How do I calculate whether my load needs a low loader or a standard flatbed?

Add the load's height to the trailer's deck height. A standard flatbed deck at 1,400 mm plus a 3.0 metre tall excavator reaches 4,400 mm total — overheight against the practical 4.0 metre road clearance threshold on most European routes. The same excavator on a low loader deck at 750 mm reaches 3,750 mm total — within clearance. Any load whose height plus the flatbed deck height exceeds 4,000 mm requires a low loader. Go Trans confirms the correct trailer type at the point of quoting based on the load's declared height and dimensions.
