Could anyone tell me how they erect a construction crane.Some how they just are suddenly THERE, as If by magic.It seems as though the Boom part of the crane must be kind of JACKED up into place.That is the only way I can see them getting those GIANT concrete blocks into the back end of the boom. It doesn't seem possible otherwise. The only other thing I can thing of is the bulk of the pieces are brought in by helicoper and attached.Everything kind of makes sence except the Giant concrete blocks used as a counter weight. ALSO, if the blocks are needed to act as counterweigth to the CRANE itself..why doesn't the Crane fall over when it picks stuff up???
How do they erect the construction cranes? Not very well according to the news of them toppling down of late. Seriously, the cranes are lifted upward one or two floors at a time as the building progresses upward - this is usually accomplished by pulling them up into place with heavy cables and powered winches.
