Excavator Chain for Doosan DX300/Case CX300, High-Tensile Steel Links, Anti-Corrosion for Marine & Coastal Projects
This excavator chain is designed for Doosan DX300 and Case CX300 models, with enhanced anti-corrosion properties perfect for marine construction, coastal infrastructure, and dredging operations. Made from high-tensile steel with a duplex coating (zinc + epoxy), it resists saltwater and humidity, preventing rust and degradation. The chain’s pins are coated with molybdenum disulfide for self-lubrication, reducing maintenance needs in remote locations. It’s engineered to handle the weight of large buckets and continuous movement, ensuring stability on soft or uneven seabeds. With a 15-month warranty and custom length options, this chain is a reliable choice for waterfront projects.
