Sv: AL-KO Bakaxel
Så vitt jag förstår så går det använda en verkstadsdomkraft där axeln sitter bultad mot ramen och där skall ev. pallbock även stå.

There are some myths about jacking a caravan that’s built on an Al-Ko chassis. Which jacks can be used? Where should they go? I contacted Paul Jones, the marketing manager of Al-Ko in the UK, for definitive answers.
There are various types of jacks, but Jones says his company recommends using its own side-lift model, which is designed for the chassis and has specific mounting points. Other products do as well, making them suitable. However, no alterations to the chassis must be made, because this would invalidate the van’s warranty, and can weaken the chassis structurally.
Set the side-lift aside
There are occasions, though, when the use of the side-lift jack is not practical, such as when a mover is fitted to the rear of the caravan axle. This is more likely on a twin-axle caravan when a 4x4 system is fitted.
The second option is to use a trolley jack. This will generally have quite a wide head and is thus suitable for using on the chassis. It must be placed under the chassis plates directly (or as near as possible) beneath the axle tube. The chassis plates are welded to the axle tubes and are part of the larger axle assembly.
However, a trolley jack cannot be used on any part of the chassis because that could cause distortion. As with alterations to the chassis, this may weaken the structure of the frame.
As a last resort, a scissor jack with a flat top may be used and placed in the same place as a trolley jack, but great care must be taken when using one because its much narrower footprint may cause instability.
If axle stands are to be used, they should be placed directly beneath the axle tube itself, as near to the chassis as possible. The reason for this is not only for stability, but also due to the construction of the axle itself. In essence, the outer ends of the axle tube contain the compressed rubber and other suspension components, thus filling the void within the tube. However, further towards the centre there is nothing inside the axle tube, so there is potential for the tube to be crushed or its shape distorted.
