Core Structural Innovation

1. True L-Leg Advantage
→ Integrated L-shaped legs + bottom beam system (FEM 1.001 verified)
→ 40% reduced floor obstruction vs. conventional gantries
→ Optimized hook approach: 0mm end clearance at cantilever ends

2. Extreme Environment Resilience

• Corrosion Defense: Triple-layer coating (SA 2.5 blast + 280μm Zn-rich epoxy + PU topcoat)

• Component Protection: IP55 hoists / IP65 control cabinets / A4 stainless bolts

• Temperature Range: -20°C to +40°C (Arctic/Wind kits to -40°C)
