A unique shear system, originally developed and used in agriculture, has also been built since 2008 for transporting road construction products such as sand, gravel, soil, (greasy) clay, (crushed) rubble and much more.

Because the trailer is insulated with rigid foam panels, you have virtually no heat loss on the outside and the hot asphalt is better maintained at temperature which improves quality.
Since 2012, the system has been modified so that asphalt can also be transported. The Fliegl shear system has been in existence for 21 years and is a unique further developed product that fits in very well with practice. Speaking is Stuart Lawrence, driver/ shear specialist at Van Eeuwijk BV Velddriel. He drives the Fliegl shear trailer daily and wouldn't want it any other way. "It is a super fine trailer, I am very satisfied with it!" When asked if he could list the biggest advantages Lawrence replies, "Maneuverable, safe and easy to clean." The company Lawrence works for is distinguished, among other things, by its versatility. In order to be able to offer an even wider range of work towards the market, it was decided to add a Fliegl push-off trailer to the fleet.

"With the Fliegl shear trailer you can unload in places where you can't unload with an ordinary tipper. Under overpasses, in tunnels, near high-voltage cables or, for example, in somewhat narrower streets where there are protected trees." The trailer also offers many other advantages. Lawrence: "First of all in terms of safety: because of the horizontal unloading, there is no longer any danger of falling over. In addition, it works many times more efficiently: I only have a very limited number of downtime hours because the bucket is always clean after unloading, even with ZOAB, OPA, SURF asphalt and very sticky clay, for example. This is because the contents of the bin are pushed out by the shear system and the bottom and walls are scraped clean. An additional advantage is that you can also bring back a return load such as milling asphalt, even when the bucket is still warm. And last but not least, the advantages for transporting asphalt." Research -by Fliegl in cooperation with TU Vienna (A) and TU Darmstadt (DE)- among others, showed that when using the Fliegl shear system, the segregation of bitumen during transport is greatly reduced, which means that all layers of asphalt in the bucket enter the asphalt paver at the same time dosed. This results in a much longer service life of the asphalt.
