CE-Approved Excavator Long Reach Boom Attachments for PC350 PC360 PC400 PC450 Excavator

Excavator long reach booms are widely used for river dredging, port construction, railway construction and groundwork projects. They deliver an extensive operating scope, high working efficiency and dependable safety on demanding job sites.

Specifications are listed per available configuration within each excavator tonnage class. Contact us for the exact configuration matching your machine model.

• 1 × suitable long boom and 1 × suitable long arm.
• 1 × suitable bucket (digging bucket or cleaning bucket).
• 4 × metal pipes and hoses, 8 × pins, 1 set of H-linkages and 1 set of lubricating pipes.
• 1 × bucket cylinder.
• The arm can reuse the existing original arm cylinder; a new arm cylinder can also be supplied on request.
• The two boom cylinders reuse the existing original boom cylinders.
• Extra counter weight available to balance the machine.
• Extra hydraulic pipelines available for rock breakers or other hydraulic attachments.

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 machine, producing a welding seam that is very solid, durable and even.

Consistent weld quality across the boom and arm structure supports long service life under heavy dredging and construction loads.

To achieve higher machining accuracy, a 30 m boring machine is used to process larger-diameter pin holes 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 configuration.

Material: 40Cr. All pins are hardened to raise hardness above 55 HRC, tempered to enhance toughness, and ground to improve precision. This greatly increases the service life of the long reach 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.
