High Quality Excavator Arm Boom Assembly Heavy Duty Construction Machinery Spare Parts
Product Description
Our premium excavator arms and booms are engineered for maximum performance and durability across demanding construction applications. They are fabricated from high-strength steel alloys—including Q345B and Q460—as well as advanced wear-resistant materials like Hardox and Weldox, which are widely recognized for enhancing structural strength and abrasion resistance in earthmoving components .
Each unit undergoes rigorous quality control, including ultrasonic testing and magnetic particle inspection to detect micro-cracks and ensure weld integrity, alongside precision dimensional checks using CNC equipment . These processes guarantee compatibility with a wide range of global excavator brands and reliable performance under heavy cyclic loads.
We offer multiple configurations to suit varied operational needs: standard reach for general excavation, long-reach and super long-reach booms for extended digging depth or height, and heavy-duty demolition arms reinforced with extra plating to endure high-impact forces . These are not just replacements—they’re performance-enhancing upgrades that restore or expand machine capability.
From material selection to final inspection, our manufacturing adheres to international standards, ensuring every arm and boom delivers long service life, reduced downtime, and a strong return on investment. Backed by global logistics and technical support, our components keep your projects moving—safely, efficiently, and on schedule.
