Flatbed
Start with deck length, load placement, axle distribution and cab-to-trailer clearance.
Read the guide HIGHWAYTRAILERS.CAStep deck
Compare deck height, gooseneck geometry and the loaded combination’s height.
Read the guide HIGHWAYTRAILERS.CARGN / equipment hauling
Check neck compatibility, fifth-wheel loading, wet-kit requirements and the complete axle layout.
Read the guide HIGHWAYTRAILERS.CAHow trailer capacity works
Review the tractor, coupling, trailer, tyres and load as one combination.
Read the guidePulling a trailer
Confirm build-specific combination, axle, tyre and coupling ratings, kingpin and service connections, clearance and actual axle weights. GVW is the loaded truck; GCW is the loaded combination. Neither is trailer payload.
Moving the tractor as cargo
Give the carrier measured length, exterior and mirror widths, height, ground clearance and transport weight. Assess deck access, breakover, loaded height and securement together.
Deck height & loaded height ↗There is no single “HX towing capacity”.
The model badge, artwork and catalogue option selectors cannot rate an individual combination. Obtain the actual build limits and scale weights.
