What Is the Function of the DH500 H-Link?
The H-link (also known as the H-type boom bracket) is a central structural component that connects the boom and arm of the excavator. On large machines like the DH500, this component plays a critical role in:
- Transferring hydraulic power smoothly between the boom and the arm
- Aligning the movement of the working equipment
- Distributing heavy digging and lifting loads during operation
- Absorbing shocks and minimizing wear on adjoining parts such as bushings, pins, and hydraulic cylinders
A robust H-link ensures consistent motion control and protects the overall stability of the excavator’s front-end assembly, especially in high-impact tasks like quarrying, deep trenching, or rock excavation.
Material & Structural Features
To meet the extreme demands of the DH500 class machine, our H-links are:
- Forged from high-grade steel, such as 45# or 35CrMo, offering high tensile strength and resistance to deformation
- Subjected to controlled heat treatment to enhance surface hardness (typically HRC 50–58) while maintaining core toughness
- CNC-machined with tight tolerances to ensure accurate fitment with the boom and arm pinholes
This combination of materials and craftsmanship ensures the component will maintain integrity under long-term, repetitive stress.
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 compatible with the following:
- Daewoo / Doosan DH500
- DH500LC, DH500-7, and other variants using the same boom-arm connection geometry
While original part numbers for DH500 H-links can vary based on configuration, you can send us your serial number, old casting code, or technical drawing, and we’ll verify compatibility within 12 hours.
