    Have wandered about this for a while now but i can't seem to find a simple answer.

    Sooo, on a crane, how do the get those massive, heavy, concrete blocks up there to counterbalance the crane?.

    Is is another crane, a mobile one? - That to me seems the easiest way..but how?

    Keep it simple please folks

    The crane lifts up each counter weight and attach's it by itself. The crane can lift one counterweight at a time easily because it weighs allot more than only counterweight does.

    I watched it all.
    Not sure if it answered the question or not.
    The top part of the crane looked locked in place to me.
    It did seem interesting enough to watch the whole 90 seconds required.

    Year ago I asked another crane question but I don't think anyone could answer it.

    If you notice there is a new type of crane that doesn't have the counterweight at the top. So I wondered why would you have the weight at the top? It seems a very difficult way of using a crane. But I don't think anyone had the answer

    Aaargh! Is it only 90 seconds?
    I'm at the end of my monthly download allowance so I didn't dare do more than wait for it to start... just in case I ran out of time altogether. I'll watch it tomorrow (with a critical eye).

    It seems to just be building the tower structure, I don't see the counterbalance being added to.

    The counterweight is lifted in place by anohter crane when the tower of the crane is still close to the ground. Then if the crane is a "climber" it takes it up with it. Most tower cranes are jumped up in "lifts" a few stories at a time as the building goes up. The crane tower is secured to the building ever 3 or 4 floors for highrise building. In smaller buildings, the crane can be a free standing cantilever off the base but is put up in sections by another crane.
