Question 1
A Class A operator is preparing a lattice-boom crane for a lift. The load chart provides
separate capacities for several boom lengths and operating radii. The planned load weight
is below the maximum capacity listed for the shortest boom, but the selected boom is
substantially longer. Which principle should govern the operator's decision?
A. Use the highest capacity appearing anywhere on the chart
B. Use the capacity corresponding specifically to the selected configuration and operating
radius
C. Average the capacities for the nearest two boom lengths
D. Use the capacity for the shortest boom because it provides the greatest safety margin
Correct Answer: B
- Explanation: Crane capacity must be determined from the manufacturer's applicable
chart for the actual configuration, including boom length and operating radius.
Question 2
,During planning, the operator determines that the load's center of gravity will be
approximately 5 feet farther from the crane's center of rotation than originally estimated.
Assuming all other conditions remain unchanged, what is the most appropriate response?
A. Proceed because the load weight has not changed
B. Increase operating speed to minimize exposure time
C. Recalculate capacity using the actual operating radius
D. Reduce the counterweight
Correct Answer: C
- Explanation: Increasing radius can substantially reduce rated capacity and increase
overturning moment, so the actual radius must be evaluated.
Question 3
A load chart lists capacities for several boom lengths but the operator cannot identify which
chart section applies to the crane's current counterweight configuration. What should the
operator do?
A. Select the chart with the greatest capacity
B. Use the chart from the previous lift
C. Stop and verify the exact manufacturer configuration and applicable chart
D. Reduce the load by 10 percent and proceed
Correct Answer: C
- Explanation: An unidentified configuration creates an unsafe capacity assumption; the
correct chart must be positively established before lifting.
Question 4
A crane has a rated capacity of 20,000 lb at a particular radius. The load weighs 17,500 lb,
and the rigging weighs 1,200 lb. The operator is also told that an auxiliary lifting device
adds another 900 lb to the suspended system. What is the total suspended load?
A. 17,500 lb
B. 18,700 lb
C. 19,600 lb
D. 20,500 lb
Correct Answer: C
- Explanation: The total suspended load is 17,500 + 1,200 + 900 = 19,600 lb.
Question 5
,A load chart indicates that capacity decreases as operating radius increases. Which physical
factor most directly explains this relationship?
A. Increased engine temperature
B. Increased overturning moment
C. Reduced wire-rope diameter
D. Increased hydraulic pressure
Correct Answer: B
- Explanation: A larger radius increases the load moment about the crane's tipping axis,
reducing available capacity.
Question 6
An operator is positioned at a radius that falls between two published load-chart radii. The
chart does not provide an interpolation method. What is the safest approach?
A. Use the higher capacity of the two entries
B. Use the lower capacity without further consideration
C. Determine the manufacturer's prescribed method or use a configuration clearly within
the published limits
D. Average the two capacities
Correct Answer: C
- Explanation: Operators should not invent interpolation methods; the manufacturer's
chart and instructions control the permissible capacity determination.
Question 7
A range diagram shows that the boom tip cannot physically reach a planned landing area at
the proposed boom angle. The load itself is within rated capacity. What is the controlling
issue?
A. Load weight
B. Mechanical reach and configuration limits
C. Engine horsepower
D. Hook-block weight only
Correct Answer: B
- Explanation: Capacity alone does not establish whether the crane can physically reach
the required position within its permitted configuration.
Question 8
, A 12,000-lb load is suspended from two equal sling legs arranged symmetrically at 60
degrees from the horizontal. Ignoring sling and hook weight, approximately what tension
exists in each sling leg?
A. 3,000 lb
B. 6,000 lb
C. 6,928 lb
D. 12,000 lb
Correct Answer: C
- Explanation: For two equal legs, each tension is approximately 12,000 ÷ (2 × sin 60°) =
6,928 lb.
Question 9
An operator notices that a planned lift will place the boom in a configuration for which the
chart contains a specific capacity restriction when working over the side rather than over the
rear. What should control the lift?
A. The highest capacity shown for any quadrant
B. The capacity applicable to the actual working quadrant
C. The crane's maximum structural capacity
D. The capacity used during the previous lift
Correct Answer: B
- Explanation: Rated capacity can vary by working quadrant, so the actual position and
configuration must be used.
Question 10
A load is lifted and begins to swing outward as the crane rotates. Which consequence is
most important from a capacity perspective?
A. The effective radius can increase
B. The load becomes lighter
C. The boom becomes shorter
D. The counterweight becomes heavier
Correct Answer: A
- Explanation: Outward swing increases operating radius and can therefore increase load
moment and reduce available capacity.
