Trombone Trailer

Trombone Trailer

Trombone trailer is a name for a flat trailer which extends when required to carry long loads. Trombone trailers may also be called:

• flat extender trailers
• flat extending trailers
• platform extender trailers
• platform extending trailers

Trombone trailers are built around a central steel box beam which carries a second beam within. The inner beam extends telescopically and is pinned in an extended position.

Normally a trombone trailer splits a few metres behind the headboard, providing deck surface on both sides of the split, to enable secure loading and lashing of the burden.
