HeavySim - At a glance

Developed by insiders

HeavyGoods.net is a spin-off of Fraunhofer IVI, where innovative steer-by-wire systems for complex multi-axles steered vehicles have been designed and implemented since 2004.

Using their great know-how in vehicle simulation and maneuver planning Fraunhofer developed the automatic maneuver planning algorithm TruckTrix for multi-axle steered vehicles, which is used in HeavySim. HeavyGoods.net provides this and other innovative technologies to vehicle manufacturers and transport companies worldwide.

Tools for designing vehicles

Steering function designer and circular driving test simulation

  • Simulation of §70 maneuvers including examination of ring area width and off-tracking dimension
  • Visualization of steering rays
  • Instant-view of bending and steering angles
  • Tuning of the characteristic curves for forced steered semi-trailers
  • Analysis of steering angles for lazy-steered vehicles
  • Telescope capable vehicles (width and length) supported
  • CSV export of calculation results, e. g. for Microsoft Excel

Easy input of vehicle data

  • Convenient templates for many vehicle types: Add tractors, semi-trailers trailers and module combinations to your catalog with just a few clicks
  • Live visualization of vehicles - both top and side views
  • Easy input of axle configurations and steering functions
  • Supports telescope capable vehicles (width and length telescoping)
  • Configure various designs such as platform, low profile or drop deck trailers

November 2018 - HeavyGoods.net simulates transport of christmas tree

How to transport a 22 metres long christmas tree to the world famous Striezelmarkt Dresden? No problem with HeavyGoods.net. Watch the time-lapse video of the transport!

October 2018 - Cargos Reloaded

Extraordinary cargos make special transports so special. The new cargo editor now allows to enter and simulate cargos with any outline. This makes the simulation even more realistic. We already provided a windmill blade as an example.

October 2018 - More languages available

HeavyGoods.net now already is available in four languages. You can choose from German, English, Spanish and Italian.

September 2018 - New vehicle types

HeavyGoods.net continuously evolves. Thanks to intelligent Fraunhofer TruckTrix technology even more vehicles can be simulated with HeavySim: Trucks with fifth-wheel coupling or trailer coupling, platform trailers, low loaders, lowbeds, module combinations with or without bridge, trailers and modular trailers.

September 2018 - Invitation to the IAA

Heading towards Industry 4.0 with HeavyGoods.net: Experience innovative software with intuitive usability. Simulate large-capacaity and abnormal load transports or construct new vehicles. HeavyGoods.net works with proven Fraunhofer technology. This cooperation also manifests at the IAA with a combined booth.

We heartily invite you to the IAA Commercial Vehicles 2018, September 20-27 2018. Experience the future, in Hall 16, Booth E36. We look forward to you.

July 2018 - CAD support

From now on you can upload your own CAD drawings to HeavySim and create tractrix simulations on them. No CAD software knowledge needed.

June 2018 - Test HeavySim for free

You want to know whether HeavySim fits your needs? Test the simulation software for three months free of charge. Until 31.08.2018 you can .*

We prepared your account with example transports, vehicles and a quick start video so that you are ready to run your passability checks right from your office desk.

May 2018 - HeavySim available worldwide

Transport companies from all over the world can now use HeavySim for their heavy load transport simulations. The print view for simulations and tractrix curves completes the service.

March 2018 - HeavySim has landed!

Transport companies all over the European Union can now . Please contact our support team if you want to use HeavySim in a Non-EU country.

November 2017 - Cooperation with Kahl

We welcome the international company for transport logistics KAHL Schwerlast GmbH as a launching customer of the HeavyGoods.net platform.

December 2017 - Felbermayr, KVS and Universal Transport

With Felbermayr and UTM Universal Transport we welcome two more renowned transport companies in addition to KAHL on the HeavyGoods.net platform. Additionally a smaller, but in Dresden, Germany, well-known transport company named KVS joins the launching phase of HeavyGoods.net.
This helps us to reach an important objective: Providing innovative tools for planning heavy goods transports for transport companies of any size.

November 2017 - Passability checks

Our customers from the heavy goods transport industry order HeavyGoods.net analyses in order to check for narrow spaces when planning new transport projects. For details check our example report.

November 2017 - Goldhofer and Scheuerle

The international well-known vehicle manufacturers Goldhofer und Scheuerle already use our HeavyEngineer Software. HeavyEngineer simplifies the construction of new vehicles. Existing and new vehicles can be released to the HeavyGoods.net platform so that transport companies can use them for planning and simulating transports.

October 2017 - Retrospect "Schwerlasttage"

We got lots of positive feedback for our live presentation of HeavyGoods.net at the trade fair "Schwerlasttage 2017" in Hohenroda. The audience was excited by the pioneering developments of HeavyGoods.net and innovations of the cooperating Fraunhofer research centre. Lots of interested transport entrepreneurs and vehicle manufacturers visited the HeavyGoods.net's stand to experience the software suite themselves.

February 2017 – Pilot operation started

First apps of HeavyGoods.net are now being tested by end customers.

IAA Nutzfahrzeuge 2016

HeavyGoods.net presented its newest innovations at the international trade fair IAA Nutzfahrzeuge in Hannover. From 09-22-2016 to 09-29-2016 the international audience joined presentations of the rich feature set of HeavyGoods.net.
