Watching the awful tragedy caused by the earthquakes in Turkey, and in general, the biggest problem is obviously removing the rubble to rescue people, why do they not install a crane (2+ days) and use mobile ones in the meantime?
The OP may be thinking of “cranes” with claws, like those used in scrapyards. If so, that’s a very specialized piece of equipment and there aren’t very many of them. Most cranes are for construction, and designed to lift large solid items, not a heap of loose material.
