Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
What Is the Function of the SK60 H-Link?
The H-link—also referred to as a boom-arm connecting bracket—is a key structural joint that connects the boom and stick (arm) of the excavator, forming part of the front working group. It serves as a pivot link that allows synchronized movement while withstanding constant mechanical stress during digging, lifting, trenching, and material handling.
In compact excavators like the Kobelco SK60, the H-link plays an even more crucial role. These machines are frequently used in tight working conditions such as urban construction, agricultural land development, and trenching along narrow spaces. With shorter boom-stroke angles and frequent hydraulic actuation, the H-link must ensure precise articulation and stable load transfer between the boom and stick.
Material Specifications and Surface Treatment
We manufacture the SK60 H-link using Q345B or Q235B structural steel, known for high tensile strength and weldability. Each unit is forged to improve internal density and resistance to deformation.
Key material and treatment features
Material Options: Q345B (high yield strength) or Q235B (cost-effective with solid performance)
Surface Treatment
- Shot blasting to remove mill scale and improve coating adhesion
- Primer coating or electrophoresis painting for enhanced corrosion resistance
- Precision Reaming: For both bore ends, ensuring optimal pin fit and smooth movement
These processes ensure the H-link maintains excellent structural integrity even in wet, muddy, or abrasive operating conditions.
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.
OEM Fitment & Compatible Machine Models
This H-link is designed for perfect OEM compatibility with the Kobelco SK60 series, including the following variants:
- SK60-3 / SK60-5 / SK60-6 / SK60-8
- Other Kobelco compact-class machines with the same boom-arm interface geometry
If your current part has a different casting code or is a custom build, feel free to share your technical drawing or serial number — our team will verify compatibility within 12 hours.

- Ultrasonic flaw detection for internal defects
- Batch hardness testing to ensure consistency across forged units
Our QC system ensures your replacement part arrives ready for immediate, hassle-free installation.
Installation & Maintenance Tips for Longevity
To maximize the working life of your SK60 H-link:
- Grease pin interfaces every 100–200 hours depending on jobsite dust levels
- Inspect pin holes regularly for signs of elongation or bushing wear
- Avoid overloading the boom-arm assembly in one-sided or high-leverage operations
- Replace both the link rod and H-link together if wear is present on both sides
