📌 Key Selection Criteria

‌
1️⃣ ‌Compatibility‌: Ensure compatibility with excavator tonnage
2️⃣ ‌Steel Thickness‌: Key components (jaw plates/brackets) require ≥25 mm wear-resistant steel plates
3️⃣ ‌Hydraulic System‌: Opt for dual-circuit rotation motors; pressure recommended at 210-350 bar (match host machine)
4️⃣ ‌Sealing‌: Prioritize high-quality sealing components

‌💥 Common Failure Points

‌
⚠️ Swivel joint oil leakage (45% failure rate)
⚠️ Jaw plate fracture (caused by overload)
⚠️ Cylinder internal leakage (seal aging)
⚠️ Pin shaft wear (insufficient lubrication)

‌✅ Prevention Measures

‌
🔸 Daily hydraulic oil level and pipeline inspection
🔸 Lithium-based grease replenishment every 50 operating hours
🔸 Avoid continuous rotation beyond 270°
🔸 Install overload protection valves (pressure ≈110% system pressure)
