Konecranes supplied a mobile harbor crane with a new drive concept to Weserport in Bremen in June 2018. Weserport uses the crane in Terminal 1 of Bremen's Industriehafen for loading and unloading general cargo and handling project loads.

The new Model 6 mobile harbor crane in the G HMK 6507 two-rope variant offers Weserport a maximum lifting capacity of 125 tons and a radius of up to 51 meters. It features the new drive concept recently unveiled at TOC Europe 2018, one of the world's leading shipping, ports and terminal events. The drive concept incorporates Konecranes' proven hybrid technology, which includes a new 625 kW diesel engine in addition to electrostatic short-term energy storage media (ultracaps). 

Heiner Delicat, Managing Director Weserport: "With the mobile harbor crane from Konecranes, we have opted for a highly productive and eco-efficient crane with a new-generation drive system. The maximum lifting capacity of the new crane is more than twice as high as that of our old portal slewing crane, enabling us to develop and serve new areas of business. Our crane operators received training from Konecranes in Düsseldorf to exploit the crane's full potential. They value the crane's performance and, above all, its user-friendliness".

In its new drive concept for mobile harbor cranes, Konecranes combines, depending on the crane model, Volvo Penta 625 kW diesel engines with one or more 125 kW ultracap modules. The new concept, which includes optional SCR exhaust technology, thus not only meets the EPA Tier 4f emission standards, but also the requirements of the EU Stage V.

Giuseppe Di Lisa, Sales & Marketing Director of Konecranes’ Business Unit Mobile Harbor Cranes: "After extensive and successful tests during terminal operation, we are successively introducing the new drive concept in our entire range of mobile harbor cranes. During the transition phase, all current drive configurations will remain available. Our customers benefit from numerous advantages of the new drive concept, including reduced fuel consumption and exhaust emissions. The concept also allows downsizing of the diesel engine and simplifies service, since in future we will use the unit across our whole range of mobile harbor cranes.”
