Product Introduction:
The excavator intermediate support seat, also referred to as the spindle support base and rear mounting support, serves as a key load-bearing structural part connecting the excavator arm and boom assembly. It undertakes critical load transmission tasks, maintains overall structural stability, and ensures smooth and flexible mechanical operation during equipment movement. As intelligent lubrication design and predictive protection technology continue to gain widespread application in the construction machinery industry, this core support component will evolve toward integrated development featuring self-adaptive adjustment, intelligent maintenance and extended service lifespan. It will further become an indispensable core competitive component for high-end and high-performance excavator models.
Product Advantages:
We implement full-cycle quality monitoring from raw material incoming inspection to finished product delivery. With mature forging technology and standardized machining management, we guarantee stable product performance and high dimensional consistency. We support flexible custom development & mass production, deliver cost-effective forged parts with stable lead time, and provide tailored manufacturing solutions to fit diverse industrial operating scenarios.
Production Process:
Raw Material Inspection → Cutting → Forging → Heat Treatment/Tempering → Shot Blasting → Rough Machining → Ultrasonic Testing (UT) → Final Inspection → Cleaning Packaging
Packaging and Shipping:
Before shipment, all products go through a complete standardized pre-delivery procedure: professional surface cleaning, formal specification labeling, and tailored anti-rust & moisture-proof protection according to product material characteristics. Each piece is then subject to rigorous manual appearance inspection and visual quality check to eliminate scratches, deformation and any cosmetic or structural defects. Qualified products are packaged with shockproof, compression-resistant and moisture-proof protective materials, then orderly categorized and stored in the standardized warehouse. The whole strictly controlled process fully guarantees product intactness, stable quality and perfect condition, laying a reliable foundation for safe logistics delivery and customer use.
Company Strength:
Drawing on almost 30 years of development, we have expanded our reach globally. Our components are widely adopted across multiple core industrial sectors. We enjoy stable collaboration with prestigious overseas clients and leading domestic equipment makers, with overseas business exceeding half of our total turnover. Our flagship forgings and lifting hook assemblies lead the domestic market, fully demonstrating our reliable quality, solid strength and outstanding market advantages.
