New Goldhofer technology tested

Specialized trailer manufacturer Goldhofer will begin production of the new STZ-MPA semi-trailer generation following successful tests of its independent suspension system.

The independent suspension system, called MPA Axle Technology, comprises one wheel carrier, strut and suspension arm, a company spokesperson said. It has undergone tests for function and safety.

Volker Schmidt, chief design engineer at Goldhofer, said, “We simulated vehicle performance with MPA axle technology on a hydropulse test rig and all the components passed the tests with flying colours, for example, for the maximum load cases and alternating load cycles. We are highly satisfied with the results.”

The test rigs at Goldhofer’s systems partner BPW were used to simulate the performance of the wheel suspension under continuous high loads, a company spokesperson added.

“We wanted to know exactly what happens to the individual components, and when and how they react to which load,” Schmidt explained. “To see how the suspension must work, for example, we have fitted the vehicle with various sensors and are using the latest software for data capture.”

The new STZ-MPA semi-trailer has a 60 degree steering angle, 315 mm suspension stroke and a 780 mm minimum loading height.

The first shipments of the new trailer are scheduled before the end of 2013.
