There's about five centuries in there between the renaissance and steel-framed buildings!
But of course cranes existed (on building sites, and in factories) since approximately the day after we invented the rope. But an elevator safe and reliable enough to make rich people buy an apartment above the 2nd floor? And cities dense enough that they were tempted to do so? Those took longer.
