NEW YORK STATE CRANE OPERATOR CERTIFICATE OF
COMPETENCE — CLASS C BOOM TRUCK PRACTICE QUESTIONS
,Question 1
A boom truck is positioned on a work site where the manufacturer's load chart
permits a particular load only when the outriggers are fully deployed. One
outrigger cannot be fully extended because of an obstruction. What is the most
appropriate operating decision?
A. Use the full-outrigger capacity because three outriggers are fully extended
B. Reduce the load only by an amount estimated by the operator
C. Operate only under a load-chart configuration that specifically accommodates
the actual setup
D. Increase engine speed to compensate for the reduced outrigger extension
Correct Answer: C
Explanation: Crane capacity depends on the manufacturer's specified
configuration; an operator must not invent a reduced-capacity value.
Question 2
During a lift, the operator notices that the crane's actual operating radius is
greater than the radius used when selecting the load-chart capacity. What is the
primary concern?
A. Increased hydraulic oil temperature only
B. Reduced crane capacity and potentially reduced stability
C. Increased hoisting speed
D. Reduced fuel consumption
Correct Answer: B
Explanation: Increasing radius generally increases overturning moment and can
substantially reduce allowable capacity.
Question 3
A load weighs 8,000 lb and the rigging arrangement has a documented total
rigging weight of 450 lb. What minimum load weight should be considered before
comparing the lift with the crane's rated capacity?
A. 7,550 lb
B. 8,000 lb
,C. 8,450 lb
D. 8,900 lb
Correct Answer: C
Explanation: The crane must account for the lifted load plus applicable below-
the-hook equipment, making the calculated lifted weight 8,450 lb.
Question 4
Which condition most directly threatens boom truck stability during a lift?
A. Low engine coolant temperature
B. Excessive load moment at an extended working radius
C. Clean hydraulic oil
D. Low ambient noise
Correct Answer: B
Explanation: Load moment increases as load and operating radius increase,
directly affecting stability.
Question 5
An operator is given a load weight by a worker who says the weight is
"approximately" 12,000 lb. The load chart permits 12,200 lb under the intended
configuration. What should the operator do?
A. Lift because the stated weight is below chart capacity
B. Lift slowly to determine whether the crane can handle it
C. Establish a reliable load weight before proceeding
D. Reduce boom angle until the load becomes easier to control
Correct Answer: C
Explanation: A narrow capacity margin combined with uncertain load weight is
insufficient for a safe professional lift.
Question 6
Why is the crane's load radius measured from the appropriate center of rotation
rather than from the truck body edge?
, A. The truck body edge determines hydraulic pressure
B. The center of rotation establishes the geometric basis for load moment
C. The truck body edge is always farther from the load
D. Radius is relevant only to transportation
Correct Answer: B
Explanation: Load moment calculations depend on the horizontal distance
between the crane's center of rotation and the load's effective center.
Question 7
A crane has a rated capacity of 10,000 lb at a particular configuration. A 9,500-lb
load has 700 lb of applicable rigging and lifting accessories. What is the correct
conclusion?
A. The lift is within capacity because the load itself is below 10,000 lb
B. The lift is within capacity because rigging is excluded
C. The total lifted weight exceeds the stated capacity
D. The lift is automatically permitted if the boom is raised slowly
Correct Answer: C
Explanation: The 10,200-lb combined lifted weight exceeds the 10,000-lb rated
capacity.
Question 8
What is the principal purpose of a crane manufacturer's load chart?
A. To establish recommended engine oil viscosity
B. To define permissible lifting capacity under specified configurations
C. To determine roadway speed
D. To establish operator wages
Correct Answer: B
Explanation: Load charts establish allowable capacities based on variables such
as boom length, radius, configuration, and operating conditions.
