Rigger certification.
1. What is meant by the term "two blocking"?
A. The load strikes the boom while swinging.
B. The load block contacts the boom point sheaves.
C. Placing blocks under the outrigger beams.
D. Stacking loads on top of one another.
ANSWER: B. The load block contacts the boom point sheaves.
RATIONALE: Two-blocking occurs when the load block contacts the boom
point sheaves. This can damage the hoist line and equipment and may create a
risk of load failure.
2. What is required if there is a deviation from the lift plan?
A. The rigger's permission
B. A new lift plan
C. Mark ups on the existing lift plan
D. The supervisor's permission
ANSWER: B. A new lift plan
RATIONALE: A deviation from the approved lift plan requires the changes to
be reviewed and addressed through a new or revised lift plan, with the required
approvals, before the lift proceeds.

,3. Lifting 20,000 lbs with a 2-leg bridle sling at a 30° horizontal sling angle,
what is the force applied to each leg?
A. 20,000 pounds
B. 40,000 pounds
C. 10,000 pounds
D. 30,000 pounds
ANSWER: A. 20,000 pounds
RATIONALE: For a symmetrical two-leg bridle sling, the tension in each leg
is the half load divided by the sine of the sling angle measured from the
horizontal: (20,000 ÷ 2) ÷ sin 30° = 10,000 ÷ 0.5 = 20,000 pounds.
4. In multiple crane lifts using an equalizer beam, the weight of the beam should
be considered:
A. A non-factor
B. Part of the crane boom
C. Part of the load weight
D. Part of the crane weight
ANSWER: C. Part of the load weight
RATIONALE: The equalizer beam and other lifting accessories contribute to
the total suspended load. Their weight must be included when calculating the
load each crane will carry to ensure the crane's rated capacity is not exceeded.
5. On level ground using skids and rollers, what percent of the weight of the
load should yield the required line pull as a general rule of thumb?
A. 2%
B. 5%
C. 10%
D. 20%
ANSWER: B. 5%
RATIONALE: As a general rule of thumb, moving a load on level ground
using skids and rollers may require a line pull of approximately 5% of the load's
weight. Actual pulling force depends on friction, roller condition, ground level,
and other factors. The required force should be assessed before moving the load.

,6. All of the following are results of unbalanced reeving of the hook block
EXCEPT:
A. Wear on the wire rope
B. Wear on the hook
C. Torque on the boom
D. Wear on the sheaves
ANSWER: B. Wear on the hook
RATIONALE: Unbalanced reeving can cause uneven loading, excessive wear
on the sheaves and wire rope, and unwanted forces or torque on the boom. Wear
on the hook is not the typical direct result identified in this question.
7. Before a spreader bar or beams can be used they MUST have been:
A. Tested and approved
B. Repainted
C. Upgraded from the previous job
D. Used before
ANSWER: A. Tested and approved
RATIONALE: Spreader bars and lifting beams must be inspected and
confirmed suitable for their intended use, with appropriate testing, certification,
and approval where required. Their rated capacity and identification markings
must be verified before use.
8. When materials are being hoisted to an upper level, a tag line is used to:
A. Help raise the load
B. Stop the process
C. Stop material from falling
D. Help control the load
ANSWER: D. Help control the load
RATIONALE: A tag line is used to help control a suspended load, guide its
movement, and reduce unwanted rotation or swinging. Personnel should remain
clear of hazardous areas and avoid placing themselves where the load could
strike or trap them.

, 9. Two cranes are lifting 100 tons. If crane A has 40% of the load, how much
weight will crane B have on its hook?
A. 240,000 lbs
B. 80,000 lbs
C. 120,000 lbs
D. 60,000 lbs
ANSWER: C. 120,000 lbs
RATIONALE: Crane A carries 40% of the total load, so crane B carries the
remaining 60%, assuming the two cranes together support the entire load. Load
on crane B = 100 tons × 60% = 60 tons. Using 2,000 pounds per US short ton:
60 × 2,000 = 120,000 lbs.
10. A rigger must lift a 16,000-pound load using a two-leg bridle sling. Both
legs are at a 60° angle from the horizontal. What is the approximate tension in
each leg?
A. 9,238 pounds
B. 4,619 pounds
C. 16,000 pounds
D. 8,000 pounds
ANSWER: A. 9,238 pounds
RATIONALE: Tension per leg = Load ÷ (2 × sin angle). Therefore, 16,000 ÷ (2
× sin 60°) = approximately 9,238 pounds per leg.
11. Before a critical lift begins, what should the rigger verify first?
A. The crane paint condition
B. The lift plan, load weight, equipment capacity, and hazards
C. The operator's preferred working speed
D. The availability of replacement tires
ANSWER: B. The lift plan, load weight, equipment capacity, and hazards
RATIONALE: A critical lift requires careful planning, verification of load
information, confirmation of equipment capacities, and assessment of hazards
before work begins.
