Compact and lightweight–such is the most common requirement for the gearboxes of emission-free, electric drives. With seven basic gearboxes, the LPI series by Liebherr fulfils exactly this need for high power density. With their low weight, reduced installation space and torque ranges from 20,000 Nm to 350,000 Nm, they are ideally suited as drives for crawler and crawler undercarriages. Customized large gearboxes are even available up to the maximum torque of 2,300,000 Nm.

NGC Gears, one of the world’s largest wind power gearbox manufacturers, has completed the installation of two additional EndoFlex generators from UPC-Marathon, a Nitrex company, at its new facility in Jinhu, China location. This acquisition brings the total of generator sets to five since 2022, collectively generating an impressive 800 m³/h (22,252 ft3/h) capacity of endothermic gas supplied to carburizing and hardening furnaces used for processing various gear components. The latest installations in February and March of 2024 support the heat-treating operations of the company’s wind energy gearbox production.

Wind power has emerged as one of the most important sources of renewable energy in recent years. The global wind power capacity was estimated to be 837 gigawatts in 2021 (statista.com). In the United States alone, wind is the largest source of renewable electricity, providing 10.2 percent of the country’s electricity and still growing (cleanpower.org/facts/wind-power/). However, to ensure maximum power generation, the efficiency and reliability of the wind turbine are critical.
