The scope includes only cranes of the types described in para. 22-0.2.1, articulated by hydraulic cylinders, which are powered by internal combustion engines or electric motors and are mounted on a mobile chassis or stationary installation. Frequently, articulating cranes are equipped with a load hoist mechanism to broaden their versatility. Load hoist mechanisms equipped machines are covered by this Volume.
