Sample 1

What determines which load-chart capacity applies to a lift?

  1. The actual crane configuration, boom or jib setup, radius, and chart notes
  2. The operator's preferred hoisting speed
  3. The load's appearance without a verified weight
  4. A capacity from a different crane model

Answer: A. Load-chart capacity is configuration-specific and must match the actual setup and operating radius.

Sample 2

What should happen when the operator does not understand a signal?

  1. Assume the signal means hoist
  2. Stop crane movement until communication is clear
  3. Continue slowly in the last signaled direction
  4. Let the rigger move the load by hand

Answer: B. Unclear communication requires stopping until the signal and intended movement are resolved.

Sample 3

Which condition should stop a crane lift until it is controlled?

  1. A verified load weight
  2. A level setup within chart limits
  3. Unclear signals or an unsafe site condition
  4. A clearly understood signal

Answer: C. Crane operations should stop when communication or site conditions are unsafe.

Sample 4

What is included in gross load for a crane-capacity decision?

  1. Only the object's advertised shipping weight
  2. Only the hook block and hoist line
  3. Rated capacity before required deductions
  4. The lifted object plus rigging and other load carried by the crane

Answer: D. Gross load includes the object and all rigging or attachments carried by the crane.

Sample 5

Why are hand signals studied?

  1. They support communication during lifting operations
  2. They replace all rigging inspections
  3. They are used only in offices
  4. They guarantee certification

Answer: A. Clear communication is critical around lifting operations.

Sample 6

What can happen when the hook is not positioned over the load's center of gravity before hoisting?

  1. The sling legs carry no tension until the load is fully airborne
  2. The load can tilt, shift, or swing as its center of gravity moves beneath the hook
  3. The load's weight and sling tensions automatically decrease
  4. The crane's rated capacity automatically increases because an off-center hookup reduces the effective operating radius shown on the chart

Answer: B. A suspended load seeks equilibrium with its center of gravity below the hook, so an off-center hookup can create uncontrolled movement.

Sample 7

Why are operational aids checked during crane operation?

  1. They permit continued operation after an unresolved malfunction
  2. They replace the operator's duty to use the load chart
  3. They can warn of or help control unsafe operating conditions
  4. They guarantee capacity regardless of crane configuration

Answer: C. Operational aids support safe operation, but they do not replace the operator's responsibility or the load chart.

Sample 8

Which answer best describes a signalperson's role?

  1. Authorize capacity above the applicable load chart
  2. Control the crane directly whenever visibility is limited
  3. Replace the operator's responsibility for safe operation
  4. Help communicate movement directions when needed

Answer: D. Signalpersons support communication and coordination during lifting operations.

Sample 9

What can create dynamic loading during a lift?

  1. Sudden starts, stops, or shock loading
  2. A correctly leveled crane
  3. A clear hand signal
  4. A verified rigging tag

Answer: A. Sudden movement can increase forces beyond the static load.

Sample 10

Which factor can affect crane capacity?

  1. The operator's preferred hoisting speed
  2. Configuration and operating conditions
  3. The color used to mark the lift area
  4. The order in which rigging tags are read

Answer: B. Capacity depends on crane configuration, load, radius, and conditions.
