International ers and workforce receive regular ongoing training. The first estimate has been increasingly con- firmed following the first few months. “So far, it looks as if we have select- ed exactly the right run- ning gear,” says Reiner Moog. He and his team wired up the entire trail- er in order to be able to make statements of this kind. Sensors distribut- ed all around the vehi- cle and the running gear measure the loads with the greatest of precision, and even reg- ister the smallest expansions of the material. “At first, we save the data from all the sensors installed in the vehicle on a data logger that is accommodated under the frame. From there, we can download it using a modem connected to the logger, which means we have a current picture of the loads on the running gear at all times,” explains the test leader. Long suspension travel distances The test team has already collected some important information over the past few months. In India, it is the distortions in the carriageway that impose the greatest loadings on the running gear. It’s the same thing with the motorways. “This results in driving manoeuvres at low speed involving long spring travel amplitudes leading to severe running gear distor- tion, which can be asym- metrical in some cases,” says Moog, commenting on the results of the analysis. Highly dynamic manoeu- vres such as driving over potholes at high speed are relatively rare, on the oth- er hand. Consequently, it is important for mechanical trailer vehicles to have ade- quate suspension compression and rebound travels, adds the spe- cialist. Furthermore, it is particularly important for the bearings on the running gear to be well sealed, because the roads and yards get extremely waterlogged and muddy especially during the mon- soon season. Harinder Yadav still has a considerable distance to cover. It is possible that he will not manage the intended 50,000 kilometres in one year. But even after that, there will still be plenty of time left for rolling along India’s roads with the trailer and its ECO Cargo VB running gear.

The ECO Cargo VB running gear seams ideal for the gravel tracks and muddy yards.
