Safety & Roles
Crane Operation Fundamentals & Roles
The crane team, the operator's authority to stop, and pre-operation responsibilities.
The Lift Team
A safe lift involves several roles: • OPERATOR — runs the crane and is responsible for safe operation. • SIGNALPERSON — directs the operator when the load or path isn't in full view. • RIGGER — selects and attaches the rigging to the load. • LIFT DIRECTOR — oversees the overall lift.
The operator must understand and respond to standard hand signals and can take signals from only ONE designated signalperson at a time — except a STOP signal, which the operator must obey from anyone.
Stop Authority
The operator has the authority and the DUTY to stop and refuse to handle loads when there is a safety concern. If conditions are unsafe (high wind, unstable ground, an improper lift), the operator stops.
A STOP signal must be obeyed no matter who gives it. Never operate a crane you believe to be unsafe.
Pre-Operation Inspection
Before each shift, conduct a documented inspection: wire rope/hooks, controls, brakes, hydraulics, safety devices, tires/tracks, and outriggers. Check for the load chart and that all guards are in place.
Annual and frequent inspections are also required. Tag out and remove from service any crane with a defect affecting safe operation.
📖 Key Terms

💡 Exam Tips
- ▸A STOP signal must be obeyed from anyone — not just the designated signalperson.
- ▸The operator may take operating signals from only one signalperson at a time.
- ▸The operator has the duty to stop an unsafe lift.
- ▸Inspect the crane before each shift and document it.
