The bow plate on a tandem roller is a structural forming component fitted at the leading or trailing edge of the drum assembly, shaping and guiding the transition between the drum and the machine's frame or scraper zone. It helps protect the drum edges and surrounding structure from impact and debris during compaction passes on asphalt and soil surfaces. When the bow plate becomes worn, cracked, or damaged, it can compromise drum edge protection and affect the roller's ability to deliver an even, consistent compaction pattern.
