With an unladen weight of 9,400 kg, the payload comes to 34,100 kg. At 11.90 m long, 2.55 m wide, with six wheels on a 9.12 m wheelbase, the Janmil sits on a long, multi-axle chassis that spreads the high gross weight across several axles and is built for bulky long goods or bulk cargo.
Category O4 trailers are generally fitted with an air brake system across several axles, with air suspension common at this size to keep the load steady on long journeys. Towing in a combination requires licence category C1E or CE in the EU, depending on the combination's gross weight. The long, six-wheel build spreads the axle load evenly and is typical for long-haul transport behind heavy tractor units, where the load itself often dictates the trailer's length.
When buying a used Janmil, check all axles for even wheel-load distribution, the brake system including its lines for leaks, and the axle bearings for play. The frame deserves particular attention for twisting and cracking, especially around the axle mounts, given the long build. Depending on which year within the long production span, it is also worth checking for earlier repairs and the condition of the suspension bellows.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
