Why the EX200 H-Link Matters
The H-link, also called a boom-arm connector or center bracket, is a structural pivot that links the boom and arm of your Hitachi EX200 excavator. During digging, trenching, and lifting, this part balances the rotational movement and absorbs repeated shocks from the hydraulic system and bucket action. In machines like the EX200—widely used for road building, foundation work, and utility trenching—the H-link endures cyclic loads, lateral forces, and torsional vibration every hour of operation. A poorly made or worn-out H-link can cause improper articulation, premature wear of the boom cylinder pins, or even misalignment that affects digging force and bucket control.
So replacing with a properly engineered, OEM-compatible H-link is critical to restoring operational precision and extending the service life of surrounding components.
Manufacturing Workflow & Quality Control
The production process follows strict standards to deliver OEM-level reliability:
After selecting high-grade steel, the H-link is hot forged to create a dense, impact-resistant shape. It is then precisely machined on all bearing surfaces, especially at the pin joints, to maintain alignment. During finishing, it receives corrosion protection before undergoing final inspection.
Quality checks include dimensional verification with CMM, pin bore gauge testing, and ultrasonic flaw detection for any internal cracks. Every H-link is batch-tracked and fully inspected before packaging.
Pre-Machining Storage
Before final processing, each H-link is carefully stored after forging and initial shaping. You can see the robust raw units neatly stacked and ready for CNC machining and heat treatment — a testament to our in-house forging capability and batch processing control.
Export-Ready Packaging
Once machining, inspection, and anti-rust treatment are complete, the finished H-links are securely packed in palletized crates or wooden boxes, ensuring safe transport over long distances. All packages are labeled for easy identification and can be customized with your logo or barcode if required.
Fitment Information & OEM References
This H-link fits the following Hitachi models:
- EX200 / EX200-1 / EX200-2 / EX200-3 / EX200-5
- EX200LC, and other variants with matching boom-arm geometry

Designed for Everyday Excavation Challenges
Hitachi EX200 excavators are widely known for versatility and are often used across general construction, forestry clearing, drainage ditching, and rural infrastructure. These scenarios expose the H-link to varied loads, from bucket impact to cylinder thrust, and terrain-induced twisting.
Our H-link is designed not just to withstand these challenges, but to actively support smoother movement and precise force transfer—reducing stress on adjacent parts like the bucket link and arm base. It offers consistent performance whether you're operating in dry plains, dense clay, or light demolition.
Maintenance Tips for Longevity
To protect your new H-link and the excavator's boom assembly:
- Grease pin connections regularly, especially in dusty or wet conditions
- Inspect pin bores every 800–1,000 hours for signs of elongation or cracks
- Check for misalignment if you notice unusual bucket movement or drift
- Always replace worn pins and bushings together to maintain structural balance
- Proper maintenance keeps the H-link performing effectively and prevents costly downtime.
