The scope includes only cranes of the types described in para. 220.2.1 that are articulated by hydraulic cylinders and powered by internal combustion engines or electric motors and that are mounted on a vehicle or stationary installation. Articulating cranes equipped with a load hoist mechanism to broaden their versatility are covered by this Volume. Some basic machine types within this scope are convertible for excavating work and other uses not considered to be lifting service. The requirements of this Volume are applicable only to such machines when used as lifting cranes. When cranes within the scope of this Volume are used for service other than lifting service, the manufacturer or (when not available from the manufacturer) a qualified person shall establish the ratings, operating limitations, maintenance, testing, and inspection requirements that apply during that use.
