how to compute the allowable load that a cable connected to a crane can carry?

I want to compute the allowable load that a cable crane can carry. Is there a sample problems that someone can refer to me as a reference for my computation. I just want to know if a 500kg weight, can the cable or tension rod connected to the crane carry this load?

    unless you are in school the best method is to call the crane manufacturer and ask what formula they used to dertermine the load for the crane to be able to lift.

    If you are doing a problem in a text book, you might need to look for more information like the strength of the cable (equilibrium) or the lenth and strength of the arm (for torque).

    If you are just looking for general information it will be a good idea to start looking at spec sheets from manufacturers, there are a couple of factors and others I do not include here, like the height that you might need to lift this weight and then the horizontal displacement that would need to take place if any.

    Your solution might range from a simple arm with a winch to a really big monster that will carry your 500kg for quite some distance while lifting it really high.
