Eerecting and dismantling are key functions of typical construction cranes.
If you build a permanent crane for 30 year operation for most weather conditions it can be heavier and made of larger and heavier body segments. More like cranes in harbors.
I think the counterweights can be removed if you have symmetric working arms lifting exactly the same weight at the same time.
