Who Needs Service Truck Crane Certification
NCCCO built the STC credential for industries that rely on small telescopic cranes: HVAC, sign installation, telecommunications, utility installation and maintenance, tree service and building supply. These cranes are usually run from a remote or pendant control rather than a cab.
OSHA's construction rule covers cranes with a rated capacity over 2,000 pounds used in construction. If your service truck crane hoists a rooftop unit onto curbs, sets a sign or places materials that become part of a structure, the operator needs accredited certification under 1926.1427. A pure delivery — setting material on the ground without arranging or installing it — is generally outside the rule.
That dividing line is why so many service fleets certify their drivers: the same truck may do an exempt delivery in the morning and a covered install in the afternoon.
STC vs. TSS: Which Credential Fits
| Question | Service Truck Crane (STC) | Telescopic Fixed Cab (TSS) |
|---|---|---|
| Equipment | Service truck cranes only | Boom trucks and other fixed-cab telescopic cranes |
| Covers the other? | No — STC does not qualify you for TSS cranes | Yes — TSS holders also receive STC |
| Written testing | Single STC written exam | Mobile Core exam plus TSS specialty |
| Best for | Operators who will only run service truck cranes | Operators who may move up to larger fixed-cab cranes |
What the STC Written Exam Covers
Our service truck crane training is built around these domains.
Site setup: truck positioning, outriggers and work zone control
Operations, including remote and pendant control use
Technical knowledge of booms, winches and safety devices
Reading the manufacturer's load chart and capacity limits
Power line clearance and overhead hazards on service calls
Which tasks are construction under Subpart CC and which aren't
Preparing Without Pulling Trucks Off the Road
Service fleets can’t easily spare drivers for classroom days. The online STC course lets each technician study between calls and finish at their own pace, with a certificate of completion for the company file. Schedule the hands-on practical once the written is passed — and give each operator some supervised practice with the remote control on a comparable crane before test day.
