What Does the CAT E345 H-Link Do?
The H-link (also known as the boom foot bracket or H-shaped bracket) is a critical connection point between the boom and bucket linkage system of the excavator. On large machines like the CAT E345, it plays a crucial role in:
- Distributing dynamic digging forces from the bucket to the arm
- Supporting smooth bucket articulation and consistent breakout force
- Maintaining alignment of link rods and pins under high-load conditions
- Withstanding repeated impact and torsion in harsh working environments
This component must be robust, precisely machined, and wear-resistant — especially for heavy-duty excavation and mining operations where the E345 operates.
Materials & Manufacturing Process
We manufacture our E345 H-links using high quality alloy steel, selected for its strength, weldability, and resistance to cracking. The production process includes:
- Closed-die forging for refined grain structure and reduced internal defects
- CNC machining on all pinholes and bearing surfaces for exact alignment
- Heat treatment to achieve required hardness at critical wear points
- Anti-rust surface treatment, such as black oxide, phosphate, or painting
Each part undergoes rigorous dimensional and hardness inspection before packaging.
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.
OEM Fitment and Compatibility
This E345 H-link is designed to match the following machines:
- Caterpillar E345, E345B, E345C, E345D
- Other CAT 345 variants with matching boom and linkage specifications
If you're unsure, send us your machine model, serial number, or technical drawing, and our engineers will assist within 12 hours.
