SSY004917771 Left Rear Crossbeam Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004917771 left rear crossbeam is a core load-bearing component of the Sany original machine body. Installed at the left rear of the machine body, it is used for lateral support, structural reinforcement, and component positioning. It can distribute the operating load, buffer bumps and vibrations, and improve faults such as machine body looseness, structural misalignment, abnormal noise, and deformation. The original hole positions are precise and require no modification. It can directly replace old and damaged parts and is suitable for equipment maintenance, new machine matching, and bulk stocking.
This product is a key lateral load-bearing component of the machine body, integrally formed from high-strength alloy structural steel, providing ample rigidity, resistance to compression and bending, and resistance to impact and fatigue. It balances the force on the left rear of the machine body, disperses concentrated stress, improves the stability of the tail frame, and avoids deformation and cracking caused by heavy-load bumps. Suitable for harsh working conditions such as mining, infrastructure construction, and heavy earthmoving, it is not prone to rust or deformation during long-term operation, stabilizes the overall machine structure, and effectively reduces equipment failure and maintenance costs.

【Core Technical Parameters】

— Product Model: SSY004917771
— Product Type: Left Rear Crossbeam (Sany Original Part, Special Accessory for Reinforcing the Lateral Load-Bearing Capacity of the Left Rear of Engineering Machinery)
— Compatible models: Compatible with Sany excavators, loaders, pump trucks, road rollers and other construction machinery. Matches the original factory position on the left rear of the machine body and can directly replace old and damaged crossbeams.
— Main body material: High-strength alloy structural steel integral molding, hard texture, strong lateral load-bearing capacity, resistant to bending, impact, and high frequency vibration of equipment.
— Operating temperature range: -45℃~+125℃, wide temperature adaptability, stable structure under high and low temperature conditions, no brittleness, deformation or failure issues.
— Structural design: The original factory-precisely molded horizontal structure distributes the stress evenly, effectively improving the overall rigidity and stability of the left rear frame of the fuselage.
— Load-bearing capacity: Meets the original manufacturer’s load-bearing standards, can withstand high-frequency dynamic loads, and is not prone to deformation, collapse, or structural loosening under long-term heavy loads.
— Surface treatment: Rust removal and passivation + electrostatic powder coating for corrosion protection, resistant to salt spray, aging, and oil stains, and resists construction site corrosion and rain oxidation.
— Dimensional accuracy: Original factory precision tolerances, 1:1 original fit for contours and holes, no damage, no assembly deviations or loose gaps.
— Installation method: Fixed with original standard hole bolts, no modification required, easy to disassemble and assemble, and supports multiple maintenance and reuse.
— Adaptability to working conditions: Suitable for all-weather field construction, resistant to bumps and vibrations, and heavy loads, eliminating crossbeam deformation, structural displacement, and machine body loosening.
— Service life: Low wear under harsh working conditions, superior rigidity, impact resistance and corrosion resistance compared to ordinary parts, resulting in a longer service life.

Adaptable to all construction scenarios of engineering machinery, the SSY004917771 original left rear crossbeam, with its high rigidity load-bearing structure and excellent vibration and impact resistance, is precisely matched with the original factory. It reinforces the left rear frame of the machine body, balances the load of the whole machine, and improves problems such as machine body deformation, component misalignment, and structural noise. It is a high-quality original load-bearing part for SANY equipment maintenance and replacement, whole machine matching, and bulk procurement.
