As I remember it, the cable was dropped to the planet from the
spaceship, like a gigantic sling. I'll check this out.

In another book dealing with similar systems [Can I remember the
name.. nope :-( ] , Clarke has a small probe drop from geosynch orbit
to Sri Lanka, after which heavier ribbons were dropped and attached
to a mountain top, after which the orbiting station "extruded" the
tower towards the ground!

{spoiler follows}

 In fact a cable car gets jammed on the way up, and has to wait for
the tower to grow down to it!
