Let’s talk about how our ESP.6 cranes can improve your terminal

Discover our crane types

Konecranes Gottwald Mobile Harbor Cranes have been developed for all types of terminals. They can be moved quickly and easily around the entire terminal on their rubber-tired chassis. For terminals with lower quay loads and smaller surface areas, we offer other crane types – mounted on:



For more than 20 years, we have offered mobile harbor crane technology on portals, for terminals with lower quay loads or existing rail infrastructure. The portals are adapted to the existing track width, the required clearance height and the rail load.



We have offered our Konecranes Gottwald Cranes on Barge for terminal-independent operation for more than 15 years. Whether on the shore, river or open sea, our cranes are reliable and powerful cargo handling machines.



Our mobile harbor crane technology is also generally designed to be mounted on a pedestal directly on the terminal floor. This is one option for terminals with a small quay area.
