NCCCO Articulating Crane case studies
NCCCO Articulating Crane · Put your knowledge to work in context.
The NCCCO Articulating Crane credential is a certification for operators of articulating boom cranes - machines with a knuckle-boom that folds rather than telescopes. It is aimed at operators who load and unload materials, run grapples or buckets, and work in construction, utilities, and delivery yards where the crane is mounted on a truck or trailer. The certification process is administered by the National Commission for the Certification of Crane Operators, a nonprofit founded in 1995 and described by the organization as committed to quality, integrity, and fairness in testing since then. The exam is built around five domains, each weighted at 20 percent: site and equipment inspection and setup; load charts and capacity determination; rigging and load handling; operations and signaling; and safety, standards, and regulations. The NCCCO Articulating Crane case studies are 5 cases and about 2,815 words.
