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.
Aluminum 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.
