Gears, metal plates - it all looks quite solid. Lets say the building stands after the pole shift, having been retrofitted and braced, and the machinery itself is pretty durable. There are factors in this scenario that are not being considered. All the necessary small parts, the lubricants and additives, that will not be available.
Most lubricants are necessary, to maintain a certain chemical balance, or there is corrosion.
Without these lubricants, parts burn out, wear out, and you can't simply pour water or any chemical in, you need a particular chemical. The chemical industry will be very hard hit, as much of their stores are liquid and will burst, spray, disburse, and require specialized ingredients to create in the first place. So you back up, endlessly, and anytime there is a break in the link, the link is broken and affects everything downstream. So it all goes down the chain. Even a tiny broken part can stop the process, as perhaps a particular metal or particular alloy is needed.
