Important results from the project
The purpose of the project was to design and manufacture a well-functioning, robust and cost-effective HILA demonstrator for transfer of banks and stakes. The goal was to reduce fuel consumption for unloaded timber vehicles with sliding tables, facilitate conversion between different numbers of stacks and replace heavy sliding table cylinder. A fixed demonstrator rig has been built on a timber trailer. A shorter test program has been successfully completed with lighter loads that show that bundling can be performed without drawer effects, completely according to the project goals.
Expected long term effects
Results in the project´s functionality test have turned out according to expectations. Some restrictions in comparison with the original plan have had to be made, such as missing tests in the field. In a parallel Skogforsk project, a driving test with wind-repellent skirts and contracted banks and stakes on an unloaded timber trailer has been carried out. Fuel consumption can decrease by 1-2 percent on average. Bundled banks and stakes have significantly greater savings potential on timber trains running at 120 km / h, which would be interesting to study in future projects project.
Approach and implementation
The project was divided into work packages: 1. Concept selection, 2. Detailed design, 3. Construction and testing in a lab., 4. Test program on a timber truck, and 5. Testing in actual operation. Work packages 1-3 have been carried out according to plan and work packages 4-5 have been partly carried out in the form of driving tests with bundled banks in the parallel Skogforsk project ETT-aero2. Project meetings with participants from industry and academia have been conducted. They have influenced the design of the demonstrator and they have generated new solutions to logistics problems.
