INFRA-KIT | Bridge & cut-and-cover tunnel construction

To reduce the design and assembly effort in bridge building and cut-and-cover tunnel construction, Hünnebeck developed the modular INFRA-KIT system.

The user-friendly INFRA-KIT system is based on the tried-and-tested load frame prop (up to 210 kN of loading per prop) and main beams with wide-ranging applications.

A match for every challenge

The INFRA-KIT system is suitable for a huge range of standard applications in bridge building and cut-and-cover tunnelling, including temporary bridges, vehicle access ways with large spans and heavy-duty towers for bridge refurbishment projects. Even large-span bridge constructions and tall load-bearing structures can be created by using the standard INFRA-KIT system components which all comply with European safety standards.

The small number of standardised system components including brackets, braces and abutment connectors facilitate tailor-made solutions without expensive specially built parts.

INFRA-KIT at a glance

  • Economic infrastructure construction with few system parts and little planning effort
  • Fast and straightforward assembly due to plug-connecting components and secured centering bar via safety clip
  • Automatic self-alignment of the main beams as well as safe transfer of lateral forces due to the integrated shear pins at beam ends
  • High load capacity due to the load-optimized system parts
  • Maximum working safety by use of standardised walkway brackets and PROTECTO® or EXTRAGUARD™ edge protection
