Crane operator test questions and answers pdf

These sample questions are intended to convey something of the style and content of the National Operator Certification Program examination developed and administered by the National Commission for the Certification of Crane Operators.

They are not actual test questions, nor do they attempt to address all of the areas of knowledge tested on the CCO certification examination. Response to these questions is not necessarily an indication of performance on the CCO examinations.

What action does a signal person intend the operator to perform if he extends his arm at shoulder height, makes a fist with his hand, and sticks his thumb up?

1. Boom down

The load line of the crane you’re operating comes into contact with an energized power line. There’s no sign of any other danger, such as fire. In such a situation, you should:

1. Climb down carefully from the crane cab
2. Jump down, feet together
3. Stay in the cab until the lines are de-energized
4. Get as far away from the crane as possible

Unless the manufacturer states otherwise, the net capacity of a crane on main boom is the capacity listed in the load chart:

1. minus the weight of the rigging and all attachments
2. plus the weight of the rigging and all attachments
3. minus the weight of the rigging and all attachments not in use
4. minus the weight of the rigging alone

Unless the operator takes account of boom deflection, when lifted off the ground, a properly rigged load may:

1. swing out away from the crane
2. swing in towards the crane
3. raise absolutely vertically
4. shift in its rigging

NCCCO test questions and answers

While there are other companies seeking to certify crane operators, only one organization, the National Commission for the Certification of Crane Operators (NCCCO), provides CCO certification.

Tips for Passing the NCCCO Exams

Take a preparatory class. Training is the key to passing. You may think you know everything about cranes, but how well do you know OSHA and ANSI/ASME rules, regulations and industry best practices? A preparatory class builds confidence so you won’t be intimidated by the test.

Read the Candidate Handbook. The manuals tell you everything you need to know about the NCCCO exams, from start to finish. Focus on the outline of the written exams, the outline is like the “blueprint” for the exams.

Forget how you do it daily. You may be doing it safely, but are you following the rules, manufacturer recommendations, and industry best practices? Come to class with an open mind. In fact, you may learn something you didn’t know before.

Exams require experience. The Candidate Handbook states: “CCO certification exams are designed for operators who are trained and currently working in crane operations.” If you are inexperienced, you will need extensive training to get to that level. You can’t get lucky on this test.

Study the load tables. One of the most important parts of this test is being able to solve a load graph problem. If you take a CCO Prep training class, you will be provided with a sample problems and loading diagrams.
