With the introduction of Generation 6 mobile harbor cranes in June 2021, ESP.7 mobile harbor cranes will be replacing Model 6. These new cranes also have a working radius of 51 m, a maximum lifting capacity of 125 t and lifting speeds of up to 120 m/min. The tower cab on the ESP.7 is around 2 m higher compared to the long-tower Model 6 to provide the best view of the working environment. The classifications have been increased, doubling the product lifecycle in heavy-load, container and general cargo operation, for example. As four-rope grab cranes in the ESP.7B variant, they offer a 63-t and a 52-t grab load curve.
