Precision Working Principle

Dual-Rope Synchronization

1. Positioning

   • Supporting ropes position grab above material

   • Closing rope release enables jaw opening

2. Material Engagement

   • Jaws penetrate material during closure

   • Optimized geometry maximizes fill rate

3. Transport & Discharge

   • Secure lifting via synchronized ropes

   • Controlled dumping at target location
