Die Herausforderung

  • Z-axis Stability: 4.3m telescopic stroke with 200kg load risks scissor arm deflection.
  • Cost & Lead Time: High price/delivery of ABB Ex brakes requiring alternative solutions.
  • Cable Management: Large drag chain bend radius (≥200mm) for multi-cable protection.
  • Space Constraints: Dense equipment layout demands compact track/support design.

Lösungen

  • Z-axis Reinforcement: Manganese steel arms + cross roller guides enhance stiffness; dual motors with encoders limit deflection to 8.6mm.
  • Electromagnetic Brake: ATEX-certified brakes (200N·m torque) cut costs by 40% and lead time by 50%.
  • Layered Drag Chains: Separated power/signal cables in 180mm bend radius chains for 500k cycles.
  • Modular Tracks: Pre-assembled quick-release tracks + embedded supports save 15% space.

Vorteile

✅ Full Ex Safety: 12 ATEX-certified motors/switches for IIB T4 zones.
✅ Heavy & Long Reach: Z-axis 4.3m/200kg with <0.2% deflection.
✅ High Flexibility: 0-12m/min speed control, 95% coverage per unit.
✅ Easy Maintenance: Layered chains + modular tracks cut downtime by 50%.
✅ Cost-Effective: 30% savings with alternative brakes, 8-week delivery.
