Practice 2

1.5 hours

Learning Objectives

  • •Apply safe-operation and inspection knowledge to exam-style questions
  • •Reinforce signaling rules and OSHA crane requirements
  • •Confirm overall readiness across all four modules
  • •Build a final review plan targeting any remaining weak areas

Topics Covered

  • •Mixed review: site setup, load charts, and the radius–capacity relationship
  • •Mixed review: power line clearance and danger-zone control
  • •Mixed review: daily inspection and defect handling
  • •Mixed review: SAE J1307 signals, lost-signal and conflicting-signal rules
  • •Mixed review: OSHA 1926 Subpart CC duties and inspection schedule
  • •Final readiness self-assessment and targeted review planning

Self-Check Questions

Question 1: You are lifting near an energized overhead power line and cannot maintain the required minimum clearance. The correct action is to:

  1. A. Move faster so the boom is exposed only briefly
  2. B. Stop and have the line de-energized or relocated, or move the work, before continuing(correct)
  3. C. Continue if the load is non-conductive
  4. D. Lower the boom and proceed underneath the line
Show Explanation

Explanation:

If you cannot keep the required clearance, the lift cannot proceed safely. The line must be de-energized and grounded, relocated, or the work moved — power line contact is a leading cause of crane fatalities.

Question 2: Mid-lift you lose sight of your signaler. What do you do?

  1. A. Continue at reduced speed
  2. B. Stop all crane movement until visual contact or agreed communication is restored(correct)
  3. C. Have any nearby worker relay signals
  4. D. Set the load down wherever the boom currently points
Show Explanation

Explanation:

Loss of visual contact with the signaler requires an immediate stop. A signaler who cannot see the load cannot safely direct it, and casual relays introduce dangerous errors.

Question 3: During your daily inspection you find a structural crack near the knuckle joint. You should:

  1. A. Finish the day's lifts, then report it
  2. B. Tag the crane out of service until it is repaired and re-inspected by qualified personnel(correct)
  3. C. Weld it yourself and keep working
  4. D. Lift only light loads for the rest of the shift
Show Explanation

Explanation:

A crack in a load-bearing member can fail without warning. The crane must be removed from service and not used until properly repaired and re-inspected.

Question 4: As the working radius increases, an articulating crane's rated capacity:

  1. A. Increases
  2. B. Decreases(correct)
  3. C. Stays the same
  4. D. No longer matters
Show Explanation

Explanation:

Capacity decreases as radius increases because the load exerts more tipping leverage farther from the crane. Always read the load chart for the actual radius of the lift.

Question 5: Under OSHA Subpart CC, crane inspections are required:

  1. A. Once at purchase only
  2. B. Each shift, monthly, and annually(correct)
  3. C. Annually only
  4. D. Only after an accident
Show Explanation

Explanation:

Subpart CC requires layered inspections: a shift inspection, a monthly inspection, and a comprehensive annual inspection, each performed by appropriately qualified persons.

Question 6: An approved signaler directs a lift the operator can see would overload the crane. The operator should:

  1. A. Always follow the signaler without question
  2. B. Refuse the unsafe lift — the operator may always decline an unsafe signal(correct)
  3. C. Perform the lift and document the signaler's name
  4. D. Perform the lift at reduced speed
Show Explanation

Explanation:

The operator is the final safeguard. Even when directed by an approved signaler, the operator may and must refuse any signal or lift that would be unsafe.

Question 7: Before driving a loader crane truck on the road after a lift, the operator must:

  1. A. Leave the boom up to save time at the next stop
  2. B. Fully stow the boom, retract and secure the stabilizers, and apply transport locks(correct)
  3. C. Retract only the stabilizers
  4. D. Do nothing — it is road-ready once the load is down
Show Explanation

Explanation:

Traveling with the boom raised or stabilizers extended is unstable and endangers traffic and structures. The crane must be fully stowed and locked for transport before the truck moves.
