HOWO 8×4 Sewer Cleaning & Vacuum Truck – Heavy-Duty Dual-Functionality with Precision Engineering
Overview
The HOWO 8×4 Sewer Cleaning & Vacuum Truck is a powerhouse solution designed for large-scale sanitation, industrial waste management, and emergency response operations. Built on the robust HOWO NX chassis, this vehicle combines unmatched payload capacity, advanced cleaning/vacuum systems, and operator-centric design to meet the rigorous demands of global clients. With rigorously validated specifications, it ensures reliability and compliance for international markets.
Key Features
1. Robust HOWO NX Chassis
Heavy-Duty Foundation: Engineered for extreme workloads, the HOWO NX 8×4 chassis provides exceptional stability, load-bearing capacity, and durability in harsh environments.
Ergonomic Cab Design: Features a modern, aerodynamic exterior and a spacious, driver-focused interior with ergonomic controls, climate control, and noise-reduction technology for enhanced comfort during extended operations.
2. High-Performance Powertrain
WP10H400E62 Engine: Delivers 400 HP (294 kW) with optimized torque output for heavy-duty tasks, ensuring high efficiency and compliance with Euro VI/Emission Stage V standards.
HOWO 12-Speed Manual Transmission: Designed for seamless power delivery, reduced shifting effort, and enhanced durability in stop-and-go urban or off-road conditions.
3. Dual-Compartment Stainless Steel Tank System
Independent Tank Design:
Clean Water Tank: Effective volume of 11.05 CBM (Straight section: 3,100mm length × 2,300mm diameter), constructed from stainless steel for corrosion resistance and longevity.
Waste Tank: Effective volume of 13.81 CBM (Straight section: 3,960mm length × 2,300mm diameter), built with reinforced stainless steel to withstand abrasive sludge, chemicals, and high-pressure operations.
Total Tank Dimensions: 7,100mm (length) × 2,300mm (diameter).
Safety Compliance: Independent tanks ensure balanced weight distribution and safe handling; simultaneous full loading is restricted to maintain stability and operational safety.
4. Advanced Cleaning & Vacuum Capabilities
High-Pressure Cleaning System: Equipped with a high-flow water pump (customizable pressure up to 280 bar) for efficient pipe descaling, surface cleaning, and debris removal.
Vacuum System: Features a high-power vacuum pump with a suction depth of up to 25 meters (optional upgrades available), capable of handling sludge, liquids, and semi-solid waste from sewers, tanks, or industrial sites.
5. Heavy-Duty Tires & Safety
12R22.5 18PR Tires: High-load radial tires provide superior traction, puncture resistance, and stability on uneven terrain or slippery surfaces.
Integrated Safety Systems: Includes tank pressure monitoring, overload alerts, and an emergency shutoff valve to prevent equipment damage and ensure operator safety.
Applications
Municipal Sewer Networks: Clear large-scale blockages and maintain urban drainage systems.
Industrial Waste Handling: Manage chemical residues, oil sludge, and hazardous byproducts.
Disaster Response: Rapid deployment for floodwater drainage or contamination control.
Infrastructure Projects: Clean construction sites, tunnels, and wastewater treatment plants.
Why Choose This Truck?
Unmatched Capacity: Largest tank volumes in its class, ideal for high-demand operations.
Premium Durability: Stainless steel tanks and reinforced chassis ensure a 10+ year service life.
Operational Efficiency: High-pressure cleaning and deep suction capabilities reduce job completion time.
Global Compliance: Meets international emission and safety standards for seamless deployment.

1. Slowly insert the suction pipe into the sewage well or sewage pool. The insertion depth should be appropriate to avoid the pipe mouth being blocked.
2. Start the vacuum pump and control the suction speed by operating the valve. Pay attention to observing the liquid level of the suction tank.
3. During the suction process, always pay attention to the working sound and temperature of the vacuum pump. If there is any abnormality, stop the machine immediately for inspection.
Discharge operation:
1. After arriving at the designated discharge location, stop the vehicle and pull the handbrake.
2. Open the discharge valve and slowly discharge the sewage. Pay attention to controlling the discharge speed and direction.
3. After the discharge is completed, close the discharge valve and clean the discharge pipe.
