In New York City, there are five truckloads like this parked on the street. Any idea what they’re used for (obviously some kind of construction, maybe under the street, but would to know exactly how they’re used)? Thanks!

A Long Reach Excavator, a variant of a normal Excavator, is a normal Excavator, but with a longer arm. This one is the CAT 395's Long Reach Variant, with a long reach of 28 meters. (About 1102 inches or almost 92 feet in American Units.)

(CAT themselves said that the arm was 28 meters long, so I'll trust them.)

...but there exists a variant of this kind of Excavator with an EVEN LONGER ARM! UHDs, or Ultra High Reach Demolition Excavators, have an even longer and slightly more articulated arm designed specifically for demolishing tall buildings. Remember: All UHDs are Long Reach Excavators, but not all Long Reach Excavators are UHDs.

So if the Nova Scotia dollars are drying up, you might want to consider a few new sponsors for the show.
