1. A rigging supervisor on a large commercial construction project in
Maryland is assigned responsibility for overseeing the lifting of
prefabricated concrete wall panels using a lattice-boom crawler crane.
Before the lift begins, the supervisor reviews the rigging plan and
notices that the center of gravity of one panel is offset because
embedded mechanical conduit was added after fabrication. Which
action should the rigging supervisor take FIRST to ensure compliance
with safe rigging practices and prevent uncontrolled load movement
during the lift?
A. Proceed with the lift while increasing crane boom angle to compensate
for the offset weight
B. Direct workers to manually stabilize the panel with tag lines only after the
load leaves the ground
C. Recalculate sling tensions and rigging configuration based on the revised
center of gravity before authorizing the lift
D. Reduce the lifting speed of the crane operator to prevent dynamic
loading effects
C. Recalculate sling tensions and rigging configuration based on the revised
center of gravity before authorizing the lift
,A rigging supervisor must verify that the rigging arrangement matches the
actual load characteristics before lifting operations begin. An altered
center of gravity can create unequal sling loading, load rotation, and
instability, making recalculation and redesign of the rigging configuration
the most critical first step.
2. During a steel erection project, a rigging supervisor observes workers
using alloy steel chain slings that have stretched links and illegible
identification tags. The workers insist the slings were used earlier in
the week without problems. What is the most appropriate supervisory
response?
A. Permit temporary use if the slings pass a visual load test during the first
lift
B. Remove the slings from service immediately until they are properly
inspected and identified
C. Allow use only for loads below 50 percent of the sling’s estimated
capacity
D. Continue operations while requesting replacement slings for the
following shift
B. Remove the slings from service immediately until they are properly
inspected and identified
Chain slings with stretched links or missing identification tags must be
removed from service because their rated capacity and structural integrity
can no longer be verified. Supervisors are responsible for ensuring
defective rigging equipment is not used under any circumstances.
3. A rigging supervisor is coordinating a tandem lift involving two mobile
cranes lifting a large air handling unit onto a hospital roof. Which
factor presents the GREATEST operational concern requiring detailed
engineering review before the lift is approved?
A. The color coding system used for sling inspection records
B. The simultaneous distribution and transfer of load weight between both
,cranes during movement
C. The total number of workers assigned to the lift zone
D. The duration of the operator pre-shift inspection process
B. The simultaneous distribution and transfer of load weight between both
cranes during movement
Tandem lifts are especially hazardous because load weight may shift
unpredictably between cranes during movement. Engineering analysis and
coordinated lift planning are required to prevent overloading, boom
instability, and loss of load control.
4. A rigging supervisor is evaluating whether synthetic web slings may be
used to lift painted stainless-steel tanks in freezing weather
conditions. Which consideration is MOST important when determining
the suitability of the synthetic slings?
A. Whether the sling color matches the designated site safety coding system
B. Whether the slings have been exposed to ultraviolet radiation during
storage
C. Whether environmental conditions and load edges could damage or
reduce sling performance
D. Whether the crane operator prefers synthetic slings over wire rope slings
C. Whether environmental conditions and load edges could damage or
reduce sling performance
Synthetic web slings are vulnerable to cuts, abrasion, temperature effects,
and environmental degradation. A rigging supervisor must evaluate edge
protection needs and environmental exposure to determine whether the
slings remain safe for the intended lift.
5. A rigging supervisor overseeing precast concrete installation notices
that the crane operator cannot clearly see the signalperson because of
structural obstructions. Which action best complies with safe lifting
procedures?
, A. Allow nearby workers to provide backup hand signals simultaneously
B. Suspend lifting operations until a reliable communication method is
established
C. Continue operations using only standard crane horn signals
D. Permit the operator to rely on personal judgment once the load clears the
ground
B. Suspend lifting operations until a reliable communication method is
established
Safe crane operations require continuous and reliable communication
between the operator and designated signalperson. If visibility or
communication is compromised, lifting operations must stop until an
effective communication system is established.
6. A rigging supervisor is planning to lift structural steel beams using a
two-leg bridle sling assembly. As the horizontal sling angle decreases,
what effect occurs on sling tension?
A. Sling tension decreases because the load is distributed over a larger area
B. Sling tension remains constant regardless of sling angle
C. Sling tension increases significantly as the sling angle becomes smaller
D. Sling tension decreases only when wire rope slings are used
C. Sling tension increases significantly as the sling angle becomes smaller
Lower sling angles create greater horizontal force components,
dramatically increasing tension within each sling leg. Rigging supervisors
must account for sling angle effects to avoid overloading rigging
components.
7. A rigging supervisor conducting a jobsite safety audit identifies
workers standing directly beneath a suspended load while guiding it
into place. What should the supervisor do immediately?
A. Permit the activity if the load weight is under one ton
B. Stop the lift and clear personnel from the fall zone beneath the
