Normal operating conditions tests

On-road

In order to definitively determine the functionality of the Nord-Lock wheel nut, it was tested on real life vehicles in real life service. During the first 100 km of driving and retightening a safety car followed the truck. In the on-road test the LCW truck tested at RDW in Lelystad was used for transport services for 7000 km without detecting any rotation of the wheel nuts. The vehicle was driven on an even mix of highway and urban roads.



Off-road

The off road test was performed involving a military vehicle in desert environment. The trailer was fitted with the Nord-Lock wheel nut on one side of the axles and regular wheel nuts on the other. The vehicle was driven fully loaded at maximum speed during a service period of three months. None of the Nord-Lock wheel nuts had rotated.
