SSY004950712 Crossbeam Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY004950712 Crossbeam Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004950712 crossbeam is a core transverse load-bearing component of the Sany original machine body. Located in a critical transverse position of the machine body, it undertakes the functions of structural connection, load support, and frame reinforcement. It can evenly distribute the working load, buffer bumps and vibrations, and improve faults such as machine body looseness, uneven stress, misalignment, and abnormal noise. The original hole positions are precise and require no modification. It can directly replace old crossbeams that are bent, rusted, or deformed, and 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 thick and dense structure that combines rigidity and toughness, offering excellent resistance to compression, bending, and impact. It stabilizes the machine’s lateral structure, disperses concentrated stress, and prevents bending, cracking, and breakage 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. Its stable frame enhances overall machine strength and safety, while reducing maintenance costs.

【Core Technical Parameters】

— Product Model: SSY004950712
— Product Type: Crossbeam (Sany original parts, special load-bearing reinforcement and connection accessories for the horizontal axis of construction machinery body)
— Compatible models: Compatible with Sany excavators, loaders, pump trucks, road rollers and other construction machinery, matching the original factory points on 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.
