The outstanding stability of the new Dynapac screed VB510TV-(E) -with optional electrical heating - is achieved by the advanced control system for the hydraulically extendable sub- assemblies, where main screed, torsion housing and telescoping components are interconnected via guide tubes. Telescoping components are individually controlled, the screed width is infinitely variable from 2,55 m to 5,10 m by use of telescopic cylinders. A salient feature of the screed design are the guide tubes, which just extend to 50% of their maximum travel even when the screed is fully extended (double the standard width). This, combined with deeper sole plates, ensures exceptional stability and excellent paving results.
