What the Course Entails and Exam Details

The intermediate rigging course and exam cover a deep and broad range of topics to ensure you can manage lifting scenarios that are inherently more dangerous.

This intermediate certification doesn't just ask "how to tie a knot," but "which complex hitch to use for this specific load shape, weight distribution, and environmental constraint."

Key skill areas include:

• Advanced Load Calculations: Precise determination of load weight, center of gravity, sling tension, and hardware stress for irregular and multiple-point loads.

• Complex Rigging Configurations: Understanding and application of specialized rigging, including equalizer beams, spreader bars, tandem crane lifts, and complex basket and bridle hitches.

• Load Chart Interpretation: Expert-level knowledge of interpreting crane load charts, applying all necessary derating factors for dynamic forces, and determining the crane’s true capacity.

• Hazard Control & Pre-Lift Planning: Creating and implementing comprehensive lift plans, conducting pre-lift hazard assessments (SWMS), and understanding the Hierarchy of Hazard Control.

• Equipment Inspection & Application: Detailed knowledge of inspection criteria for all rigging hardware, slings, and below-the-hook lifting devices, including criteria for rejection.

The exam itself typically includes a theory component consisting of approximately 75 multiple-choice questions, which tests your theoretical understanding of these concepts. Candidates must also complete a practical skills assessment to demonstrate their proficiency in a real-world setting.

What to Expect in the Final Exam

Knowing what to expect on exam day is key to reducing anxiety and ensuring focus.

The theoretical portion of the ADC Intermediate Rigging Exam is most often delivered via a multiple-choice format, designed to challenge your problem-solving abilities rather than simple recall.

• Theory Format: Approx. 75 Multiple-Choice Questions.

• Practical Component: Hands-On Skills Assessment (separate registration and execution).

• Time Limit: Usually 150 minutes for the theory exam.

• Passing Score: A minimum score of 60% is typically required.

Candidates can expect questions that provide complex rigging scenarios and ask them to choose the correct load calculation, select the appropriate equipment, or identify a violation in a lift plan based on standard safety regulations.

How to Study and Exam Centers

Effective study is focused, practical, and systematic.

To excel in the ADC Intermediate Rigging Exam, you must blend theoretical study with continuous practical application.

Here is a recommended study strategy:

1. Utilize Official Resources: Use textbooks, online courses, and consensus standards from authorized training providers.

2. Practice Load Calculations Regularly: Work through problems repeatedly until you can flawlessly calculate weight distribution and sling stress under pressure.

3. Use Practice Exams: Take timed practice exams to simulate the pressure and format of the actual test, identifying your weaknesses.

4. Review Core Regulations: Deepen your understanding of specific OSHA and ASME standards related to intermediate rigging practices.

5. Hands-On Practice: Apply your theoretical knowledge on real worksites or during practical training sessions.

When you are ready to take the final exam, it is typically administered through a network of authorized training providers and certified test centers.

These physical testing centers ensure a controlled and fair examination environment, especially for the practical skills assessment.
