Key Configurations & Manufacturing

Advanced Welding: Beveled steel plate edges via milling machines before robotic welding for solid, even, and durable seams.
Premium Materials: Constructed with Q690D high-strength steel (equivalent to Weldox 700) for exceptional performance in tough conditions.
Hydraulic Precision: Equipped with S/ANY brand bucket cylinders and American "EATON" high-pressure hoses.
Enhanced Durability: All pins are hardened (above 55HRC), tempered for toughness, and grinded for precision to maximize service life.
Superior Finish: Utilizes Japanese "KANSAI" paint for a 100% color match with original machines (Hitachi, Kobelco, etc.) and long-term fade resistance.
High Accuracy: Post-welding boring process using 30m boring machines ensures micrometer accuracy for pin housing.

Frequently Asked Questions

What material is used for the long reach boom and arm?

We use Q690D high-strength steel plates for the entire boom and arm construction. This material is equivalent to Weldox 700 in terms of strength, providing excellent durability in various working conditions.

Is the welding done manually or by machines?

We utilize robotic welding machines to ensure that the welding seams are solid, durable, and perfectly even. Before welding, all steel plate edges are beveled using a milling machine.

Will the paint match my original excavator?

Yes, we use Japan "KANSAI" paint, which is the same supplier used by major excavator factories like Hitachi and Kobelco. We can insure a 100% color match that will not fade during long-term use.

What specific excavator models can use this LB-20 long reach boom?

The LB-20 model is specifically designed for 20-22 ton excavators. However, we can provide custom long reach solutions for almost all excavator models.

How do you ensure the precision of the pin holes?

We perform a boring process after welding using a 30m boring machine. This allows us to achieve micrometer accuracy for larger diameter pin hoses, ensuring a perfect fit and smoother operation.

What hydraulic components are included in the standard package?

The standard package includes American "EATON" brand high-pressure hoses and S/ANY brand bucket cylinders. We also provide all necessary seamless steel tubes and lubricating pipes.
