Dymax Rock and Mass Excavation Buckets are engineered for demanding rock and mining applications where durability and uptime matter most. Built from abrasion-resistant steel and configurable with heavy-duty edges and wear packages, these buckets are designed to match the machine, material, and production requirements of large-scale excavation work.
“We have a mine customer in the far reaches of Siberia who prefers Dymax Buckets over others, because they outperform and outlast other brands. On top of this, Dymax personnel were the first bucket manufacturer to visit us and our applications. They are great folks to work with.”
