SSY004911920 Intermediate frame Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004911920 intermediate frame is a core load-bearing connecting component in the middle section of the Sany original machine, compatible with Sany excavators, rotary drilling rigs, and other tracked construction machinery. Located in the core middle section of the machine body, it connects the front and rear frames, forming a complete load-bearing frame with the left and right main beams. It bears the machine’s operating load, walking vibration, and torsional torque, and centrally distributes the impact stress from digging, climbing, and turning. It plays a crucial role in stabilizing the overall machine structure, balancing the stress on the machine body, and positioning core assembly components.
This product is integrally welded from thickened high-strength steel plates, featuring full and solid welds, high overall rigidity, and excellent resistance to torsion, compression, and fatigue. It can withstand heavy-duty and bumpy working conditions in mining, earthmoving, and infrastructure projects for extended periods. Long-term high-frequency operation, unilateral stress, and impacts on construction sites can easily lead to twisting and deformation of the old intermediate frame, weld cracking, and stress loosening, causing problems such as machine misalignment, vibration, misaligned parts, and abnormal structural noises, severely reducing operational stability and equipment lifespan. This product features original factory precision molding, standard hole positions, and accurate alignment, allowing for non-destructive replacement of old and damaged frames. It is suitable for equipment overhauls, maintenance modifications, and bulk stocking, effectively restoring the overall structural precision and reducing maintenance and failure costs.
