that is as full "fledged"of a crane as any, the cab is on the opposite side that picture is taken from. the tower height of that crane is low, as there is no building above grade. as i understand it, the entire call center is below grade and there will be park above it.
that particular crane has done several 20+ story jobs in calgary, also that particular model of crane has done many of the 12 story+ buildings in calgary over the last ten years.
that crane is erected on a static base and uses ballast weights instead of a foundation to "balance" out the top of the crane. that base is also designed to be used as a "traveler" it uses a set of wheels known as bogies and is set on rails to travel long lengths on a site. as an example the city water center office had the same make/crane with a traveling base.
the small tower cranes that are operated by remote control are know as self erect cranes. the main differences is that self erect cranes can be erected with out the assistance of another crane. they also swing from the bottom, the slew bearing or turntable is located at the bottom of crane along with its counter weight which also acts as ballast weight. these cranes are not secured to the ground they have outriggers similar to a mobile crane.
theyare small but can have jib lengths of 150 feet and hook heights of about the same, with very limited lifting capacities.

That crane doesn't seem to have a cab on it. Is it operated from the ground? Does it qualify for the list? I'm no expert, but it doesn't seem to be a full fledged tower crane.
