Catenary Chain Rake

This mechanical Catenary Bar Screen replicates the same principles as a front-cleaned Chain Rake. The chains and rakes are specially engineered to hang free inside the water channel and employ their own weight to engage the screen bars at the channel bottom and effectively remove the debris from the channel before it can damage pumps and other downstream equipment.

The Model SYBS bar screen’s unique, free hanging, design eliminates submerged water parts like shafts, bearings and sprockets and is virtually "jam-proof". This feature makes it an ideal Chain Rake Bar Screen for applications when equipment sits idle for long periods and instant start-up operation is required. It is a highly efficient Chain Rake for high water-flow with variable debris removal demands and solidly designed and manufactured to deliver long service life.

The Catenary Screen comes equipped with a bar rack, beaching plate, multiple rakes, rake wiper, drive chain, upper sprockets, chain return guide rail, shafting, bearings, drive unit and simple control panel. Optional features include trapezoidal bars and various bar space openings.
