Construction machinery trailers: tandem or single axle for your machine?

A single axle is usually enough for smaller compact excavators, while a tandem axle becomes the sensible choice for wheel loaders and larger construction machinery. This comparison helps you decide based on machine weight.

Single axle for compact excavators

A single-axle trailer like the BM 2000 Kompakt offers enough payload for mini excavators and smaller compact machines, while giving better manoeuvrability and a lighter trailer overall.

Tandem axle for wheel loaders and larger excavators

For heavier machines like wheel loaders or larger excavators, a tandem-axle trailer like the BM 3500 or the BM 6000 Tandem offers considerably more payload and distributes the weight more evenly across two axles – important for stability under full load.

Effect on manoeuvring and turning circle

A tandem-axle trailer is generally less manoeuvrable than a single axle, especially when reversing on tight job sites. Weigh this drawback against the higher payload, particularly if you regularly work in confined spaces.

Conclusion

Choose the axle configuration based on the actual operating weight of your heaviest machine, not the average of your fleet. When in doubt, a tandem axle offers more headroom for future purchases.
