Hongyan 6x4 17 m³ Vacuum Tanker with 5 m³ Water Tank

This SAIC Hongyan 6x4 vacuum tanker is built for city drainage departments and large septic and industrial cleaning contractors who need high volume and a flushing system on one truck. The tank body holds about 22 m³, divided into a 17 m³ sewage compartment and a 5 m³ clean-water compartment, so crews can loosen deposits with water and then vacuum the sludge on the same visit.

Power comes from a Yuchai 350 hp diesel engine driving through a 10-speed manual gearbox, with 11.00R20 18PR tires on three axles and a wheelbase of 4,700 + 1,400 mm. Gross vehicle weight is 25,000 kg and curb weight is 17,450 kg. The high-pressure system uses a 350 L/min pump supplied from the clean-water tank, and the rear-mounted hose reel carries the jetting hose. The Q235 carbon steel tank has 8 mm end caps, anti-rust treatment and an anti-corrosion, waterproof coating, plus a non-slip walkway on top. An anti-overflow valve, pressure gauge, liquid sight glass, working light and warning light are fitted, and a tank lifting system is available for unloading heavy sediment.

Typical work covers trunk sewer and storm drain maintenance, emptying large septic tanks and grease interceptors, and clearing industrial pits. At 10,200 × 2,550 × 3,750 mm, the truck is suited to main roads and depots rather than narrow lanes. Emission levels from Euro 2 to Euro 6 can be specified.
