The crane operator takes the construction hoist (temporary elevator for material and workers) to the floor where the base of the crane is accessible and then climbs up the interior of the crane tower. The crane tower will have either a ladder with a cage or a very steep stairway within it.When tall buildings such as this are being built, how in the world does the crane operator gain access to the cab?!! That thing is pretty high in the air!!! Holy moly!!!
