NCCCO Service Truck Crane study guide
NCCCO Service Truck Crane · Work through your exam, one topic at a time.
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 credential applies only to service truck cranes; an operator who needs qualification across all telescopic boom fixed-cab cranes must earn the full TSS certification instead. Certification requires passing both a written and a practical exam and remains valid for five years. The NCCCO Service Truck Crane study guide has 4 sections and about 1,272 words.
01Site: Ground, Setup, and Hazard Control
The Site domain tests whether you can choose and prepare a position before the boom goes up: ground bearing, leveling, overhead and underground hazards, access, and public protection. A service truck crane is usually set on outriggers, so the ground under the floats-not the tires-carries the load.
359 words, about 2 min02Operations: Pre-Lift, Lift Execution, and Shutdown
The Operations domain covers the lift from pre-operation inspection through shutdown: functional checks, communication, load control, and securing the machine. Walk around the crane: hydraulic leaks, tire condition, outrigger beams and pads, wire rope, hook latch, boom wear pads, LMI, and anti-two-block.
325 words, about 2 min03Technical Knowledge: Capacity Limits, Components, and Inspection
Technical Knowledge tests the machine itself: how capacity is limited, how components fail, and what inspections and safety devices are required. A service truck crane is rated by structure (boom, cylinders, wire rope) and stability (tipping).
284 words, about 1 min04Manufacturers' Load Charts: Configuration, Radius, and Deductions
The Load Charts domain tests whether you can find the correct capacity for the actual machine configuration and subtract everything hanging below the boom. Capacity depends on outrigger configuration, boom length, boom angle/radius, quadrant (over front, side, or rear), jib stowed or deployed, counterweight, and attachments.
