A data campus doesn't earn a dollar until it's energized, and it can't be energized until the heavy electrical and mechanical gear is landed: main power transformers, backup generator fleets, chillers, switchgear, and increasingly whole prefabricated e-houses and power skids dropped in as units. Every one of those is a crane pick, and every one of them sits on the critical path to first megawatt.

On a schedule measured in weeks-to-power, the crane isn't a trade you call when you're ready - it's the pace-setter for the whole campus. A rented machine stuck in a hot-market queue doesn't just cost a lift; it moves the energization date.
