Is it possible to animate wire ropes?

I have a 3DVIA Composer animation in which I am trying to show the animation of wire ropes in a winching system.  The SW file that I loaded from shows the wire ropes in the "up" position - their shortest length.  Is there a way that I can show the wire ropes lowering the hook?  I can't figure out how to stretch the wire ropes in the animation.

Thanks,

Heather
