EC480EL Hydraulic Boom Cylinder for Excavator | PN:14671536 | Premium Aftermarket Replacement
1. Basic Product Info
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.

3. Product Advantages
- 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.
- 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.
- 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.
- 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.
- 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.

5. FAQ
Q1: Can this boom cylinder fit EC480D or EC480E excavator models?
A: No. Different excavator models are equipped with exclusive part numbers and unique structural dimensions, which are not interchangeable. Please confirm your complete excavator model code before placing orders.
Q2: Does the standard package include the matched seal repair kit?
A: The seal repair kit is not included in standard delivery. You can purchase the dedicated supporting seal kit separately, and we will offer a competitive combined order quotation.
Q3: What packaging is adopted for long-distance overseas sea transportation?
A: Anti-rust oil is injected into the cylinder inner cavity, anti-rust grease is evenly coated on the piston rod surface; the whole cylinder is wrapped with waterproof PE film and packed in reinforced export plywood cases to avoid collision and moisture damage during long ocean transit.
Q4: Are there tiered volume discounts when purchasing a full set of boom + arm + bucket cylinders?
A: Yes. Complete cylinder set orders enjoy graded preferential pricing. Consolidated container shipment service is also available to lower customers' total logistics expenses.
Q5: What after-sales technical support can be provided if oil leakage occurs within the warranty period?
A: Please provide clear photos of the leakage position and the excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance in a timely manner.
