With the introduction of Generation 6 mobile harbor cranes in June 2021, ESP.6 mobile harbor cranes will be replacing Model 4. These new cranes have a larger working radius of 49 m, an improved maximum lifting capacity of 125 t and higher lifting speeds of up to 120 m/min. The tower cab of the ESP.6 is around 5 m higher for 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.6B variant, they offer enhanced lifting capacity curves.
