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, permissable 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 permissable axle and boogie loads, bridge rules, total weights, turning and more.

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 calculation 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 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 range 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 and load-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. These diagrams are available for both trucks and truck and trailer combinations.

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.
