Oil tank
semi trailers, or semi trucks for short, have proven to be very versatile
vehicles, with a multitude of uses besides transporting cargo. Since there are
now semi truck manufacturers that produce different types of beds or attachments,
you can now make use of one semi to do tons of tasks, and can be a great
business venture.
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. The fifth wheel on a truck connects
to a semi trailer Kingpin which is fully interchangeable and given strict
maintenance is adhered to, it should last the life of a trailer.

alloy tanker semi trailer with two trailer units are B-Doubles or 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).
Advantages
1. In road haulage, semi-trailers predominate
over full-trailers because of their flexibility.
2. The trailers can be coupled and uncoupled
quickly, allowing them to be shunted for loading and to be trunked between
depots.
3. In the event of a breakdown, a tractor
unit can be exchanged quickly and the load delivered to its destination without
undue delay and without having to trans-ship.
4. It is also possible to use a dolly to tow
a semi-trailer behind a rigid truck, or behind another semi-trailer.
5. Compared with a full scale trailer, a
semi-trailer attached to a tractor unit is easier to reverse, since it has only
one turning point (the coupling), whereas a full trailer has two turning points
(the coupling and the drawbar attachment).
6. Compared with a rigid vehicle, a
semi-trailer truck has a turning circle smaller than its overall length making
it more maneuverable.
7. Because of the longer overall length of
the cargo bed, a semi-trailer can haul longer objects (tree trunks, pipings,
beams, railway track) than a full trailer. Given equal lengths of the
composition, a semi-trailer has greater load capacity, since the drawbar adds
to the overall length of the composition. A semi-trailer has a better ratio
between tare and cargo weights.
8. A semi-trailer leads to more weight on the
driven axles of the tractor than a truck plus trailer combination, an advantage
on snow or mud.
Having a semi truck can be an excellent
investment, especially if your business requires you to have a reliable mode of
transport for inventory, machinery, and others. If you are considering buying a
