TESTED QUESTIONS).
1. When cranes are erected, load limiting devices shall be tested for proper
setting and operation:
a. Before crane is placed in service
b. After the first load is lifted
c. At the end of the first shift
d. Only during annual inspection
Correct Answer: a. Before crane is placed in service
Expert Rationale: Load limiting devices must be tested for proper setting and
operation before the crane is placed in service. This is a critical safety requirement
because these devices (such as load moment indicators, overload warning
systems, and anti-two-block devices) are essential for preventing crane
overloading and accidents. Testing these devices before the crane is used ensures
that they are functioning correctly and will provide the necessary protection
during operations. ASME B30.3 requires that load limit device settings be verified
by means of a static test using test loads of 102.5% to 110% of the applicable
rating. The operator must ensure that all load limiting devices are tested and
verified before the crane is put into service. This requirement applies to both new
erections and re-erections of tower cranes. Failure to test these devices could
result in a crane being operated without adequate overload protection, which
could lead to catastrophic failure and serious injury or death.
,2. Hooks shall be equipped with latches unless the application makes the use
of the latch:
a. Impractical
b. Dangerous
c. Expensive
d. Time-consuming
Correct Answer: a. Impractical
Expert Rationale: Hooks shall be equipped with latches unless the application
makes the use of the latch impractical. Safety latches on crane hooks are essential
for preventing loads from accidentally slipping off the hook. However, there are
certain applications where the use of a latch is impractical, such as when working
with certain types of rigging or when the latch interferes with the safe operation
of the crane. In these cases, the latch may be removed or disabled, but the
operator must take extra precautions to ensure the load is secure. The decision to
operate without a latch should only be made when it is truly impractical to use
one, and the operator should be aware of the increased risk. OSHA
1910.180(d)(3)(v) specifies that hooks must not be twisted in excess of 10 degrees
and that throat openings must not exceed 15% of their original size. These
requirements help ensure the integrity of the hook even when latches are not
used.
3. Size and position of signs or panels must satisfy the limitations of:
a. Manufacturer
b. OSHA
c. ASME
d. Site conditions
,Correct Answer: a. Manufacturer
Expert Rationale: The size and position of signs or panels must satisfy the
limitations of the manufacturer. The crane manufacturer has specific requirements
for the placement and size of signs, panels, and other markings on the crane.
These requirements are based on the crane's design, capacity, and operational
characteristics. The manufacturer's specifications ensure that signs and panels are
clearly visible and provide accurate information to the operator. The signs must
be placed in locations where they can be easily read and where they will not
interfere with the crane's operation. The manufacturer's requirements are typically
detailed in the crane's operator manual and maintenance manual. Operators and
maintenance personnel must follow these requirements to ensure that all signs
and panels are properly installed and maintained.
4. Fall prevention measures are needed for working at locations where you
are exposed:
a. To a fall of 6ft or more
b. To a fall of 10ft or more
c. To a fall of 4ft or more
d. To any fall hazard
Correct Answer: a. To a fall of 6ft or more
Expert Rationale: Fall prevention measures are needed for working at locations
where you are exposed to a fall of 6 feet or more. OSHA regulations require fall
protection for construction workers when they are working at heights of 6 feet or
more above a lower level. This includes working on tower cranes, where workers
may be exposed to falls during erection, climbing, maintenance, and dismantling
operations. Fall protection measures can include guardrails, safety nets, personal
, fall arrest systems, or other approved methods. The 6-foot threshold is specific to
the construction industry; in general industry, the threshold is 4 feet. Tower crane
operators and maintenance personnel must be aware of fall protection
requirements and must use appropriate fall protection equipment when working
at heights. OSHA 1926.501 requires that employers provide fall protection
systems for workers exposed to falls of 6 feet or more.
5. Travel distance on hand levers shall not be greater:
a. than 14 inches from neutral position
b. than 12 inches from neutral position
c. than 10 inches from neutral position
d. than 8 inches from neutral position
Correct Answer: a. than 14 inches from neutral position
Expert Rationale: Travel distance on hand levers shall not be greater than 14
inches from the neutral position. This requirement ensures that the operator can
reach and operate the controls comfortably and safely. If the controls are too far
from the neutral position, the operator may have difficulty operating them quickly
and accurately, which could lead to errors and accidents. The 14-inch maximum
travel distance is a standard ergonomic requirement for crane controls. It helps
prevent operator fatigue and ensures that the operator can maintain proper
control of the crane. The operator must be able to reach all controls easily from
the normal operating position. If the controls are not within the required range,
adjustments should be made to ensure the operator can operate the crane safely.
