Software for building and constructing trucks and trailers.

In TrailerWIN you will find a large database with trucks, cranes and equipment and you can easily build up complete truck and trailer combinations with equipment while getting real-time axle load calculations. The program calculates weights and axle loads, dimensions, permissible loads and allows you to make turning calculations. TrailerWIN also checks the combination you've built for the most important regulations and gives warnings regarding weights and dimensioning, such as permissible axle and boogie loads, bridge rules, total weights, turning and more.

Calculating D- and V-values for trailer couplings due to R55 regulation

TrailerWIN automatically calculate D- and V-values for trailer couplings and fifth wheel couplings so you will get this automatically in the program.

Calculating lift axle situations

In TrailerWIN you can also calculate with axles lifted on trucks and trailers. With axles lifted you will get weight calculation and also turning calculations to check for turning regulations in both situations. Lifted axles are defined directly in the program by the user.

Calculating center of gravity in horisontal and vertical directions

In TrailerWIN you get horisontal CoG position calculated automatically in the program, you are also able to calculate vertical CoG by giving the CoG point for chasis, body, load and equipments. The function gives you a calculated CoG for both unloaded and loaded situation.

Exporting calculation data to other program modules

TrailerWIN is designed to work together with other program modules developed by Trailer Consultation. You can easily move for example to CraneWIN to make crane stability calculations or to CornerWIN to do turning simulations without having to build up the truck with the crane from scratch. All data from the TrailerWIN calcu

lation will automatically be transferred into CraneWIN/CornerWIN for further calculations.

Printing and Exporting calculation data to other programs

By using the clipboard you can easily move the drawing from TrailerWIN to some other software, a feature that can be useful for example when making quotations etc. You also have the possibility to save the drawing, with or without measures and weights to an image-file or to export it to a CAD-program with the DXF-file export function. The data-page can be stored into a text-file.

TrailerWIN also allows you to print out calculations and for you to add a text-page to your calculation. This function is a good way to keep data on different cases/calculations in one program.

Trailers and B-double combinations

In TrailerWIN You can define most type of trailers; 1-4 axle semitrailers, 2-6 axle trailers and 1-3 axle center axle trailers with both rigid and steer axles in many different variations. The database also contains a large amount of standard trailers. TrailerWIN allows you to build up truck and trailer combinations with 1-2 trailers, B-double combinations and more. TrailerWIN also gives you the possibility to make turning calculations with these combinations.

By combining TrailerWIN with the CornerWIN program module, You can benefit of more advanced turning calculations and simulations.
All data from the TrailerWIN calculation you've made, will automatically be transferred to CornerWIN and there is no need to re-build the combination. Read more about CornerWIN here.

Truck data and drawings

In TrailerWIN You will find technical data on most truck brands on the market. You can easily select the model from a list and get technical data such as measures and weights for different wheelbases on all truck models. The database is constantly growing, since we continuosly update our database with new models to keep the model ranges up-to-date. The TrailerWIN database also includes a number of cab-models that can easily be

 changed during a work-session.

Truck bodies

You can design all type of bodies directly in TrailerWIN and you can choose among different body types ranging from standard box-bodies, curtain-siders, wood-transport bodies to sea-containers and car-transport bodies. With TrailerWIN You will also get a large amount of standard bodies as detailed drawings, these include garbage bodies, concrete mixers etc. You also have the possibility to import your own DXF-drawings to use as truck bodies in TrailerWIN calculations.


The TrailerWIN database includes most of the cranes available on the market (Hiab, HMF, PM, Effer, Fassi, Palfinger, Amco-Veba, Copma, Erkin etc). The crane data includes both drawings and technical specifications. By combining TrailerWIN with the CraneWIN program module, You can launch CraneWIN directly from TrailerWIN and the calculation data from TrailerWIN will automatically be transferred to CraneWIN for crane stability calculations. Read more about CraneWIN here.

Other equipment

TrailerWIN includes most types of accessories used on trucks, such as skiploaders and hooklifts, tailgate lifters, truck mounted forklifts, tippers, tool-boxes, air- and fuel-tanks, bumpers, cab-extensions etc.

Loads and load pictures

To easily build up a realistic load situation, You will find a rang

e of different loads in the TrailerWIN database. These loads can also be split into several part-loads. The software comes with a large range of load-pictures such as cars, boats, tractors, timber-tractors, containers, etc. which can be selected from the load-menu. When adding these loads You can specify the exact weight and COG to get a realistic load calculation for the truck with the chosen load. With the TrailerWIN measuring and drawing tool You can easily check and draw additional measures directly into the picture. 

Turning calculations & loading and deloading diagrams

You can easily check the static turning calculation directly in TrailerWIN. From the static turning picture You can see the theoretical minimum turning radius in a 12500mm EU-circle. You can also define the steering geometry of the truck by giving max turning angles for the inner and outer wheels as well as front axle track.

In TrailerWIN You can see the load- and deloading diagrams that show how the load will affect the axle loads. TrailerWIN also offers a function that is useful for bodies that are loaded from the rear-end (i.e. garbage bodies). The diagram shows you how the front-axle weight will change during loading/deloading and is useful for determine what capacity of axle weights the customer needs for specific use. These diagrams are available for both trucks and truck and trailers.

Versions of TrailerWIN

TrailerWIN is available as both an EU-version with kg:s and mm:s and an US-version with Lbs and Inches. 
In the US-version You can also activate the "US-measurement"-system that shows the measurements as they are used in the US-market area.
US-version has a database with mainly US-trucks only but equipment databases are same for both versions. In EU-version there are also some of the US-models trucks available.

Rules and Regulations

TrailerWIN includes the most important rules and regulations and You can easily choose different regulations from the menu. The program comes with 2 regulations on delivery, additional regulations can be ordered for a small additional fee if needed. Note that for certain countries you will need additionally CornerWIN software in order to perform turning calculation as simulation (for example Finland). Please contact us if you have questions about the regulations in your TrailerWIN license.
