> Belly dump--A type of dump truck pulled by a semi-truck
Is the phrase "semi-truck" actually used in Alaska?
The prime mover of a semi-trailer rig is, in trucker's jargon, a "tractor",
hence the phrase "tractor-trailer". A "semi-trailer" is (MWCD10) "a
freight trailer that when attached is supported at its forward end by the
fifth wheel device of the truck tractor".
>From context a "semi-truck" would be a truck equipped with a fifth wheel for
pulling a semi-trailer, but it's a new one on me.
Another error in "Belly dump--A type of dump truck pulled by a semi-truck" is
that a dump truck, whether rigid-chassis or tractor-trailer, is a
self-propelled vehicle. The writer obviously meant a semi-trailer with
retractable openings on its bottom for dumping aggregate or other bulk
Whoever the writer is, she is obviously neither a construction worker nor
married to one.
