PC360-25 Meter Extended Arm Assembly

Finite element analysis is carried out prior to manufacturing this PC360 25 meter extended arm assembly, with critical stress zones reinforced to minimise bending risks during long-reach operations.

Welded by certified welders with full penetration welds, it stands up to nonstop heavy dredging work.

It matches the factory hydraulic flow of your Komatsu PC360 perfectly, requiring no major modifications to the host excavator.

Adopting a modular split structure, it fits smoothly into a 40HQ container for ocean shipment.

Ideal for river dredging, reservoir desilting, deep foundation excavation, high slope finishing and coastal land reclamation.

We are a professional manufacturer focused on excavator attachments, especially custom long-reach booms, rock arms and demolition booms. All our long booms comply with the ISO9001 quality system and hold CE certification.

We complete cutting, bending, welding and painting in-house; we are not just a trading company. Before shipment, every boom undergoes visual inspection and dimensional checks. We maintain records for every production batch.

We have supplied numerous long-reach boom sets to overseas clients across Southeast Asia, Australia and the Middle East. We fully understand harsh on-site working conditions and design our structures for improved durability during prolonged outdoor operation. OEM & ODM custom services are available if you require alternative lengths or special working specifications.
