Link-Belt - Model GB -Catenary Style Bar Screens
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.
The Cog Rake Bar Screen can be designed with a complete non-lube system, which includes the cog wheel, pin rack and guide rollers. With this system maintenance is greatly reduced. The screen can be designed for new construction or can be designed to fit an existing channel. Each screen is fully assembled and tested before shipping and is shipped assembled unless shipping limitation or special installation requirements dictate otherwise.
