SSY004870711 Bucket Arm Sub-assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY004870711 Bucket Arm Sub-assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004870711 boom assembly is a core load-bearing component of the SANY excavator’s working device. Integrating the articulation and mounting base, it is responsible for digging and cutting, material lifting, and load transfer, making it a key assembly for complex boom operations. The assembly is welded from high-strength alloy plates, undergoing stress relief, precision shaping, and reinforcement treatment. It possesses sufficient rigidity and strong load-bearing capacity, resisting sand and gravel erosion and heavy-duty impacts, making it suitable for harsh construction scenarios such as earthmoving and mining.
This original manufacturer’s boom assembly employs a reinforced welding process, resulting in robust welds. It undergoes precision alignment and anti-corrosion/wear-resistant treatment, ensuring accurate hole positioning, fatigue resistance, and minimal deformation. Older booms, subjected to prolonged heavy-duty operation, are prone to issues such as plate deformation, weld cracking, loose hinge holes, and rust aging, causing operational swaying, weak digging power, movement deviation, and abnormal structural noises, potentially leading to equipment shutdown. This product is an original manufacturer’s standard part, supporting in-situ non-destructive replacement. It is suitable for equipment maintenance, overhauls, and bulk stocking, quickly restoring equipment operational accuracy and load-bearing capacity, and reducing maintenance costs.
