Saving fuel is more important than ever, and with construction vehicles it is almost impossible to avoid frequent empty journeys, for example on the way back from a construction site. Therefore, in addition to a high payload, a low unladen weight is particularly important. The DHKA 350 Revolution tipper semi-trailer offers both: Fliegl achieves a payload of 31,000 kilograms with an unladen weight of just 4,000 kilograms with the vehicle on display. Depending on the equipment, an unladen weight of less than 4,000 kilograms is even possible - a record in the industry!
Lightweight construction and efficiency
The lightweight chassis with patented curved front end rolls on polished aluminium rims, the side walls of the aluminium body are made of 30 millimetre thick hollow chamber profiles and are only 1,450 millimetres high on the 25 cubic metre version. This means that the tipper trailer is lower than the cab - which also ensures lower air resistance, as does the flip-top sliding roof. When the roof is closed, the airstream no longer catches on the tailgate when the body is empty, which is also curved and reduces air resistance. Low rolling resistance, low fuel consumption and less tyre wear are ensured by the axles, which are laser-measured and precisely adjusted at the factory.
Body and details
The clever details of the tipper semi-trailer are impressive in everyday use: thanks to the special integrated mudguards, any spilled bulk goods fall straight onto the floor when loading - and not onto the road later. The conical and aerodynamically shaped Greenline troughs are 5 centimetres wider at the rear than at the front, so that no load gets stuck; thanks to the rubber seal, the membrane flap is virtually watertight, ideal for damp bulk goods. The double-joint hinge facilitates tipping by opening the tailgate particularly wide. Thanks to the electric drive, the inconvenient manual opening and closing of the roof is no longer necessary; the driver can operate the flip-top sliding roof either directly on the trailer or by radio remote control.
If the drive axle of the tractor unit loses traction on wet, muddy construction sites, the starting aid comes into play: the first axle is designed as a lift axle, which can be raised up to 30 per cent above the axle load. From a speed of 25 km/h, the axle automatically lowers again. Disc brake axles are used.
Safety
Good lighting contributes to greater safety, not only in the darker months of the year. Two LED headlights at the rear illuminate the rear working area; the multi-chamber rear lights with dynamic indicators, side marker lights as well as position and lane departure lights are also fitted in LED design. The aluminium hook-on ladder with "safety plus" also ensures greater work safety.
Durability
Robustness counts in tough everyday construction site work, and Fliegl proves that lightweight construction and durability are not mutually exclusive: The 5 millimetre thick aluminium plates of the trough are particularly light, but with a hardness of 110 Brinell, the surface is very hard and abrasion-resistant - this ensures low wear even with abrasive goods.
Fliegl offers a 10-year warranty against rusting through of the frame. Fliegl is the only vehicle manufacturer to also focus on the air suspension mounts; they are located at the lowest point of the vehicle and are permanently exposed to dirt and moisture in everyday construction site use. Thanks to the hot-dip galvanisation of the air suspension arms, nothing stands in the way of many years of operation.
