SEM SB1: 1 axle steered

The SEM SB1 steering system steers 1 axle on your trailer. The main benefit of an SEM SB1 system is its simplicity. Trailer steering is based on a single bar connected to the axle group and a front unit which not only makes the system extremely robust but also reduces the number of components to a minimum.

The system can be configured for various types of trailers – from 1- up to 3-axle – to enable the steering of a single axle from the axle group.

SEM single bar trailer steering

Why choose a single bar steering system?

  • The trailer will follow the line taken by the truck more closely so that its movement is more streamlined on bends.
  • Because the trailer follows the line taken by your truck more closely, it also becomes easier to manoeuvre.
  • The improved ease of manoeuvring and the saving on space when taking a bend increases the usability of your trailer.
  • Increasing usability has a direct positive effect on the efficient use of your transport equipment.
  • A trailer steering system reduces the friction when taking a bend.
  • As a result of that reduction in friction, less energy is required leading to savings on fuel consumption and tyre wear.
  • The reduced energy consumption brought about by a steering system on a trailer in turn leads to lower emissions including CO2. Therefore it is better for the environment.
  • Reduced particulate emissions.
