What is the largest crane ashore?
The largest ashore crane is the “MSG-50” that Mammoet designed and built to their own needs and ideas. It is a “ringer crane”. This is a crane that runs on a circular rolling or rail track (in this case with a radius of 30 m (~100 ft)) to both operate and slew. The ring creates a larger supporting base and better conditions for the main and derrick mast in relation to the supporting base. The crane has a maximum lifting capacity of 3,070 metric tons (3,384 sht), but the main disadvantage is that it cannot move once it is rigged. (Theoretically both MSG-50s could be combined to create an even larger crane). The Mammoet PTC (Platform Twinring, Containerised) is also an amazing crane. Designed and built by Mammoet it is also a ringer with a maximum lifting capacity of 1,600 metric tons (~1,750 sht). The remarkable thing about this crane is that when it is de-rigged for transportation, every part fits into either a 20ft- or 40ft-container, so can be easily transported worldwide.
