The H Link (often called the “bucket H-link” or “boom-to-bucket connecting link”) is one of the most critical structural components in the front working attachment of an excavator. For Komatsu PC60, the H Link plays a central role in coordinating the movement between the bucket, bucket link, and the hydraulic cylinder. Its rigidity, internal bushing precision, and overall geometry directly influence bucket breakout force, digging stability, and overall operating efficiency.
Because the PC60 is widely used in foundation work, road construction, landscaping, municipal projects, and small-to-medium earthmoving operations, the H Link must withstand repeated impact loads and high-frequency articulation cycles. A high-performance replacement H Link ensures smoother bucket control, longer service intervals, and reduced play in the working device.
Structural Role of the PC60 H Link
Unlike simple hinge components, the H Link is engineered with a dual-arm symmetrical structure resembling an “H” shape. This form distributes load evenly across both sides of the bucket, maintaining balance and preventing torsional distortion during heavy operation.
Its key functions include:
- maintaining the correct geometry between bucket and link
- stabilizing the bucket during breakout, lifting, and curling
- transmitting hydraulic cylinder force efficiently
- reducing lateral stress and preventing misalignment under heavy load
- ensuring smooth articulation even after extended working hours
With well-machined pin holes and high-strength bearing surfaces, the H Link acts as a precise mechanical connector that supports both motion and force transfer.
Precision Machining & Surface Treatment
For Komatsu PC60, tight tolerances are essential to preserve accurate bucket movement. Each H Link is produced with CNC machining equipment to ensure consistent pin clearance and smooth bushing fitment.
Additional treatment includes:
- stress-relief heat treatment to improve toughness
- semi-automatic welding reinforcement around high-load edges
- anti-corrosion surface coating to protect against moisture, dirt, and abrasive media
The result is a stable, long-life structural link capable of handling demanding excavation loads without deformation.
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.
Bushing & Lubrication Interface
The H Link operates through continuous rotation with the bucket pin and H-link pin, meaning lubrication and internal wear protection are crucial. Our PC60 H Link supports both standard bronze bushings and high-hardness bi-metal bushings, depending on the customer’s requirement.
Optimized features include:
- precision-fit bushing seats for reduced internal play
- smooth surface finish for uniform pin loading
- optional greasing channels to maintain lubrication circulation
- enhanced wear prevention for long-term rotational performance
These features help maintain bucket stability and eliminate rattling or uneven movement during operation.
Compatibility
This H Link is fully compatible with Komatsu PC60 and PC60-5/6 series excavators, supporting both OEM replacement and aftermarket maintenance needs. Custom versions for specific bucket styles are also available.
