The patented system minimises rolling movements and the risk of the trailer tipping over on uneven ground when the body is raised. For this purpose, two robust fold-out metal supports create a connection between the last axle and the frame when tipping - thus absorbing lateral rocking movements. After lowering, the supports automatically return to their original position. The system, which weighs just 26 kilograms, works purely mechanically, which protects the environment and saves costs as no complex hydraulics are required. The system also takes over the function of fixing the height, which simplifies the transfer of asphalt to a paver, for example.
The system also offers an approach aid. This can be useful if the rear wheels of the lorry have little or no grip on slippery surfaces. The first axle of the three-axle vehicle can be raised, which shifts 2.8 tonnes (10.7 percent of the trailer weight) onto the fifth-wheel plate when tipping, thus ensuring greater stability. When moving off with a load, as much as 6.7 tonnes press on the drive axle - resulting in more traction on loose or slippery surfaces. From a speed of 25 km/h, the axle automatically lowers again.
As the air bellows are no longer fully compressed by the drive-on system, the rubber blocks inside last much longer. The same applies to the arms of the air suspension mounts, which are located at the lowest point and are permanently exposed to dirt and moisture. Fliegl is therefore the only manufacturer to galvanise the air suspension arms and offers a 10-year anti-rust guarantee.
Exclusive to Fliegl: Every single axle of every trailer is precisely adjusted in the factory using a modern laser measuring system. As a result, the trailers run with absolute tracking accuracy, have no more unnecessary tyre wear and offer lower fuel consumption. Trailer efficiency defined by Fliegl. From the roof to the wheels: Vehicle concepts thought through to the end.
