Technical Specifications

Strengths and Characteristics

This sewage suction truck is configured for high-frequency sanitation work rather than occasional light-duty cleaning. The QINGLING ISUZU GIGA 6×4 chassis provides a stable platform for heavy tank loading, frequent stop-and-go operation and long working hours in city roads, industrial areas and mixed road conditions.

The 18–20m³ tank volume gives operators enough working capacity for daily sewer cleaning, sludge collection and wastewater transport while maintaining practical maneuverability for municipal and residential environments. The horizontal cylindrical tank design supports stable weight distribution, and the hydraulic lifting self-discharging function helps reduce manual cleaning time after waste collection.

The Weilong high-power vacuum sewage suction pump is selected for strong suction performance and fast waste collection. With an ultimate vacuum degree of approximately -0.095MPa, the system is suitable for thick sludge, feces, sewage and construction mud. For buyers who need trailer-based vacuum transport solutions, Luyi Auto also offers related vacuum tank truck and tanker trailer options.

Advanced Safety Systems & Compliance

Sewage suction work often involves unstable liquid-solid waste, narrow working areas, repeated braking and environmental safety requirements. For this reason, the truck is equipped with high-strength heavy-duty axles and a WABCO braking system to support stable braking under loaded conditions.

The tank system includes an overflow prevention valve, oil-water separator and anti-clog quick suction and discharge connectors. These components help reduce operational risk during suction, transport and discharge. The dual-control system combines hydraulic and pneumatic operation, with control stations arranged at the cab and rear part of the vehicle, allowing operators to manage suction and discharge work more conveniently on different job sites.

For export markets, configuration items such as left-hand drive or right-hand drive, emission standard, lighting, warning markings, tire type, braking system and documentation should be confirmed before production. Luyi Auto can discuss these details according to the buyer’s country, road conditions and sanitation operation requirements.

Our Craftsmanship & Quality Control

For sewage suction trucks, the most important manufacturing points are tank strength, sealing reliability, pump installation, pipeline layout, anti-corrosion treatment and the coordination between chassis and superstructure. Luyi Auto checks these items before delivery to reduce operating problems after the vehicle arrives at the customer’s site.

The tank uses 6mm thickened carbon steel as the standard material, with 304 stainless steel available for buyers who require stronger corrosion resistance. The tank body, suction and discharge connectors, lifting structure, hydraulic system and pneumatic control system are inspected as a complete working unit rather than as separate parts only.

Before shipment, technicians check welding quality, tank sealing, pump connection, suction and discharge pipelines, hydraulic lifting function, braking system, lighting system, tire condition, surface finish, anti-rust treatment and accessory completeness. Buyers who want to understand the production environment can view the Luyi Auto manufacturing facility.

Optional Configurations & Customization

Sanitation vehicles should be configured according to local waste type, disposal method, road width, operating climate, maintenance capacity and regulatory requirements. Luyi Auto can provide configuration recommendations before production instead of only offering a fixed standard model.

• Tank material: 6mm carbon steel or optional 304 stainless steel
• Drive side: left-hand drive or right-hand drive according to destination market
• Emission standard: Euro V / China VI configuration depending on market requirement
• Cleaning function: optional auxiliary engine high-pressure cleaning system
• Pipeline material: optional full stainless steel suction and discharge pipelines
• Cold-region use: optional tank heating and thermal insulation device
• Operation upgrade: optional wireless remote control system
• Exterior design: customized vehicle painting and customer logo printing
• Export support: documentation and shipment coordination according to destination requirement

If your project needs a different sanitation vehicle, tank trailer or liquid waste transport solution, you can review Luyi Auto’s full product range or send your working condition details through the inquiry form.

Packaging and Transportation

Before export shipment, the truck is cleaned, inspected and protected against corrosion. Exposed metal parts receive anti-rust treatment, and small accessories are packed and fixed to reduce the risk of movement or loss during transportation.

For overseas delivery, the vehicle can be shipped by RO-RO vessel, flat rack or bulk carrier depending on port conditions, shipping route and order quantity. Luyi Auto can coordinate pre-shipment inspection, export documents and shipping arrangements from major Chinese ports. Standard lead time is usually 15–30 working days after deposit, depending on chassis availability, superstructure configuration and customization requirements.

Why Choose Luyi Auto

FAQ

1. What type of waste can this sewage suction truck handle?
It is suitable for urban sewage, sludge, feces, construction mud and other solid-liquid mixed waste. If the waste contains strong corrosive chemicals or special industrial substances, please provide the media details before quotation so the tank material and pipeline configuration can be checked.

2. Can the truck be customized for local regulations?
Yes. Luyi Auto can discuss drive side, emission standard, lighting, warning markings, braking configuration, tank material and export documents according to the destination country. Final road-use compliance should be confirmed with local regulations before purchase.

3. What is the advantage of the hydraulic lifting self-discharging tank?
The hydraulic lifting tank helps discharge sludge and mixed waste more completely, reducing manual cleaning workload and improving turnaround efficiency after each suction task.

4. What should be checked if suction becomes weak during operation?
Weak suction is usually related to air leakage at hoses or valves, pipeline blockage, insufficient pump oil, worn pump parts or improper valve position. Operators should check hose tightness, clean pipelines regularly and maintain the vacuum pump according to the service schedule.

5. What daily maintenance is required?
Before operation, check vacuum pump oil, hose connections, valve sealing and pipeline condition. After operation, clean the tank and suction/discharge pipelines to reduce blockage, odor and corrosion. Worn sealing parts and hoses should be replaced in time.

6. What information should I send before requesting a quote?
Please send your destination country, drive side requirement, emission standard, waste type, expected tank volume, operating road condition, whether you need high-pressure cleaning, required tank material and order quantity. These details help Luyi Auto recommend a more accurate sewage suction truck configuration.
