Key facts

Convincing advantages.

  • Maximum load volumes thanks to low loading height and wide low bed
  • Patented low-mounted air suspension unit for maximum width and depth between the wheels
  • Low tare weight from rigid lightweight construction
  • Transport of wall elements and goods also possible without swap-body platform
  • EPD coating (sand blasted, cathodic immersion priming, coating in RAL colors)

Understated but stacked high – the modular expandable X-SW300 semitrailer.

The X-SW series counts as one of the capable and most sold extendable semitrailers for wall element transport. The core of the X-SW strategy is, with an especially low design height, to create maximum loading height and flexibility for your load. Two or three steering axles add the highest level of steering ease and stability.

Wood frame construction companies and builders appreciate the X-SW series, as the base version can be upgraded at any time to a swap system.

Whether with or without swap-body frames, for use as a low loader or as a flexible transport solution with our extendable frame, X-SW semitrailers adapt to your transport needs cost effectively as needed. Thanks to the flexible and modular design, we can meet your individual requirements and make the necessary changes.
