Ironworkers Wind Tower Erection Specialist Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• Which lift plan component ensures wind turbine components are

moved safely according to engineering specifications?

• Cost report
• Weather history log
• Rigging plan
• Training attendance sheet

Rationale: A rigging plan defines the proper slings, configurations,

and movement path for lifts.

• What is the maximum wind speed typically allowed for lifting tower

sections with a main crane?

• 20–25 mph (9–11 m/s) 1 / 3

• 35 mph (15 m/s)
• 10 mph (4 m/s)
• 50 mph (22 m/s)

Rationale: Most turbine manufacturers and lift plans prohibit major

lifts above ~20–25 mph due to load sway and control issues.

• When installing anchor bolts on the foundation, what is critical before

setting the base flange?

• Applying touch-up paint
• Verifying bolt tension and alignment
• Removing shims
• Adding grout beforehand

Rationale: Bolt integrity and correct layout must be verified to ensure

structural base stability.

4. The primary purpose of a tag line during tower section lifting is to:

• Lift heavier loads
• Control rotation and orientation
• Provide crane backup
• Measure wind

Rationale: Tag lines allow ground control to prevent spinning of

cylindrical components.

• What device is commonly used to protect slings from sharp tower

edges?

• Jack chain 2 / 3

• Edge protector / softener
• Wire rope clip
• Binder

Rationale: Sling protection prevents cutting and sling failure.

• Which method is typically used to guide upper tower sections into

alignment with lower sections?

• Glue
• Draw-in bolts / alignment pins
• Ratchet straps
• Hammering flanges

Rationale: Alignment hardware ensures precision fit-up of bolted

flanges.

• Before climbing, what must be verified regarding personal fall arrest

equipment?

• Uniform color
• Inspection of harness, lanyard, energy absorber
• Size of worker’s boots
• Number of carabiners

Rationale: Equipment inspection prevents failure during a fall event.

8. A torque wrench is used on tower flange bolts primarily to:

• Remove rust
• Apply specified tension
• Change bolt diameter
• / 3
