All steel plates are 45° beveled by a beveling machine before welding to ensure full penetration and structural integrity.

Main welding is performed by robotic welding machines, producing weld seams that are very solid, durable, and even.

To achieve higher machining accuracy, a 30-meter boring machine is used to process larger-diameter pin bores after welding. It meets micrometer-level accuracy demands and ensures both pin centers remain in one line.

Metal pipes are welded by robotic welding, which effectively prevents oil leakage compared with manual welding.

Hydraulic cylinders are customized from the S-ANY factory to match the long reach boom requirements.

Material: 40Cr. All pins are hardened to enhance hardness above 55 HRC, tempered to enhance toughness, and ground to enhance precision — greatly increasing the service life of the long boom.

All high-pressure hoses use the American EATON brand for reliable performance in demanding conditions.

JAPAN KANSAI paint is used — the same supplier used by excavator factories such as HITACHI and KOBELCO. This ensures the color matches original machines 100% and delivers a durable, professional finish.
