Semi-trailer or Van trailer, Box
trailer
A
semi-trailer is a trailer without a front axle.
A large proportion of its weight is supported by a road tractor, a
detachable front axle assembly known as a dolly, or the tail of
another trailer. A semi-trailer is normally equipped with landing
gear (legs which can be lowered) to support it when it is
uncoupled.
A road tractor coupled to a semi-trailer is often called a
semi-trailer truck or
semi in the US and an articulated
lorry or
artic in the UK. The fifth wheel on a truck
connects to a semi trailer Kingpin. Kingpins come in many guises,
however the most common within the UK market is the 2.0" (50.8mm)
EEC approved type. This Kingpin is fully interchangeable and, given
a strict maintenance schedule, it should last the life of a
trailer.
In Australian English, the tractor unit is usually referred to as a
prime-mover; and the combination of a prime-mover and
trailer is known as a
semi-trailer or
semi.
Semi-trailers with two trailer units are called
B-Doubles
(or in American English often just
doubles), and in some
cases (especially when there are three or more trailers),
road
trains. A B-double consists of a prime mover towing two
semi-trailers, where the first semi-trailer is connected to the
prime mover by a fifth wheel coupling and the second semi-trailer
is connected to the first semi-trailer by a fifth wheel coupling. A
road train means a combination, other than a B-Double,
consisting of a motor vehicle towing at least two trailers
(counting as a single trailer a converter dolly supporting a
semi-trailer)
