Short description

USM Ciflex is made of high-grade mixed-cell PUR foam and is manufactured in different thicknesses and densities, which have precisely determined physical characteristics. Thanks to its highly elastic behaviour, USM Ciflex is eminently suitable for reducing vibrations and structure-borne sound in track bed structures. USM Ciflex’s physical properties are tested by an independent body.
The key advantages which USM Ciflex offers are permanent extreme flexibility, even under high stress loads, its excellent insulation properties and its precisely defined load ranges. USM Ciflex is versatile and can be used in both ballasted track systems and ballastless track or mass-spring systems and for all speeds and types of operation.

Short description

Ciprotec is a PU-bound rubber granulate mat. It is versatile and can be used for all speeds and types of operation, e.g. in ballasted tracks on bridges and tunnel floors to prevent ballast wear or damage to coatings in the interface between ballast and concrete or steel. It may also be used for vibration and structure-borne sound mitigation purposes as part of floating slab track or mass-spring systems.

Ciprotec can be lined with non-woven fabric or geotextile and supplied in different thicknesses or rigidities when required.

Type of bearing

Special bearing for the absorption of shear- and restraint forces in slab track systems. Can be supplied in dimensions adapted to the specific project requirements and in thicknesses of 5, 10, 12.5, 15 and 20 mm. The bearing has a load capacity up to 15 N/mm², depending on the format.

Features

  • Premium quality rubber material
  • Highly elastic and resilient
  • Ageing-resistant
  • Prevents damage to ballastless track
  • Easy installation
  • Reduction in maintenance costs for track system

Type of bearing

Special bearing for securing horizontal track alignment or absorption of horizontal forces in slab track systems. Delivered as stipulated on data sheet; differing project-specific dimensions may be available on request.

Features

  • Sturdy rubber-metal moulded part
  • Weather-resistant stainless steel
  • Rubber bearing made of high-grade chloroprene (CR)
  • Built-in part, light in weight
  • Easy installation
  • Secures track position

Description, application

Mass-spring systems are used to ensure protection against vibrations and structure-borne sound caused by railway traffic. The entire track bed structure is decoupled from its surroundings and the transmission or radiation of intrusive vibrations reduced in the immediate vicinity.

Mass-spring systems with very low natural frequencies provide sufficient protection in special cases. Single bearings made from a specially designed elastomer material are particularly suitable for such applications.

These reinforced elastomeric bearings comprise high-grade synthetic rubber with a chloroprene rubber (CR) content of more than 60%. They each feature a 2 mm thick plate of weathering steel vulcanised into the upper and lower sections with a form fit and non-positive connection to improve absorption of transverse splitting forces.
