Beveling

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

Robotic Welding

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

Boring After Welding & Pipe Welding

Boring After Welding

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

Metal Pipe Welding

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

Reliable Components

Hardened and tempered pins used in excavator long reach boom joints
EATON high-pressure hydraulic hoses fitted on a long reach excavator boom
Hydraulic Cylinder

Hydraulic cylinders are customized from the S-ANY factory for reliable performance and long service life.

Pins

Pins are made from 40Cr material and are hardened (above 55 HRC), tempered for toughness and ground for precision, greatly extending the service life of the long boom.

Hydraulic Hoses

All high-pressure hoses use the American EATON brand for dependable pressure resistance.

Painting
KANSAI paint finish on an excavator long reach boom matching original machine color

Japan KANSAI paint is used — the same supplier used by excavator manufacturers such as HITACHI and KOBELCO. This ensures a 100% color match with original machines and a durable, professional finish.
