There are many types of means of transport including land . These operate by means of vehicles that can move on the surface of the earth and most of them have wheels on rails to be able to move. There are several types of land transport that function as a secondary means of transport, one of them is the trailer .

What is a trailer?

trailer is a type of vehicle that does not have propulsion mechanisms and that must be towed by another vehicle in order to function . They must also have braking mechanisms , lights and indicators that work together with the vehicle that guides them.

The trailer is a type of cargo transport that is mobilized by land and that does not have any motor and also does not have its own traction for this reason, it must always be driven by a different vehicle to be able to move. It is a type of vehicle that has been specifically built to be able to circulate being towed by a motor vehicle.


Trailer Features

Trailers have several characteristics, including the following:

  • It is a type of cargo vehicle.
  • It does not have any type of motor .
  • So generally , the maximum capacity is set to 750 kilograms.
  • It cannot move by itself because it needs the direction of another vehicle, which can be a car, motorcycle, or even larger vehicles such as tractors.
  • It must have wheels , a chassis , a surface where the load is placed and depending on the load, it must have brakes.


The word trailer comes from the verb tow which comes from the Latin language ” remulcare “, from the Greek word rymoylkein , a word that is composed of ” ryma ” which means rope and ” olkós ” which means traction. The birth of the trailer was in the hands of Alexander Winton , a man who was dedicated to the manufacture of cars and who also owned a well-known company, the Winton Motor Carriage Company , located in Cleveland. It was he who observed how difficult it was for customers to be able to carry things from one place to another without the vehicle being damaged or having failures and that is how the trailer originated.


After the trailer was created by Alexander Winton, other manufacturers in the area and around the world began to create and design their own trailer systems , which caused sales to increase considerably. With the passage of time, the modifications also began to be applied with the aim of being able to improve its use and gradually became more productive .

An example of them comes from the hand of August Frehauf who managed to adapt a trailer to his vehicle to be able to tow one of his boats and with this, in 1918 he founded the Frehauf Trailer Company , a company that continues to operate to this day. A type of trailer was also created to transport horses and the design was adapted to be hooked to a Ford vehicle, this type of trailer was known by the name of Trailmobile . Over time, trailers were created that had the ability to move up to four or more vehicles increasing the efficiency of the trailer.

What is a trailer for

Trailers are equipment that is used to increase the storage capacity of a certain vehicle and with it it is possible to transport different types of loads , sometimes including people or animals .


In order for the trailer to function properly, it must first be hooked to the vehicle that will transport it by means of a coupling system which serves to fix it and to establish connections with the vehicle. One of the main points for a good operation is the trailer hitch which must be installed by a professional, this hitch is also known as a tow ball .

It is important to remember that when a trailer is used the vehicle tends to destabilize a bit and in situations where braking is required , the weight multiplies and is transferred forward, for this reason it is important that the trailers have a good braking system . In the same way, it is important to always check the lights of the same to avoid accidents.

In addition, there are several important aspects that must be followed after the trailer has been hooked up, these are mainly the certificate from the workshop and the assembly scheme . With these documents, the person will be able to move with the trailer without problems.


There are currently several types of trailers, among them are the following:

  • Industrial type trailer : it has a platform that is accompanied by two axles and is designed with the aim of being able to transport large amounts of weight.
  • Agricultural trailer : they are created to fulfill a predetermined function. It can only be pulled by an agricultural machine such as a tractor due to its large size and weight.
  • Central axis : they are also known as cargo trailer and are characterized by having a single central axis . In this type of trailer the hitch cannot be moved vertically.
  • For boats : they have a structure that has been designed depending on the measurements of the boat that needs to be mobilized.
  • For homes : they are known by the name of caravans and they are a type of small house that has been adapted to the mobile space and that also have several characteristics of their own.
  • Semi-trailer : in this case, we refer to the trailer that a truck has, they are more commonly known as trailers and are used to transport large amounts of materials .
  • Hitch trailer : characterized by having two axles , one of them must be steering . It also has a towing device that allows vertical movement with respect to the trailer and also transmits a load of less than 100 kilograms to the vehicle.


Trailers are important because they are a means of transportation that can greatly facilitate the transportation of materials . They are fundamental in some types of activities such as agriculture and livestock because it is the means by which animals or crops can be taken from one place to another to market it.
