The above video is of a bunch of massive cranes to lift each other. Cool It’s “the most powerful crawler crane in the world of conventional design”, capable of lifting up to 3,000 tonnes at 12 meters. In the video however, the presenter says it’s got a capacity of 1,521 tonnes. This discrepancy in lifting capacity is probably due to the fact that it’s lifting further away than 12 meters in this particular setting. All the other cranes combine to a weight of roughly 1,430 tonnes, so it’s working at 94% capacity.
