Dongfeng Duolika 4x2 4 m³ Low-Profile Sewer Jetting Truck

This Dongfeng Duolika 4x2 sewer jetting truck is designed for building maintenance contractors and municipal crews who service drains, grease traps and sumps under residential towers, malls and underground garages. Its overall height of 2,200 mm lets it drive down ramps and under ceilings that stop standard vacuum trucks, while the short 5,995 mm body keeps turning easy in tight car parks.

The 6 m³ tank is divided into a 4 m³ sewage compartment and a 2 m³ clean-water compartment. Clean water feeds the high-pressure hose reel for jetting blocked lines, and the vacuum side uses an SK-9 pump rated at 420 m³/h or an optional SK-12 pump rated at 720 m³/h, with a suction depth of at least 9 m. The light-duty chassis has a 3,308 mm wheelbase, a 5- or 6-speed synchronized manual gearbox, air brakes with ABS and 7.00R16 steel radial tires. Engine choices are a Yuchai 140 hp (103 kW) unit or a 115 hp unit, and the single-row cab has air conditioning, power windows and central locking.

Typical work includes flushing basement drainage lines, emptying sewage lifting pits and grease interceptors, and clearing short sections of blocked sewer before vacuuming the loosened sludge. Gross vehicle weight is 7,360 kg with a curb weight of 5,400 kg. Emission levels from Euro 2 to Euro 6 can be specified, and the pump size can be chosen to match the depth and sludge type of the sites served.
