Type Approval Services

Modern commercial vehicles must comply with many EC Directives that form the basis of the vehicle Type Approval.  Altering or converting a chassis will impact on this approval and the most critical are the braking directives.  Granning pioneered the installation of additional axles to trailers and trucks/tractors in the early 1980’s. Since then we have developed considerable expertise, and a vast library of conversion Type Approvals in order to satisfy UK National Type Approval requirements ensuring that the necessary regulations are adhered to and that the completed vehicle will be suitable for the intended purpose

We have some of the very latest technology for recording vehicle-braking performance and have written our own brake performance analysis computer software in order to enable us to remain at the very forefront in this area, when re-approval of the braking system is required as a result of a conversion.
