2. Know what weight will you transport


The basic reason why you will need a trailer to take up a certain load is usually because of its weight. On its part, the modular trailer provides you with a solution to the following benefits as discussed below:

  • It is suitable equipment for the transportation of heavy cargo. Ideally, it can take up to thousands tons of weight. The capacity take per axle is up to 45 tons.
  • The steering angle can easily be controlled hence enhancing maneuverability. This is a very useful aspect for heavy cargo transportation. You want to be sure that you can easily handle your cargo with a lot of flexibility.
  • Most importantly, it can be driven by a tractor truck hence making the modular trailer economical to use
  • Modular trailers will provide you with a range of applications. There is a good axle spacing choice for use in public roads offering you high bending moment even for off-road application
  • Different combinations can be applied along with other technical features such as axle load and the use of twin tires to give you great capabilities.
  • Off-road applications for heavy cargo us also possible due to an optimized lateral stability for the modular trailer. You can comfortably use it for mining activities and so on.


3. Meet Quality Compliance


Quality is always the most important thing, especially in heavy-cargo transportation. Look at the rationale behind the design and how it will enhance your operations.

The use of professional technology can make the working platform of a modular trailer more stable. Stability is a very important factor with cargo transportation.

A good quality modular trailer should be stable enough to promote safe operations. In that case, it is very important to keep horizontal in order to keep the cargo in balance and from falling off.

Serious buyers would want to get the technical drawings along with other details of the trailer to establish the quality.

Therefore, get as much information as you can to assess the quality prior to buying any trailer. Look at the material used for its construction and the quality of welds done on the structure.

These will go a long way into defining the performance and lifespan of your modular trailer.

4. Choose right Types of Modular Trailer


All features included in the design of a modular trailer have a certain need to meet. Therefore, seek to understand the difference in the installed features prior to purchase.

One of the defining features of a modular trailer is the type of bearings installed. There are two types of modular trailer categorized based on bearing: Pivot Bearing and Ball Bearing Race Ring.


  • Pivot Bearing Type – this is commonly used for light weight capacity modular unit. 23T-25T. Be ready with information on your weight specifications and settle for this if the tonnage is within the given range. There is no point of getting a bigger one while this can suffice. Despite the light weight operations, this type can also offer you with a wide range of applications. It can be used for construction site operations and in public roads as well. This is usually for extremely low dead weight with features of big tires that makes it suitable for off-road use. It also has technical features offering good bending moment that enhances your operations on the different locations. 
  • Ball Bearing Race Ring – this is commonly used for heavy load modular unit 30-45T. Don’t buy a modular trailer type that cannot handle your weight needs. If this is the weight range of your cargo, don’t force it on the pivot bearing type. Instead, go for the ball bearing race ring. With this type, lifting your heavy loads becomes possible. You can use it in public roads and operations within your plant. It gives you an optimum ratio for the payload versus the axle load. Another important feature is the torsion-resistant frame that comes with a closed loading platform facilitating the carrying of concentrated loads as well as heavy-duty cargo in the drop deck.

Other than just looking at the weight capabilities of these two types of modular trailers, you can also choose whether to install the gooseneck or not.

A gooseneck design helps you to save space and makes use of lighter units via a perfectly hinged frame assembly. Your seemingly heavy cargo becomes a light operation through this feature.

It offers you the ability to handled complex situations on different terrain especially on off-road applications.

At times, handling heavy cargo becomes somewhat complicated.

You can choose between combination gooseneck modular trailer and the universal gooseneck modular trailer to get your desired performance. See figure 1 below

5. Choose Right Combination


Don’t just note the weight of your cargo. In addition, establish your cargo’s dimension. Remember that you can choose the right combination for a modular trailer according to the dimension.

  • Make considerations of how many rows to choose. In your selection, you may find out that some cargo may be too wide. In that case, you cannot settle for 2 rows because they will not be enough. See figure 2 below

  • If the cargo is very long, you need to use some special accessories. Therefore, make arrangements to get the same also. It is important to go for external components that will make your modular trailer more useful than if it was all alone. If it is really too long, such as a girder, you will have to get a turntable. See figure 3 Don’t buy a modular trailer without the required accessories to help in handling your cargo lest it be rendered useless. Enquire from the experts and get useful information to help you make the right choice of accessories for your modular trailer.

  • If your cargo is too high, you will need a low-profile drop deck and a vessel bridge. See figure 5 below. This is an optimum combination of the required bending moment of handling such a cargo and loading cargo of such a height. There is a range of applications for this kind of combination. You can use it for public roads applications and again for operations within your plant. Even if your cargo is very high, this combination provides you with a low loading height. Still, it has an optimum ratio of payload to the axle load and is designed to take up concentrated loads as well as heavy-duty loads while in the drop deck. The bending moment is usually high, something that enhances capability of the equipment.

There are those designed for minimum loading height for maximum requirements and the same includes a range of applications for public roads.

There is room for alternative width aimed at giving you excellent maneuverability. You can also achieve mechanical width adjustments through the use of spacers.

Still these are optimized for high loads as well with an optimum payload to axle load ratio. Most importantly, it will offer you with the lowest loading height to make the operations easy and manageable.
