SSY004950720 Middle crossbeam Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004950720 central crossbeam is a core transverse load-bearing component in the middle of the Sany original machine body. Located in the stress-bearing area of ​​the central body, it is responsible for structural connection, load support, and frame reinforcement. It can evenly distribute the central working load, buffer bumps and vibrations, and improve problems such as frame looseness, uneven stress, misalignment, and abnormal noise. The original hole positions do not require modification and can directly replace old crossbeams that are bent, rusted, or deformed. It is suitable for equipment maintenance, new machine matching, and bulk stocking.
This product is made of high-strength alloy structural steel in one piece, with a robust structure that combines rigidity and toughness, exhibiting excellent resistance to compression, bending, impact, and fatigue. It stabilizes the transverse structure in the middle of the machine body, disperses concentrated stress, and prevents bending, cracking, and loosening caused by heavy-load vibration. Suitable for harsh working conditions such as mining, infrastructure construction, and heavy earthmoving, it is resistant to rust, deformation, and damage even after long-term operation, effectively reinforcing the machine frame, improving overall stability, and reducing maintenance costs.

【Core Technical Parameters】

— Product Model: SSY004950720
— Product Type: Middle Crossbeam (Sany original parts, special load-bearing reinforcement and connection accessories for the middle of the body of construction machinery)
— Compatible models: Compatible with Sany excavators, loaders, pump trucks, road rollers and other construction machinery. Matches the original factory points in the middle of the machine body and can directly replace damaged crossbeams.
— Main body material: High-strength alloy structural steel integral molding, hard and thick, strong load-bearing capacity, resistant to bending and impact, and resistant to high-frequency vibration loads of equipment.
— Operating temperature range: -45℃~+125℃, wide temperature adaptability, stable structure in alternating high and low temperature environments, no brittleness, deformation or failure issues.
— Structural design: The original factory precisely molded the parts to fit the horizontal structure in the middle of the body, which is reasonable in terms of stress and load distribution, and improves the overall stability of the middle of the body.
— Load-bearing capacity: Meets the original manufacturer’s load-bearing standards, can withstand heavy dynamic pressure, and is not prone to bending, collapse, or structural loosening during long-term operation.
— Surface treatment: Rust removal and passivation + electrostatic powder coating, strong paint adhesion, salt spray resistance, anti-aging, oil resistance, and resistance to construction site corrosion.
— Dimensional accuracy: Original factory precision tolerance, 1:1 original fit, tight fit without deviation, no assembly gaps or looseness issues.
— Installation method: Fixed with original standard bolts, no modification required, efficient disassembly and assembly, and supports multiple maintenance and reuse.
— Adaptability to working conditions: Suitable for all-weather field construction, resistant to bumps, vibrations, and heavy loads, eliminating beam deformation, frame displacement, and structural loosening.
— Service life: Low wear and tear under harsh working conditions, superior rigidity, impact resistance and corrosion resistance compared to ordinary beams, resulting in a longer service life.
— Execution standard: Complies with SANY’s original process specifications, and has passed load-bearing, vibration resistance and corrosion resistance tests, with stable quality and reliable compatibility.

The SSY004950720 original central crossbeam structure is stable and has strong load-bearing capacity. With its excellent rigidity and compatibility with the original factory, it reinforces the central frame of the machine body, distributes the working load evenly, and improves problems such as uneven structural stress, vibration and abnormal noise, and loosening. It ensures the stable operation of the whole machine and is a high-quality original load-bearing component for SANY equipment maintenance, whole machine matching, and bulk procurement.
