Heavy-Duty Chain for Liebherr R934/Sany SY485, Forged Steel for Mining & Large-Scale Construction Projects
Built for Liebherr R934 and Sany SY485 excavators, this heavy-duty chain is a workhorse for mining and large-scale construction. Forged from high-grade steel, it undergoes a rigorous quenching and tempering process to achieve maximum strength and toughness, handling loads up to 50 tons. The chain’s links are reinforced at stress points, preventing failure under extreme pressure. It features a sealed lubrication system that keeps out dirt and debris, reducing maintenance intervals. Compatible with oversized buckets and attachments, it’s designed for high-productivity operations. Backed by a 2-year warranty and technical support, this chain ensures continuous operation in critical projects.
