RTG/RMG Height Raising
Technical SolutionsHeight raising solutions for RTG (Rubber Tyred Gantry) and RMG (Rail Mounted Gantry) cranes, converting from 4+1 to 5+1 or 5+1 to 6+1 stacking tiers to maximize container yard capacity.
DETAILS
Bac Au provides height raising solutions for RTG and RMG cranes, increasing container stacking capacity within the same yard footprint to meet growing cargo throughput demands.
Conversion options:
• From 4+1 to 5+1: Add 1 stacking tier (approximately 2.6m height), increasing yard capacity by 25%. Ideal for ports needing capacity expansion without expanding yard area.
• From 5+1 to 6+1: Add 1 tier, reaching maximum stacking height of 6 containers + 1 operational clearance. Solution for high-density major container terminals.
Implementation process:
• Survey and structural assessment: evaluate load capacity of legs, main beams, rail systems. Reinforcement design: FEA calculations, leg extension section design. Workshop fabrication per AWS D1.1 welding standards.
• On-site construction: leg cutting, extension installation, field welding, cable and electrical system adjustments. Load testing and acceptance after upgrade.
Benefits: 20-25% yard capacity increase without expanding area, 60-70% lower cost than purchasing new cranes, 3-4 weeks construction time per crane.
