High test requirements –
Far tougher than normal – long test trials under extreme conditions identify weaknesses and rigorously eliminate them. These conditions perfectly test the reliability and day-to-day suitability of a truck and reveal whether the materials used for flexible mountings, air suspension components or seals are also durable to withstand the most extreme climatic conditions.
More rigorous than usual: customer trials constitute one of the most important tests. After all, nothing exposes weaknesses quite as mercilessly as testing in everyday conditions. Constant technical monitoring of the vehicles and in-depth surveys carried out among drivers and operators give us ample opportunity to take any necessary corrective measures and blend “everyday reality” into the truck’s construction before it goes into production. Any weak points can be eliminated and suggestions incorporated. The end result is a truck for different purposes that is capable of everything we expect of it – and of course, of everything you expect of it, too.
Climate and Adverse Conditions Testing
Accelerated weathering tests: during the dynamic corrosion test, the truck is subjected to extreme climatic conditions in the salt spray chamber and climate chamber for a period of several months. To test the quality of the corrosion protection for the vehicle as a whole, the truck must also successfully complete long test stretches on rough roads, motorways, gravelled and muddy tracks.
Surface Encounter Testing
In the servo-hydraulic test station, uneven road surfaces encountered on motorways, country roads or speed bumps are simulated with outstanding precision. The aim of the tests is to improve the vibration characteristics of axles, frames and detachable parts, thus reducing the dynamics of the components, increasing ride comfort and promoting smooth transport of the cargo.
The engines for our vehicles are required to pass test station endurance trials that equate to over 3.6 million kilometres. This standard is set with the purpose of proving reliability and optimization so that each engine is able to operate in the real world.
The propshaft test station further demonstrates the stresses to which the drive system is subjected to before it is allowed to enter service. Test station trials with up to 58 different combinations of engine speeds, torques and bending angles reflect the usage profile and can thus stress the propshafts to the maximum. To ensure that even the slightest damage or cracking is revealed, the shafts and joints are subsequently subjected to component analysis in the laboratory. This analysis is the only way to confirm that they have passed the endurance test in all respects, and that they are able to meet the demanding requirements of long-distance transport.
