Digger Derrick Certification Prep Modules
Six lessons that follow a pole-setting job from the yard to the final tamp.
Digger derrick anatomy
Telescopic boom, auger drive, pole guide (pole claw), winch line, outriggers and the controls at the platform or pedestal.
Utility-sector regulations
How OSHA's crane rule treats digger derricks, when the utility exemption applies, and the electric power standards in Subpart V and 1910.269 that take over.
Setup & stabilization
Positioning on road shoulders and soft right-of-way, outrigger pads, leveling and the limits of working on a grade.
Auger & pole operations
Drilling technique in different soils, auger torque reactions, picking poles at their balance point and walking them into the hole safely.
Load charts & capacity
Reading capacity with the pole guide and winch, deductions for attachments, and how boom angle changes what the truck can handle.
Certification exam prep
Practice questions modeled on the written exams, plus a review of tasks commonly scored on the practical.
Who This Utility Course Serves
- Journeyman and apprentice lineworkers
- Telecom pole crews
- Electric co-op field crews
- Utility contractors and storm crews
- Municipal power departments
- Fleet and safety trainers
Exemption or not, prepare properly
Our course prepares you for the knowledge test only. A recognized credential comes from NCCCO or NCCER after official written and practical exams. Compare them on the NCCCO digger derrick overview and the NCCER digger derrick overview.
Study Habits That Work for Line Crews
Utility schedules are unpredictable. A week of routine maintenance can turn into ten days of storm restoration overnight, so the course is broken into short lessons you can finish in a truck cab or during a lunch break.
We suggest working through the regulations module early, while you're fresh, because the exemption rules are where most candidates lose points. Then alternate chart practice with auger and pole lessons so the math stays tied to real tasks.
Before you schedule the written test, complete the full practice set in one sitting to build stamina. Most line crews already know the machine well; the exam simply asks them to explain why they do what they do.
When OSHA's Crane Rule Applies to a Digger Derrick
This is the single most misunderstood topic for utility crews. Treat this as a summary and confirm the specifics with OSHA's Subpart CC scope and your employer.
| Activity | Typical treatment |
|---|---|
| Augering holes for electric or telecom poles | Generally excluded from Subpart CC |
| Setting, removing or retrieving utility poles | Generally excluded from Subpart CC |
| Handling materials installed on those poles | Generally excluded from Subpart CC |
| Lifting other construction materials, such as setting a transformer pad or trusses | Can fall under Subpart CC — certification expected |
What You'll Be Able to Do
Work smarter after storms
Recognize the extra risks of damaged poles, tangled conductors and saturated ground when crews are tired and rushed.
Handle poles under control
Plan the pick, use the pole guide correctly and keep everyone clear of a pole that can roll or swing.
Defend your chart reading
Explain why a pick is or isn't within capacity — the same reasoning examiners ask for.
