Heavy-Duty H-Link for Doosan DH80 Excavators
The H-link (also known as the H-type arm bracket) plays a vital role in your DH80’s front-end linkage system. It connects the boom and arm, allowing smooth articulation while distributing hydraulic force during lifting, digging, and loading operations. A high-quality H-link enhances equipment stability, reduces wear on connected joints, and extends the service life of bushings, pins, and cylinders.
This H-link is especially suited for high-frequency tasks such as:
- Urban infrastructure construction
- Cable trenching and pipe laying
- Foundation excavation in confined work zones
- Compact earthmoving operations with heavy daily cycling
Material & Manufacturing: Forged Strength for Endurance
Our DH80 H-links are forged from equivalent high-strength alloy steel, known for its excellent mechanical properties and weldability. The manufacturing process includes:
- Material: Made from premium-grade Q345B structural steel, offering high yield strength and excellent resistance to fatigue and impact.
- Forging Process: The bracket is hot-forged to achieve a dense internal grain structure, eliminating weak spots or casting voids.
- Machining Accuracy: CNC finishing ensures precise dimensional tolerances, especially in pinhole alignment and end spacing.
- Heat Treatment: Key surfaces are heat-treated for HRC 50–58 hardness, improving wear resistance in heavy-cycle use.
To give you a clear look at our production and delivery process, here are real photos from our facility:
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.
These images reflect not only our large-scale manufacturing capability, but also our commitment to quality control, cleanliness, and shipment security — from the raw part to the finished product.
Compatibility & Fitment
This H-type boom bracket is compatible with:
- Doosan / Daewoo DH80
- Other variants with similar boom-arm interface geometry
