NCCCO Mobile Crane Operator Candidate Handbook (2024)
The NCCCO Lattice Boom Truck (LBT) credential requires passing the Mobile Crane Operator Core written exam (90 questions, 90 minutes) plus the LBT specialty written exam (26 questions, 60 minutes), with no calculators permitted, and the corresponding practical exam within 12 months. The Core blueprint weights Site about 20%, Operations 26%, Technical Knowledge 28% and Load Charts 26%, while the specialty leans about 35% on manufacturers' load charts. Passing requires a scaled score equivalent to roughly 70%, and certification lasts five years. PPT written fees run about $180 for Core plus one specialty, or $75 for a specialty alone after the Core is passed. This 100-question bank gives original combined Core-plus-LBT practice covering load-chart and capacity calculations, setup and stability, assembly/disassembly, operations and OSHA 1926 Subpart CC safety.

1On a lattice boom truck crane load chart, what does the term 'gross capacity' represent?
2A load chart lists a gross capacity of 40,000 lb at a 30 ft radius with 80 ft of boom. The load block weighs 800 lb, the hook ball weighs 200 lb, and slings weigh 150 lb. What is the maximum load weight that may be lifted?
3On a lattice boom truck crane, capacities are typically GREATEST when the load is handled in which quadrant of operation?
4A range diagram on a lattice boom truck crane load chart is used primarily to determine:
5On a load chart, a heavy line or shaded boundary that separates the upper and lower portions of the capacity table most commonly indicates:
6A capacity chart shows 22,000 lb at a 40 ft radius and 16,000 lb at a 50 ft radius for the same boom length. As radius increases at a constant boom length, capacity generally:
7When a jib is erected on a lattice boom truck crane but is NOT being used to lift, how must its weight be treated on the main boom load chart?
8An over-rear on-outrigger chart lists 50,000 lb at 25 ft radius, while the over-side chart lists 30,000 lb at the same radius and boom length. An operator must swing a 35,000 lb load from over-rear to over-side. What is the correct conclusion?
9What does an on-outrigger load chart require regarding outrigger position?
10A load weighs 18,000 lb. The load block weighs 600 lb and the rigging weighs 400 lb. To stay within a rated capacity, the chart's gross capacity at the planned radius must be at least:
About the NCCCO LBT Exam
The NCCCO Lattice Boom Truck Crane Operator (LBT) certification qualifies operators to run truck-mounted cranes that use a bolted lattice (not telescoping) boom supported on outriggers. To certify, candidates pass the Mobile Crane Operator Core written examination, the LBT specialty written examination and the matching practical examination within 12 months. The Core exam (90 questions, 90 minutes) covers Site, Operations, Technical Knowledge and Load Charts; the LBT specialty exam (26 questions, 60 minutes) is weighted heavily toward manufacturers' load charts plus lattice boom setup, assembly/disassembly and operations. Both written exams are multiple choice and prohibit calculators. Certification is valid for five years, after which recertification is required.
Assessment
Combined written requirement: a 90-question Core examination plus the 26-question Lattice Boom Truck (LBT) specialty examination, all multiple choice. This bank provides 100 original combined practice questions.
Time Limit
90 minutes for the Core examination and 60 minutes for the LBT specialty examination; calculators are not permitted on either written exam.
Passing Score
Pass/fail based on a scaled score equivalent to about 70%. Because scoring is scaled across forms, the exact number of correct answers required is not fixed.
Exam Fee
PPT written fees: Core plus one specialty $180; one specialty only after passing Core $75; additional specialties cost more and a $50 late fee may apply. Practical exam fees are separate. Confirm current amounts at nccco.org/examfees. (National Commission for the Certification of Crane Operators (NCCCO / CCO))
NCCCO LBT Exam Content Outline
Load Charts and Capacity
Reading lattice-boom truck-crane rated-capacity charts by boom length, radius, quadrant (over-rear, over-side, 360 degrees) and outrigger position; range and work-area diagrams; gross versus net capacity; and deductions for the load block, hook ball, jib and other attachments. Includes calculation items.
Setup and Stability
Outriggers fully versus partially extended, position indicators, ground bearing pressure, mats, blocking and cribbing, leveling, and the difference between capacities limited by stability and those limited by structural strength. Covers backward (rear) stability limits on rubber and the role of counterweight.
Assembly and Disassembly
Lattice boom sections and inserts, jibs, gantry/mast, counterweight installation, and the assembly/disassembly (A/D) director's duties under OSHA 1926.1404. Covers pin and connection checks, blocking boom sections and erecting or lowering the boom safely.
Operations
Travel on rubber and on outriggers, hoisting, swinging and placing loads smoothly, multi-part reeving and load-block selection, parts of line versus line pull, and reacting to changing conditions including wind and shock or side loading.
Site Safety, Rigging, Signals and Regulations
Power-line minimum approach distances under OSHA 1926.1408, ground conditions, sling angles and rigging hardware capacity, wire rope inspection and replacement criteria, standard hand and voice signals, and OSHA 1926 Subpart CC and ASME B30.5 requirements.

Frequently Asked Questions
How many questions are on the NCCCO Lattice Boom Truck written exams?
The Mobile Crane Operator Core examination has 90 multiple-choice questions and the Lattice Boom Truck (LBT) specialty examination has 26 multiple-choice questions, for 116 written questions in total.
How long do I get for the LBT written exams?
You have 90 minutes for the 90-question Core examination and 60 minutes for the 26-question LBT specialty examination. Calculators are not permitted on either written exam.
What score do I need to pass?
NCCCO uses scaled scoring set at the equivalent of about 70%. Because scores are scaled across exam forms, the exact number of correct answers needed varies, and results are reported as pass or fail.
Is the Core exam enough, or do I also need the LBT specialty?
You must pass both. Every candidate takes the Core written exam, and to certify on lattice boom truck cranes you also pass the LBT specialty written exam plus the corresponding practical exam within 12 months.
How is a lattice boom truck crane different from a telescopic crane?
A lattice boom truck crane is a truck-mounted carrier with a bolted, open-lattice boom built from sections and inserts rather than a telescoping hydraulic boom. The LBT specialty covers lattice assembly, disassembly and load charts unique to that design.
How long is NCCCO certification valid?
CCO Mobile Crane Operator certification is valid for five years. Recertification is completed during the final 12 months before expiration and may waive the practical exam for operators who document at least 1,000 hours of relevant experience.
