Product information

The benefits at a glance

Great versatility

  • Variety of suspension arrangements, combined suspension fitting
  • Light, compact design
  • Universal suspension can be fitted on profile sections and C rails
  • Snap-on connection – e.g. for perforated sheet or drilled girder web
  • Single suspension for variable centre distance
  • Suspension distances up to 3 m
  • Straight end sections can be cut by hand – no need for additional preparation of joints (cut-outs, drilling, etc.)
  • Isolating sections, powerfeeds and transfer sections can be quickly fitted and changed on site

High safety and reliability

  • Safety busbar line with IP 23 protection against accidental contact for horizontal installation
  • Reliable power transmission by current collector pantographs
  • High electrical safety due to large spacing between conductors and variable centre distance for single suspension
  • Expansion joints between all conductor sections absorb differences in length caused by temperature variation
  • Corrosion resistance

Convenient assembly and maintenance

  • Simple installation thanks to prepared assemblies
  • Bolted suspension, compact dimensions
  • Easy maintenance as conductors and current collectors are easily visible
  • Rapid disassembly of conductors thanks to patented quick-release joint connection
