EC480EL Hydraulic Boom Cylinder 14671536 165mm Bore 1660mm Stroke Aftermarket Excavator Spare Part

This heavy-duty aftermarket hydraulic boom cylinder is precisely manufactured as a direct replacement component for EC480EL large excavators. As the core hydraulic driving component of the front working assembly, it controls the lifting and lowering motion of the boom to undertake heavy digging, bulk material hoisting and large-area land leveling tasks. It is widely used in open-pit mining, quarry excavation, trunk highway construction and large-scale infrastructure construction projects.

All products are produced in strict accordance with original OEM technical specifications, with fully consistent mounting dimensions, pin hole spacing and hydraulic port layout. On-site direct bolt-on installation can be completed without cutting, welding or any secondary modification work.

1. 100% OEM Interchangeable Fitment: All structural dimensions and assembly interfaces fully match the original factory design, seamlessly connected with boom linkages and hydraulic pipelines to ensure stable continuous operation under long-term heavy load conditions.
2. Mine-Grade Reinforced Structure: The cylinder barrel and connecting lugs adopt thickened optimized design, capable of enduring long-term cyclic heavy loads and frequent impact collisions in harsh mining and construction sites, greatly extending the overall service life.
3. Multi-Round Strict Pre-Delivery Inspection: Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, completely eliminating hidden risks of internal and external oil leakage.
4. Outstanding Cost Performance: It achieves the same operational stability and service life as genuine spare parts, effectively reducing repeated procurement costs for repair workshops and spare parts wholesalers.
5. Flexible Global Logistics Solutions: In-stock goods can be dispatched within 3 working days. Air freight meets urgent delivery demands, while sea freight is the most economical option for bulk wholesale orders.
