Yes, for a reason. When driving a trailer with load on in the terrain, the frame meets strong bending forces, which the single beam contruction can take better than a contruction with two beams. The construction is planned to be flexible in determined places. Also unloading the last logs is easier and quicker in single beam trailer.

The front screen supports stiffen the trailer's front end, which helps front screen to withstand justification of the log bundles against the screen. The supports also stop first posts to turn inside.

All trailers have hydraulic articulated drawbar. The smallest trailer (KESLA 82) has one cylinder hydraulic drawbar. All other trailers have a hydraulic articulated drawbar with two cylinders. The moving angle of articulation is 33-40 degrees. It makes moving easier especially when thinning.
