The approximately 13,35km long Wienerwald Tunnel comprises a significant part of this newly built section and connects the western edge of Vienna (Hadersdorf-Weidlingau) with Tullnerfeld.


The opening of the complete Wienerwald Tunnel as part of the newly built section between Vienna and St. Pölten is planned for 2012.

U slučaju abrazivnog i korozivnog korišćenja, u nekim komponentama može doći do prirodnog habanja. U pogledu gornje primene do habanja može doći pre svega kod rotora, agitatora, usisne ploče, rukavca vratila, uljanog prstena, mehaničke zaptivke, kućišta pumpe, sita, kućišta motora i ispusne spojnice. Radni vek ovih delova može znatno da varira zavisno od radnih uslova i može biti kraći od garantnog perioda.
U tom smislu obratite pažnju na naše opšte uslove korišćenja koje vam takođe na zahtev šaljemo poštom.
