability and durability for heavy-duty road operation. The front and rear axle loads are specified at 2,580kg and 4,720kg respectively.
2. Powerful 350HP ISUZU Engine
The vehicle is powered by an ISUZU 6UZ1-TCG51 diesel engine with approximately 350HP, providing strong propulsion for transporting large quantities of sewage and sludge over both urban and longer-distance routes.
The powerful engine is particularly important for a 15 CBM vacuum truck because the vehicle’s total operating weight can increase significantly when the tank is filled. The 12-speed forward and 2-speed reverse transmission provides a broad range of gearing, allowing the driver to manage different road conditions and load levels more effectively.
3. Large 15 CBM Vacuum Tank
The 15 CBM vacuum tank provides substantial capacity for collecting and transporting sewage, septic waste, sludge, and other liquid contaminants, reducing the number of trips required between collection locations and disposal facilities.
The tank is manufactured from Q235B carbon steel, with a wall thickness exceeding 5mm, providing a strong structure suitable for repeated filling, vacuum suction, transportation, and discharge operations. The tank is designed specifically for handling liquid dirt and other sewage-related materials.
4. 28-Meter Suction Range
One of the major advantages of this ISUZU Toilet Vacuum Truck is its approximately 28-meter suction range, allowing operators to collect sewage from septic tanks, toilets, pits, and other locations without positioning the truck directly beside the waste source.
This extended working range provides greater flexibility when operating in residential areas, narrow streets, construction sites, industrial facilities, and other locations where vehicle access may be restricted.
5. Fast Vacuum Operation
The vacuum system is designed to achieve a specified vacuum duration of no more than 10 minutes, allowing the truck to create the necessary negative pressure for efficient sewage suction. The system is suitable for repeated collection operations throughout a working day.
Once the vehicle reaches the designated disposal location, the specified discharge duration is approximately 4 minutes or less, helping reduce turnaround time and allowing sanitation crews to return to collection operations more quickly.
6. Efficient Sewage and Sludge Transportation
The ISUZU truck is designed to handle liquid dirt, sewage, septic waste, and sludge, making it suitable for a wide variety of environmental sanitation applications. The large-capacity tank allows operators to collect substantial quantities of waste during each trip, which can improve productivity on large municipal or commercial sanitation projects.
Typical applications include septic tank cleaning, public toilet waste collection, sewage pit cleaning, municipal sanitation, industrial liquid waste handling, and maintenance of wastewater-related facilities.
7. Strong Tank Construction
The vacuum tank uses Q235B carbon steel with a specified wall thickness of more than 5mm, providing the structural strength necessary for repeated vacuum and transportation operations. The robust tank construction helps the vehicle withstand the mechanical stresses associated with filling, vacuum suction, liquid transportation, and discharge.
The combination of a heavy-duty chassis and reinforced tank structure makes the truck suitable for intensive sanitation work where reliability and long-term durability are important considerations.
8. Designed for Professional Sanitation Operations
With its 15 CBM tank, 28-meter suction range, powerful 350HP engine, large-capacity chassis configuration, and rapid vacuum and discharge performance, the ISUZU 15 CBM Toilet Vacuum Truck is designed for professional sewage collection and transportation.
Its combination of high-capacity liquid waste handling and strong road performance makes it particularly suitable for municipal sanitation, septic tank cleaning, public toilet maintenance, sewage contractors, industrial facilities, and environmental service companies that require an efficient heavy-duty vacuum truck for regular operations.
