This excavator U Yoke (also named I-beam, bucket connecting link, U bracket) is professionally customized and produced for
Hitachi ZAX200-5G (ZX200-5G) medium hydraulic excavator. It is the core force-bearing connecting component between bucket cylinder, arm and bucket, undertaking huge impact load during digging, loading, earthmoving and mining operations. Our products adopt integrated forging & high temperature quenching technology, effectively resisting deformation, cracking and abrasion, perfectly replace original factory spare parts, widely sold to Russia, Turkey, Middle East, Southeast Asia construction machinery maintenance markets.
Core Material & Production Craft Advantages
- 1.Raw Material: High-strength wear-resistant alloy structural steel (40CrMnMo alloy steel), higher tensile strength than ordinary Q355 steel, strong anti-fatigue performance under long-period vibration impact
2.Integral Precision Forging: One-time hot forging forming, no splicing welding inside main force area, eliminate welding crack hidden danger
- 3.Dual Heat Treatment Process: High temperature quenching + tempering treatment, internal metal structure compacted, surface hardness balanced; resistant to bending deformation, not easy to break under heavy load
- 4.CNC Precision Machining: All pin hole inner walls finely bored, tolerance strictly controlled, smooth matching with pin shaft & bushing; reserved independent grease injection channel, convenient daily lubrication maintenance
5.Anti-corrosion Finish: Whole body rust-proof primer + heavy-duty yellow finish paint, adapt rainy, muddy, mining dusty harsh working environment
Application Working Conditions
Perfectly applicable for Hitachi ZAX200-5G excavator daily operation scenarios:
- Highway, municipal road construction, foundation earthwork excavation
- Water conservancy project, river dredging, slope trimming
- Quarry auxiliary mining, stone loading, gravel handling
- Rural reconstruction, land leveling, building demolition
