B. It generally authorizes operation of cranes having a total boom length under 200
,feet, subject to applicable restrictions and endorsements
C. It authorizes only tower cranes below 200 feet in height
D. It authorizes only cranes with rated capacities below 50 tons
Correct Answer: B
Explanation: A Class A license generally covers cranes with total boom length under
200 feet, while equipment-specific certification and other restrictions may further
limit what the operator may legally operate.
Question 2
An applicant has accumulated three years of qualifying Class A experience during the
applicable period. Two years were operating mobile cranes rated above 50 tons, while
the remaining year involved qualifying mobile cranes below 50 tons. What is the
principal reason this experience distribution is significant?

B. A substantial portion of qualifying experience must involve larger mobile cranes or
tower cranes
C. Experience on cranes below 50 tons is prohibited
D. Only experience outside New York City is accepted
Correct Answer: B
Explanation: Class A qualification requires substantial experience operating mobile
cranes above 50 tons or tower cranes, with the remaining qualifying experience
permitted on specified equipment.
Question 3
A candidate claims crane experience accumulated over several nonconsecutive
employment periods. Which principle most directly applies?
A. Experience must always be consecutive
B. Only the most recent employer's experience counts
C. Qualifying experience may accumulate over separate periods if the required
cumulative experience is satisfied
D. Experience is counted only in calendar years containing twelve continuous months

Explanation: Qualifying experience does not necessarily have to be sequential; the
, required periods may be accumulated when the applicable requirements are
otherwise satisfied.
Question 4
A Class A applicant already possesses a qualifying Class C HMO license. Which
licensing-experience provision can materially affect the required crane setup
experience?
A. All setup requirements disappear
B. The requirement for the remaining 75 setups may be waived
C. All 100 setups must be performed on tower cranes
D. The applicant must complete 200 additional setups
Correct Answer: B
Explanation: An existing Class C license can affect the Class A setup requirement,
including waiver of the remaining 75 setups under the applicable rules.
Question 5
A Class A applicant reports 100 crane setups but cannot establish that the setups
included the required larger-capacity machinery. What is the primary concern?
A. Setup quantity alone automatically satisfies every requirement
B. The type of equipment used during the setups can be relevant to qualification
C. Setup documentation is never necessary
D. Only crane height matters
Correct Answer: B
Explanation: Qualification requirements can specify both the number of setups and
the equipment on which specified setups occurred.
Question 6
A candidate completed a required Department-approved HMO course more than one
year before submitting the Class A application. What is the most appropriate
conclusion?
A. The course is automatically valid indefinitely
B. The applicant should determine whether the course still satisfies the applicable
timing requirement
, C. The course can be substituted with any safety orientation

the approved course must have been completed.
Question 7
Which combination represents the three primary national certifications required for a
Class A HMO license?
A. Tower crane, lattice boom, and dedicated pile driver
B. Telescopic fixed cab, telescopic swing cab, and lattice boom crane
C. Articulating boom, tower crane, and telehandler
D. Fixed cab, tower crane, and derrick
Correct Answer: B
Explanation: The Class A certification package includes telescopic boom crane fixed-
cab, telescopic boom crane swing-cab, and lattice boom crane certifications.
Question 8

three basic Class A certifications. What additional credential is generally required?
A. No additional credential
B. Tower Crane certification
C. Dedicated pile driver certification
