Dongfeng Cleaning Suction Truck: Dual-Function Excellence for Modern Sanitation
Introduction to the Cleaning Suction Truck
In the realm of urban maintenance and industrial waste management, efficiency and reliability are non-negotiable. The Cleaning Suction Truck represents the pinnacle of dual-function sanitation technology, combining high-pressure cleaning with powerful vacuum suction in a single, robust vehicle. Built on the proven Dongfeng Class II chassis (EQ1145SJ8DCD series), this machine is engineered to tackle the most challenging tasks, from unclogging municipal drainage systems to industrial spill response. By integrating two independent tanks and two specialized pumping systems, it offers a comprehensive solution for municipalities and contractors seeking to optimize their fleet and reduce operational costs.
Key Features and Technical Advantages
Our Cleaning Suction Truck is not just a vehicle; it is a highly engineered system designed for maximum performance, durability, and safety.
Dual-Tank Independent System
The core innovation lies in its segregated tank assembly, which prevents cross-contamination and allows for versatile operation.
Sewage Tank: A cylindrical tank with a total capacity of 7.45 cubic meters (effective volume: 7.10 m³) designed to hold liquid sewage with a density of 800 kg/m³. It is equipped with a hydraulic lifting mechanism for efficient dumping.
Clean Water Tank: Two shaped tanks flank the sewage tank, providing a combined total capacity of 4.20 cubic meters (effective volume: 4.00 m³) for clean water (density 1000 kg/m³). Dimensions: 3980x580x1080 mm.
Operational Flexibility: The clean water and sewage tanks are independent and cannot be fully loaded simultaneously to ensure safe axle load distribution. A strategically placed ball valve connects the two tanks, allowing for the transfer of water from the clean tank to the sewage tank if extended suction operation is required.
High-Performance Vacuum Suction System
Designed for rapid and deep waste extraction, the vacuum system is the heart of the suction functionality.
Powerful Vacuum Pump: Features a maximum flow rate of 720 m³/h and achieves a maximum vacuum degree of 92%, ensuring fast suction speeds and the ability to handle heavy sludge.
Exceptional Suction Depth: Capable of full-tube suction up to 6 meters and half-tube suction up to an impressive 8 meters, making it suitable for deep manholes and underground pipelines.
Robust Components: The system includes an anti-overflow device for water-gas separation, primary and secondary oil-gas separators, a four-way valve, and an overpressure safety valve to protect the pump and ensure long service life.
Efficient Material Handling: Equipped with a 102mm diameter suction pipe to efficiently draw in liquid waste and debris.
Powerful High-Pressure Cleaning System
The cleaning function transforms this truck into a mobile pipeline maintenance unit.
High-Pressure Water Pump: Delivers a maximum pressure of 22 Mpa and a flow rate of 215 L/min, generating a powerful jet capable of breaking through the toughest blockages.
Integrated Waterway: The system utilizes the dedicated clean water tank and routes high-pressure water through a hydraulically controlled hose reel to the rear, enabling effective pipeline dredging and surface cleaning.
Robust Hydraulic and Chassis Systems
Built on a reliable Dongfeng platform, the entire vehicle is designed for demanding daily use.
Comprehensive Hydraulic Control: A dedicated hydraulic system (tank, gear pump, valves, cylinders, and motor) controls the lifting of the sewage tank, the opening and closing of the rear door, and the retraction of the water hose reel.
Durable Chassis: The Dongfeng EQ1145SJ8DCD chassis features a 3800mm wheelbase, 8.25 steel wire tires, and an 8-speed gearbox. The engine delivers 121kw of power and meets the National VI emission standards, combining power with environmental responsibility.
Safety and Compliance: The vehicle is equipped with an ABS system (Model: ABS/ASR-24V-4S/4M from Xiangyang Dongfeng Longcheng Machinery Co., Ltd). Side and rear protection devices are made of Q235A carbon steel, with a rear protector cross-section of 55x120mm and a ground clearance of 460mm. A rear night light is installed for work visibility but is disabled during driving for road safety.
Primary Application Scenarios
The versatility of the Dongfeng Cleaning Suction Truck makes it an invaluable asset across multiple sectors.
Municipal Drainage and Sewer Maintenance
This is the vehicle's primary role. It is deployed by sanitation departments to:
Clear Blockages: Use high-pressure water jets to break up grease, roots, and sediment in pipes, then immediately vacuum the debris into the sewage tank.
Routine Maintenance: Perform scheduled cleaning of storm drains and sewer lines to prevent urban flooding and maintain public health infrastructure.
Deep Cleaning: Its 8-meter half-tube suction depth allows it to access deep mainlines and lift stations that standard trucks cannot reach.
Industrial Waste Management
Factories and industrial plants generate various liquid wastes that require safe and efficient removal.
Spill Response: Quickly contain and recover chemical or oil spills, mitigating environmental hazards.
Tank and Pit Cleaning: Remove sludge and wastewater from settling tanks, holding ponds, and sump pits.
Process Waste: Handle non-hazardous liquid byproducts from manufacturing processes.
Agricultural Waste Handling
Farms benefit from the truck's ability to manage large volumes of organic waste.
Manure Management: Efficiently vacuum liquid manure from lagoons and storage pits for transport to treatment or field application.
Fertilizer Transfer: Handle liquid fertilizers, thanks to the pump's design for handling viscous materials.
Construction and Site Rehabilitation
Construction sites often require specialized cleaning to stay on schedule and comply with regulations.
Dewatering: Remove standing water from excavations and trenches.
Slurry Cleanup: Vacuum up slurry from concrete cutting, coring, and drilling operations.
Site Rehabilitation: Clean up mud and debris from site roads and work areas before project completion.

Frequently Asked Questions (FAQ)
Q1: What is the actual usable capacity of the tanks?
The sewage tank has a total geometric volume of 7.45m³, with an effective working volume of 7.10m³. The clean water tank has a total volume of 4.20m³, with an effective volume of 4.00m³. Please note that due to vehicle axle load distribution and safety regulations, the two tanks are independent and cannot be completely full simultaneously during transport.
Q2: Can the clean water be used to supplement the sewage tank during operation?
Yes, the two tanks are connected by a ball valve. If you are on-site and need to extend your suction operation without returning to base, you can open this valve to transfer water from the clean water tank into the sewage tank. This is a key feature for maximizing operational efficiency.
Q3: What are the maintenance requirements for the vacuum pump?
The vacuum pump is designed for durability but requires routine checks. Operators should regularly inspect the oil levels in the primary and secondary oil-gas separators. It is also important to check the anti-overflow device for blockages and ensure all vacuum pipeline connections are airtight to maintain maximum suction performance. The hydraulic system for the tank lift and door should also be checked for leaks regularly.
Q4: What are the key safety features on this vehicle?
*Safety is a priority. The truck is equipped with an ABS braking system (ABS/ASR-24V-4S/4M). It features side and rear protective devices made of Q235A carbon steel. The rear door of the sewage tank is hydraulically controlled for safe opening and closing. Additionally, while a work light is installed at the rear for nighttime operations, it is interlocked to be inoperable during road transit to prevent glare for other drivers.*
