DH55 H Link: Supporting Boom-Arm Articulation
The H-link on a Daewoo DH55 excavator plays a critical role in connecting the boom and the arm, forming the central axis of front-end movement. It allows for stable, smooth articulation while evenly distributing the hydraulic forces generated during excavation, trenching, or loading operations.
A high-performance H-link ensures:
- Reduced vibration and wear on bushings and pins
- Improved alignment during repetitive movement cycles
- Enhanced machine stability when operating on uneven or sloped terrain
For compact excavators like the DH55, the quality and fit of the H-link are especially important due to tighter operating envelopes and frequent directional changes.
Materials & Manufacturing Process
Our DH55 H-links are forged from Q345B or equivalent high-strength alloy steel, known for its excellent mechanical properties and weldability. The manufacturing process includes:
- Precision forging for internal strength and resistance to deformation
- CNC machining of pin holes and mounting surfaces for perfect alignment
- Heat treatment to achieve optimal surface hardness (HRC 50–55) while maintaining a tough core
- Anti-rust primer or black paint coating for corrosion resistance in harsh environments
Every unit undergoes dimensional inspection and hardness testing to meet strict OEM tolerance standards.
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-link is specifically designed for:
- Doosan / Daewoo DH55
- DH55-7, DH55LC, and other models in the same structural series
If you are unsure whether this model fits your excavator, just provide:
- Machine serial number
- Mounting drawing or field photos
- Bushing and pin specs
We’ll verify compatibility for you within 12 hours.
