Model 2 Mobile Harbor Cranes

Ideal for small ports

The Konecranes Gottwald Model 2 Mobile Harbor Crane is the first member of our family of small mobile harbor cranes. It has a number of variants specially developed for use in small river and maritime ports, or where quayside space is limited. As with all Konecranes Gottwald mobile harbor cranes, the Model 2 is available as a mobile harbor crane, portal harbor crane, crane on barge and rubber-tired portal harbor crane.

The Model 2 combines the mobility of the rubber-tired mobile harbor crane with the drive-under capability given by portal design and bears the type designation G HRK rubber-tired portal harbor crane. Thanks to its tight turning circle, crab steering and ability to turn on the spot, this crane is easy to maneuver and quick to position alongside ships.
