Heavy-Lift Discharging & Unloading Support Project: 12 Kalmar RTG Cranes

The engineering project to support the roll-off unloading, receiving, and commissioning of 12 new Kalmar RTG cranes at Tan Cang – Cat Lai Port represents a major milestone in the overarching modernization and green terminal transition driven by Saigon Newport Corporation and Tan Cang Technical Services JSC (tancangtech).

This project is an integral element of Tan Cang Tech’s long-term strategy to master advanced port crane technologies, expanding technical capabilities across new-generation, energy-efficient container gantry cranes with lower lifecycle maintenance and operational costs.

Project Information

Client & Technical Partners: Saigon Newport Corporation (SNP), Unico Vina

Execution Location: Tan Cang – Cat Lai Port (Cat Lai Container Terminal)

Execution Period: Q2/2025

Scope of Work: Technical Support & Roll-off Unlashing for 12 Kalmar RTGs

• Technical unlashing and seafastening release support for 12 RTG cranes
• Supply of specialized heavy bridging ramps and transition equipment for crane roll-off from heavy-deck vessel to terminal quay
• Provision, hookup, and continuous operation of high-capacity mobile diesel generators to supply temporary electric power for self-propelled gantry travel from berth to final yard staging positions
• Engineering guidance and escort to safely maneuver RTG cranes across terminal traffic lanes to designated yard blocks
• Technical advisory, real-time troubleshooting, and seamless inter-agency coordination with partner teams to ensure total marine and heavy-lift safety

Engineering Challenges & Solutions

Drawing on extensive heavy-lift logistics experience across dozens of complex port crane installations, Tan Cang Tech effortlessly managed the technical support operations despite tight tidal windows and demanding spatial constraints.

Partner & Client Feedback

1. Exceptional technician professionalism: While operating in a technical support capacity, Tan Cang Tech demonstrated the fastest reaction times and highest initiative in troubleshooting unexpected on-site mechanical and electrical hurdles.
2. Comprehensive heavy equipment availability: During initial roll-off operations, the first RTG cranes encountered steep gradient resistance on the standard shipboard ramp due to narrow deck run-up clearances, triggering gantry drive overcurrent protection trips. Tan Cang Tech immediately provided its proprietary heavy bridging ramp system featuring lower incline angles, allowing all subsequent RTG units to roll off smoothly, safely, and ahead of schedule.
