M1 Engineering Limited – other models: the collective page of trailers outside the named ranges AL/169/16, CR/643/17 and CR/650/17, 6,960 to 8,700 kg unladen weight, 38,000 to 43,500 kg gross weight

The register lists here 3 versions with unladen weights of 6,960 to 8,700 kg, gross weights of 38,000 to 43,500 kg, lengths of 12,880 to 13,110 mm and a width of 2,550 mm.
With gross weights of 38 to 43.5 tonnes, all three versions sit in the upper range of semi-trailer and articulated-combination weights permitted in Europe, used for heavy long-haul transport. Driving such combinations requires a category CE licence, and lengths of around 13 metres match the scale typical of semi-trailers.
On a used example, axle and braking-system condition, the function of the air brake and the fifth-wheel or towing coupling, rust and cracks on frame and kingpin, and the state of landing gear, tyres and rims all count. Parts usually run through independent commercial-vehicle workshops; on the heaviest version at 43.5 tonnes gross, checking the frame welds is also worthwhile. It is also worth comparing the VIN and the registration document against the trailer's data plate. Before buying, a test tow is also worthwhile, checking tracking, braking behaviour and noises while under way.

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.
