One thing I am puzzled about is why SpaceX chose to purchase an expensive LR 11350 for moving stuff around the launch pad, rather than a much cheaper tower crane mounted on top of the Launch Tower. Similarly it seems to be that a lot of the movements of equipment and supplies around the construction site could be performed more easily with a tower crane than the various mobile cranes.
I'm still not sure why they opted to buy, rather than just renting a crane tho
frankencrane was an LR11350 ( 1350 T max lift), the new crane is an LR11000 (1000 T Max lift)Leibherr crane numbers are a "1" plus the lift capacity in metric tons

So by using Stage Zero, SpaceX saves the purchase price of a $10 million crane.
There are also lead times: Liebherr don't just keep a stock of ready-made ultralarge cranes to hand for immediate fulfilment, they're built to order. SpaceX are not ones to sit on their laurels whilst waiting for shipping, hence renting one in the meantime. SpaceX do in fact have a tower crane (well, technically a column crane) on site. It's been sitting in the shed next to the 'roll lift park' since before even the Stargate building was finished. I'm starting to think they've actually forgotten that it's there.
