NCCCO Service Truck Crane case studies
NCCCO Service Truck Crane · Put your knowledge to work in context.
The CCO Service Truck Crane Operator certification (STC) is a subcategory of the Telescopic Boom-Fixed Cab (TSS) certification, built for operators of smaller truck-mounted telescopic cranes that are typically run by radio remote or pendant control. These machines generally have shorter booms and lower capacities than other fixed-cab cranes. The NCCCO Service Truck Crane case studies are 5 cases and about 2,321 words.
