Link-Belt® Catenary Bar Screen

Rugged and reliable, Link-Belt® Catenary Bar Screens are commonly used in unattended applications such as CSO control facilities, where the debris loads can be heavy and varied. Sprockets, bearings and shafts are located above the maximum water level, facilitating ease of maintenance and the potential for damage and corrosion. The rakes bear against the face of the bars by the catenary action of the chain. The chains are not guided which means that the rakes can ride over an obstacle without jamming or overloading.


  • Maintenance easily completed at the operating level

  • Simple, trouble-free design 
  • Robust construction available in carbon steel and stainless steel 
  • Versatile operation under varying flow and load conditions

  • Bar rack incline from 60o to 75o  


  • CSO control facilities
