Keltec’s Travelling Bridges remove grit and grease from rectangular tanks. There is one surface scraper and one bottom scraper installed underneath the bridge.
The tank has two main parts, one to settle grit and the other to collect grease. The bridge travels back and forth along the tank, traveling one way, it pushers the settled grit into the grit collection hopper using the bottom scraper. Running in the opposite direction it collects scum and floating particles using the surface scraper.
These bridges can be supplied in both galvanized and stainless steel.
