Designed to be extremely robust, Model 7 Harbour Cranes are intended for high-performance applications and, as a consequence, very high handling rates – assured by lifting capacities of up to 140 tonnes, working radii of up to 51 m and very high hoisting speeds of up to 120 m/min. Added to this are the usual high crane classifications, such as A7 for a 57-tonne grab curve or A8 for a 50-tonne grab curve.
This technological concept makes Model 7 cranes suitable not only for universal terminals of all sizes but also – and in particular – for special purpose terminals frequented by Post-Panamax class container vessels and bulk carriers up to Capesize where high annual working volumes are achieved. Harbour Cranes such as the Model 7 series – uncompromising high-performance machines with long service lifetimes and universal characteristics – give a considerable boost to the machinery capabilities of such terminals.
Their application range includes, in particular:
- intensive, fast container handling, including Twinlift operation
- long-term, fast bulk handling with a 4-rope grab
- efficient handling of heavy project cargoes.
