Heavy-Duty Long Reach Boom and Stick for R210 R220 R260 R300 R305 R330 R340 Hyundai Excavator

Our heavy-duty long reach boom and stick assemblies are engineered for Hyundai excavators in the R210, R220, R260, R300, R305, R330 and R340 classes. They extend working range for river dredging, port construction, railway construction and ground-level (gro-underwork) construction, delivering a wide operating scope with high efficiency and high safety.

Excavator long reach booms are widely used for dredging rivers, port construction, railway construction and ground-level construction. The extended configuration provides a high extensive operation scope, high efficiency and high security on demanding job sites.

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

• Beveling: all steel plates are 45° beveled by a beveling machine before welding.
• Robotic welding machine: main welding is performed by robotic machine.
• Weld area: the welding seam is very solid, durable and even.

• Boring after welding: to achieve higher machining accuracy, we operate a 30 m boring machine used to process larger-diameter pin holes after welding. It meets micrometer accuracy demands and ensures the two pin centers stay in one line.
• Metal pipe welding: our metal pipes are welded by robotic welding, which prevents oil leakage more effectively than manual welding.

• Hydraulic cylinder: customized from the S-ANY factory.
• Pins: material 40Cr; all pins are hardened (hardness above 55 HRC), tempered (for toughness) and ground (for precision), greatly increasing the service life of the long boom.
• Hydraulic hoses: all high-pressure hoses use the American EATON brand.

We use Japan KANSAI paint, the same supplier used by excavator factories such as HITACHI and KOBELCO. This ensures the color matches original machines 100% and guarantees a durable, factory-grade finish.
