Benma is a Chinese manufacturer of compact road rollers and light compaction equipment, often marketed internationally under the brand name Storike. Based in Jining City, Shandong Province—a region known for construction machinery clusters—Benma has positioned itself as a rising player in the global light equipment market. While not as widely recognized as giants like Sany, Shantui, or XCMG, Benma’s Storike-branded rollers have gained traction in emerging markets and niche applications.
The company specializes in small-scale rollers ranging from 0.3 to 2 tons, targeting municipal maintenance, landscaping, and small contractor fleets. Their compact rollers are often used for asphalt patching, sidewalk compaction, and trench backfill.
