Port Crane Operator Certification Exam Practice Test Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary purpose of a crane load chart?
- To determine fuel consumption
- To estimate operator skill level
- To show the crane’s lifting capacities at various configurations
- To calculate wind speed requirements
Rationale: Load charts specify lifting capacities based on radius, boom
angle, and configuration.
- Which factor most reduces crane lifting capacity?
- Cold weather
- Increased load radius
- Bright sunlight 1 / 3
- Operator location
Rationale: As load radius increases, leverage decreases, reducing capacity.
3. The anti-two-block device prevents:
- Boom collapse
- Hook rotation
- The hook block from contacting the boom tip
- Counterweight overload
Rationale: A2B systems stop unsafe hoist travel to avoid collisions.
4. When preparing a crane for operation, the first step is to:
- Extend the boom fully
- Perform a pre-operation inspection
- Hoist the hook high
- Test swing at maximum speed
Rationale: Inspections ensure equipment is safe before any movement.
5. The signal person must:
- Be certified in rigging only
- Be qualified to give standardized signals
- Stand directly under the load
- Avoid all radio use
Rationale: Only trained individuals may provide crane communication
signals.
- Wind speed becomes a concern for most port cranes at: 2 / 3
- 10 mph
- 15 mph
- 20–30 mph depending on crane type
- 50 mph
Rationale: Many cranes derate or shut down around 20–30 mph for safety.
7. Outriggers must always be:
- Extended halfway
- Not used on hard ground
- Extended only when wind is high
- Fully extended and leveled per manufacturer instructions
Rationale: Full extension and leveling ensure crane stability.
8. A load should be lifted:
- As fast as possible
- With the boom angled over 70 degrees only
- Vertically to avoid side loading
- While slewing simultaneously
Rationale: Side loading can destabilize cranes and damage booms.
9. A dynamic load refers to:
- A load not yet weighed
- A load submerged in water
- A load in motion
