You should have seen some of the monsters cranes around when we first built the Worsely plant in the early 80's.....1000+ tonne lifting capacity. The biggest land crane I ever saw was on the burrup (karratha) being the gotwald which could lift 2500 tonne when mounted to a concrete ring. Funny thing was it got to the burrup a bit early with its 3 crane drivers, 6 semis full of spares and 12 full time riggers and spent the first week lifting scaffold planks (20kg) one by one

. Not to worry though it only cost $1800 an hour back then
