Eli5: Why do large dump trucks carrying large dump trailers have such a long hitch?

377 views

Noticed a large dump truck driving around a construction site at the airport and the dump trailer it was carrying had a hitch almost as long as the trailer. Why is this? Maneuverability? Helps with leverage when dumping the trailer?

I’d have to see the one you’re talking about but the dump trucks I know have quite a lot of overhang behind the rear tyres. The tyres are where the pivot point is when it’s turning. If the trailer is too short, the rear part of the truck will collide with the trailer when making turns.
