Verona Bridge – 14.40 m

The Verona Bridge is a 14.40-meter-long temporary bridge used for track reinforcement. It consists of two main beams 1060 mm high into which the metal beams (HEM 180) are inserted, and it is braced by 5 transverse diaphragms made of adjustable profiles.

The Verona Bridge is a 14.40-meter-long temporary bridge used for track reinforcement. It consists of two main beams 1060 mm high into which the metal beams (HEM 180) are inserted, and it is braced by 5 transverse diaphragms made of adjustable profiles. The same assembly scheme and metal sleepers used in other Petrucco systems (such as the Verona System with transverse beams and the 7.80 ml Verona Bridges) are used in this bridge, allowing it to be assembled in less than 4 hours.

Here are some technical details about the Verona Bridge:
• Pins and bolts are used to create all connections and constraints.
• The foundations are reinforced with rubber bearings.
• The maximum distance allowed between straight tracks in the application of two Verona bridges of 14.40 m is 3.55 m
• The maximum curve allowed is a 500.00 ml radius
• The maximum train transit speed is 80 km/h

The Verona Bridge is protected by an international patent owned by Petrucco.

 

Verona System

The Verona System represents the last evolution of the temporary bridges to be installed on the tracks. It is covered by an international patent that is property of the Petrucco Group. It is a modular bridge that can be installed in a single span up to 14,40 m or on longer spans (applications on more than 41 m have been done, but there’s no theoretical limit) if used with transverse beams. Both setups are allowed to let the trains flow up to 80 km/h during the whole period it is installed, for both passenger and freight traffic.
The Petrucco Group has also developed this technology to be installed on railway switches in order to keep them active.

The Verona System is developed in accordance with the Eurocodes and the Italian Railway standards and it has been checked also to be in full accordance with the American and Canadian Standards.

The Petrucco Group is always at the client’s disposal to develop custom solutions for their particular needs and constraints.

 

C60 Temporary Bridge

The C60 bridge is a temporary railway bridge developed to sustain the tracks and allow train traffic during jacking operations underneath. It is a single span bridge that is grounded on dedicated foundations that are calculated for each single application.
It has been used in Spain by the National Railway authority (ADIF) since 2006 and its application is compatible with different gauges, both international and Spanish.

 

Garutti System

Used since 1978, the Garutti System is the first system of railway track reinforcement on transverse beams to be used in Europe. It is composed by clamps (Garutti) and rail bundles.

The applications are suitable for both, rail tracks and switches with all international gauges. Usually the maximum speed allowed is 30 km/h, but Petrucco has developed a modified system that has been accepted at 60 km/h for the Spanish High-Speed railway.
