HINGED TURNOUT BEARER: EFFICIENT TRANSPORT OF PRE-ASSEMBLED TURNOUTS
The Hinged Turnout Bearer enables the cost-effective transport of pre-assembled turnouts and large turnout assemblies using standard flat wagons. Turnout sections that exceed transport width limits can be folded into a compact position for transport and returned to their intended position on site.
This solution combines the quality advantages of pre-assembly with significantly simplified logistics.
The pre-assembly of turnouts and large turnout assemblies, meaning the assembly of turnouts in the turnout production plant rather than at the installation site, offers not only economic advantages but, above all, significant quality benefits.
The transport of such pre-assembled turnout assemblies has historically not become widely established due to the limited availability and distribution of specialised transport wagons. To address this challenge, RAILONE worked closely with Deutsche Bahn to develop the Hinged Turnout Bearer, an innovation that received the CNA Innovation Award in 2011.
The Hinged Turnout Bearer makes it possible to fold those turnout sections that exceed the permitted transport width for standard transport (W > 3 m) into a compact position. In this folded state, they can be transported using standard flat wagons and subsequently returned to their operational position at the installation site.
Identical manufacturing and installation process as for non-divided long turnout sleepers
Cost-effectiveness: Reduced transport and installation costs, as well as shorter installation times
Quality: Hinged Turnout Bearers are subject to the same quality standards as non-divided long turnout sleepers
Flexibility:
High availability thanks to straightforward transport on standard freight wagons; divided and foldable Hinged Turnout Bearers with a rigid coupling joint
Folding back, unloading and installation using either a rail-mounted crane or a road-rail excavator
