70-ton double girder overhead crane – Provided for the Turbine plant in the Nhon Trach 3 & 4 Thermal Power Project. The product was completed and accepted by the team of engineers and workers at VINALIFT on schedule, contributing to speeding up the project coming into operation. This is the first thermal power project in Vietnam to use LNG fuel. Furthermore, this is also one of the gas turbine units with the highest capacity (over 500 MW) and gas efficiency (over 60%) worldwide. When operating, the project will help fulfill the Government’s commitment to reduce net emissions to zero by 2050 at COP26 and provide an additional 9 billion kWh of electricity/year to the National electricity system.
