What Is the Function of the DH150 H-Link?
The H-link, also referred to as the H-type boom bracket, plays a vital role in maintaining structural alignment between the excavator’s boom and arm. On the DH150, this component acts as the central hinge that distributes force during digging, lifting, and arm articulation.
A high-quality H-link reduces vibration, absorbs shock, and ensures that movement between the bucket and arm remains smooth and stable. This not only prevents premature wear on surrounding parts such as bushings, pins, and hydraulic cylinders, but also enhances overall operator control and digging efficiency. In demanding environments like trenching, foundation work, or confined job sites, a reliable H-link maintains consistent performance and contributes to longer machine service life with fewer unplanned maintenance stops.
Material & Structural Features
Our DH150 H-links are made from Q345B structural steel, offering an excellent balance of tensile strength and weldability.
Each DH150 H-link undergoes a strict multi-stage manufacturing process:
- Raw Material Cutting – Q345B steel is cut according to structural requirements
- Forging & Shaping – The H-profile is forged and stamped for base form
- CNC Precision Machining – Machining of pin holes and mounting interfaces
- Heat Treatment – Key wear zones are quenched to achieve surface hardness
- Welding Inspection – Reinforcement areas are ultrasonically tested
- Surface Coating – Black rust-proof coating or primer is applied
- Final Fit Check – All dimensions are verified against OEM 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.
