On May 11, Tan Cang Technical Services JSC (tancangtech) and Huynh Thy Trading & Service Co., Ltd., in strategic collaboration with Mitsui E&S Group (MES) of Japan, held the formal completion and handover ceremony for the first 4 Rubber-Tired Gantry Hybrid cranes (Hybrid RTGs) manufactured directly in Vietnam.
This achievement represents a monumental breakthrough in modernizing port equipment and marks a landmark green technology transfer milestone between Vietnam and Japan, advancing sustainable, efficient, and eco-friendly maritime logistics.
Strategic Domestic Manufacturing of Hybrid RTG Cranes in Vietnam
RTG (Rubber-Tired Gantry) cranes are specialized heavy lifting equipment designed for high-density container yard handling. Featuring rigid portal steel frames and multi-wheel steering bogies, RTGs maximize container stacking density across busy terminal blocks.
The Hybrid RTG is a next-generation RTG crane engineered to minimize fuel consumption and extend mechanical lifespan. In this architecture, an auxiliary diesel generator is utilized solely to recharge a high-capacity energy storage battery system, rather than driving the hoist and gantry motors directly under erratic peak load surges as in conventional diesel RTGs.
This design allows the crane to utilize a significantly smaller, lighter diesel engine operating steadily at optimal RPM, minimizing fuel consumption and drastically reducing engine wear. Furthermore, the specialized battery bank captures and stores regenerative electrical energy produced when lowering heavy containers.
Through this advanced hybrid powertrain, the crane achieves a 60–64% fuel saving and a corresponding massive reduction in CO₂ exhaust emissions compared to conventional diesel RTG models.
Compared to all-electric eRTGs—which are powered from the grid via motorized cable reels or busbars, offering zero direct emissions but requiring extensive civil power infrastructure and limiting inter-block mobility—Hybrid RTGs deliver complete yard mobility without requiring costly grid civil works, allowing seamless crane repositioning across container yards.
Beyond cutting fuel and maintenance costs, Hybrid RTGs significantly reduce operating noise and vibration, providing superior ergonomic comfort for crane operators and extending structural asset lifespan—core criteria for modern sustainable container terminals.
Affirming Tan Cang Tech’s RTG Crane Erection & Manufacturing Excellence
With trusted partnerships from Huynh Thy and Mitsui E&S, Tan Cang Technical Services JSC flawlessly executed the erection, assembly, and commissioning of 04 fuel-efficient Hybrid RTG cranes with outstanding precision and rapid build times, earning high praise from Japanese engineering specialists.
The delivered Hybrid RTG cranes achieve a domestic localization ratio of up to 50% for this pioneering crane model in Vietnam. Backed by deep technical expertise and rigorous leadership, the project was delivered ahead of schedule with zero safety incidents.
The engineering milestones achieved in this project solidify Tan Cang Tech’s position as Vietnam’s premier specialist in the erection, assembly, retrofit, and manufacturing of RTG cranes, eRTGs, and next-generation eco-friendly port machinery.
As the technical backbone of Saigon Newport Corporation, DVKT played the central role in structural assembly, installation oversight, and load commissioning. Our engineers ensured absolute compliance with rigorous Japanese technical criteria while conducting full safety certifications and fine-tuning drive automation—vital proof of DVKT’s technical leadership in realizing the “Green Port” strategic vision.
Vast Market Growth Potential
Vietnam currently boasts over 30 major container seaports, most of which still rely on older diesel RTG cranes characterized by high fuel costs and heavy emissions. As national container throughput expands steadily year after year, the demand for energy-efficient, green terminal equipment has become an urgent priority.
Importantly, the Government’s National Logistics Development Strategy to 2030 targets a minimum 10% transport emission cut while incentivizing investments in green terminal machinery. This policy environment provides a powerful catalyst for the widespread rollout of Hybrid RTGs and eRTGs across Vietnam.
Tan Cang Tech is uniquely positioned to deliver complete turnkey decarbonization solutions for container ports: from new-build eRTG construction and diesel-to-electric eRTG retrofits (which have saved Saigon Newport hundreds of billions of VND annually) to cutting-edge domestic Hybrid RTG manufacturing—ushering in a new era of green terminal development across Vietnam and expanding into Southeast Asia.
