Duke Tower Kitchener | 39 fl | completed

How do they do that? With no ramp, how does the dirt get into the dump trucks? Do the excavators have to load it into buckets and the crane lifts them out? For that matter, can the crane lift out the excavators or do they get them out some other way?

They can lift them out with a tower Crane but they might get smaller excavators in the hole and then that excavator does the excavation once the ramp is gone.

The current excavators look to be Cat 335's   they weigh over 84 000 lbs   an average tower crane cant lift that kind of weight.  I agree it could lift a much smaller excavator..
