- Using rails and load-spreading beams in specific conditions where infrastructure allows
- Precise positioning and lowering with laser and tilt-sensor systems to ensure structural integrity

2. Internal Relocation Within or Between Ports

SPMTs are used exclusively to lift and move STS cranes in full structure
Includes temporary foundation reinforcement and ground load preparation
Positioning, rail alignment, and reactivation at the new site without disrupting operations
