1. Product Overview

Core Product Keywords: FAW JH6 6×4 20CBM Sewage Suction Vacuum Truck, FAW Heavy-duty Sanitation Truck, 20CBM Large-capacity Vacuum Sewage Truck, Municipal Sludge Suction Vehicle, Large-volume Sewage Disposal Equipment.

Vacuum Tanker truck (commonly known as Vacuum Sewage Truck) is a special sanitation vehicle equipped with vacuum pump, used to suck, transport and discharge sewage, sludge, mud and wastewater.

A Vacuum Tanker truck is a dedicated municipal sanitation vehicle designed with a high-performance vacuum pumping system. It creates negative pressure inside the sealed tank to suction sewage, sludge, slurry, sewage waste and other liquid-solid mixtures from sewers, septic tanks, drainage pipes and sewage pits. The collected waste is stored in the tank and transported to designated treatment areas for unloading. This vehicle is widely applied in urban sanitation, environmental protection, municipal engineering and rural sewage treatment.

Body Structure Description

Its storage tank is constructed with thickened high-strength carbon steel integrated stamping and welding structure, adopting integral sealing and pressure-resistant design to bear negative pressure suction and hydraulic discharging.

Core Advantages

1. High working efficiency：Adopts vacuum negative pressure suction mode, with fast suction and discharge speed, which can quickly clean sewage, sludge and blockages.

2. Wide application range：Suitable for sewer, septic tank, sewage pit and other scenarios, capable of handling various liquid and solid mixed wastes.

3. Good sealing & environmental protection：The fully sealed tank avoids leakage and odor overflow, reducing secondary pollution.

4. Flexible & labor-saving：Integrates suction, storage and transportation, reducing manual operation and lowering labor costs.

5. Stable performance：Equipped with mature vacuum and hydraulic systems, with stable operation and long service life.

2. Working Principle

The complete working system of FAW JH6 6×4 20CBM sewage suction truck consists of three core modules: mature FAW JH6 6×4 heavy-duty chassis power system, industrial-grade vacuum pumping assembly and super-large 20CBM pressure-resistant fully sealed storage tank.

After engine startup, the power take-off extracts power from original FAW JH6 heavy-duty chassis to drive the vacuum pump to run continuously. The vacuum pump discharges air inside the sealed tank to form stable negative pressure. Relying on atmospheric pressure difference, all kinds of sewage, sludge, slurry and liquid-solid mixed waste are automatically sucked into the 20CBM large-capacity storage tank from sewers, septic tanks, drainage pipes and sewage pits.

Benefiting from integral pressure-resistant and sealing structure, the thickened carbon steel 20CBM tank can bear long-term negative pressure operation and prevent sewage leakage and odor overflow. After waste collection is completed, operators control the hydraulic system to finish automatic unloading. The whole process realizes mechanized integration of suction, storage, transportation and discharging. Equipped with streamlined FAW JH6 comfort cab and heavy-duty 6×4 drivetrain, the truck owns strong power output, outstanding trafficability and ultra-large loading capacity, perfectly adapting to high-intensity, large-volume municipal sanitation operations.

3. Daily Application Scenarios

Urban Municipal Sanitation: City sewer dredging, drainage pipeline blockage removal, public septic tank and sewage pit regular cleaning
Environmental Protection Projects: Polluted domestic sewage disposal, urban black-odor river remediation, water body sludge cleaning
Municipal Engineering Operation: Construction site wastewater and mud disposal, foundation pit sewage suction
Rural Sewage Treatment: Village domestic sewage collection, rural ditch desilting, decentralized sewage disposal
Public Facility Maintenance: Park, scenic spot and residential community sewage pipeline daily maintenance

4. Comparison with Traditional Sanitation Vehicles

Vs Manual Sewage Cleaning: Traditional manual dredging relies on handwork and simple pumping tools, featuring low suction efficiency, huge labor consumption and serious odor leakage, causing urban secondary pollution. This SINOTRUK HOWO sewage suction truck adopts full-mechanical operation, saving labor cost and optimizing working environment.

Vs Ordinary Water Transport Trucks: Common Water Tank Trucks only support simple liquid transportation, without negative pressure suction function, unable to dispose viscous sludge and solid-liquid mixed waste. This professional SINOTRUK HOWO sewage suction truck equips dedicated industrial vacuum system, integrating suction and transportation functions to meet comprehensive sanitation demands.

Vs Ordinary Medium & Small-volume Sewage Trucks: Common sanitation trucks are equipped with 8-12CBM small tank, requiring frequent round trips and wasting fuel cost and working time. This FAW JH6 6×4 model equips standard 20CBM super-large capacity tank, drastically improving single transportation efficiency; reliable FAW chassis delivers stronger bearing capacity, suitable for long-term heavy-duty operation.
