Komatsu PC360 Link 207-70-Z3110

Tailored to the operating traits of Komatsu PC360 medium and large-sized excavators, the extended connecting rod we've engineered-specifically the Komatsu PC360link 207-70-Z3110-delivers vastly improved load-bearing capacity and structural stability. It excels in heavy-duty scenarios like mine stripping, highway infrastructure, and building demolition. By optimizing the connecting rod's hinge point layout and refining the extended boom design, equipment fitted with the Komatsu PC360link 207-70-Z3110 maintains a steadier bucket path during deep foundation pit digging and high-level material loading. This boosts operational efficiency by over 25% while minimizing ground compaction caused by frequent equipment movement.

The entire Komatsu PC360link 207-70-Z3110 product is forged from high-grade Q345B steel. This material uses a "low-carbon + manganese + microalloy" composition, boasting a stable yield-to-tensile ratio of 0.65 to 0.75-far lower than the 0.8 to 0.85 range of conventional steels. When facing impact loads, it offers greater safety redundancy, effectively preventing sudden fractures. After surface shot blasting, its symmetrical cyclic fatigue limit rises to over 220MPa, easily withstanding the alternating stress the connecting rod endures during excavator operation. Compared to rods made with ordinary materials, its service life is extended by 30%.
