Like anything theses days, marketing names change over time or to stand out and be different.
Excavators were at one time just excavators that was arrived from something else. As the needs for other needs of equipment's for site rose, the excavator change from one type of work it could do, to a number of different roles it does today. Adding a jackhammer along with other attachments was chosen to cut down on the cost of having X equipment sitting around and doing nothing. As other companies enter the equipment manufacturing field, some chose different names from what I see today, yet do the same job.
Since this not my field of work, don't follow the equipment name changes and X company dose use drill in place of jackhammer that I read about after my last posting.
The Edge Towers has an excavators that does 3 different operations that I have seen so far, that it was jackhammer on May 21 and a true excavator. on the 22nd when I shot the site.
Some equipment that can do different role still remain a single operation only, since they are in demand more than other type of equipment.
Small contractors will us equipment that can handle different operation since they lack yard space and capital to maintain a large fleet.
Looking at a drill that is really a jackhammer from on line info is miss leading in sense, but that marketing for you.
