You can cut the concrete, too, for that matter, with oxyacetylene, as long as 
you wear certain protective gear.  We have a few vault covers here that are 
concrete covering the largest vaults we have.  You need more than a manhole 
hook to get one of those covers up.  

And when you think you have it safely burried someone
drives a tunnel boring machine through it -
