Static strength measurements in the factory: PJM carries out tests using a mobile pressure frame

The key data of Plas- ser & Theurer‘s 09-3X track tamping machine are impressive: 80 tonnes net weight, 35 m length, 8 axles, and 3-sleeper tamping units ensure powerful and efficient working.

The static strength tests according to EN 12663-1 for the Plasser & Theurer 09-3X track tamping express were carried out at the factory in Linz.

To de- termine the stresses and deformations of the vehicle frame, PJM carried out pressure frame tests according to EN 12􏰀􏰀3-1. The strength tests were performed at the Linz factory of the technology leader and manufacturer of track maintenance machines. This has clear ad- vantages for the machine manufacturer: the entire on-site infrastructure is used and any adaptations to the object can be coordinated with the design engineers and immediately implemented. Using PJM’s mobile pressure frame allows the tests to be carried out direct- ly in the factory. Thanks to its modular design, the pressure frame is suitable for every type of vehicle. It has proven its effectiveness in static tests in numerous projects.

„Testing with the mobile pressure frame at the customer‘s site provides full transparency for the calculation engineers with regard to test pro- cedure. It also greatly facilitates validating the calculation models. This approach ensures the least possible amount of time is spent in pro- jects,“ explains Martin Joch, CEO of PJM. „PJM handled the measurements very efficiently and professionally. We greatly benefitted from the fact that they were carried out on our premises in Linz,“ confirms Andreas Pumberger, Head of Railway Testing Lab, Plasser & Theurer.

As an accredited testing laboratory according to ISO/IEC 17025, PJM carries out measurements, tests, and analyses for the approval of rail vehicles and track maintenance machines.

PJM as a testing laboratory
As an ISO/IEC 17025 accredited testing labora- tory, PJM performs measurements, tests, and analyses in the field of vehicle approval. PJM was the first privately accredited testing labo- ratory in Austria. It carries out approval tests in the areas of driving technology, strength, braking, aerodynamics, and acoustics for international customers worldwide, among them the suburban rail in Berlin, Chicago, and Riyadh, the metros in Barcelona and Glasgow, the London Underground or the Westbahn (Western Railway in Austria).
