Core
95 questions / 90 minutes. Site, operations, technical, load charts. Study Calc pad is on the quiz; CCO Core written is still no-calculator.
Mobile crane written prep
Read the chart. Make the pick.
Original Core + TLL / TSS / LAT practice, photo-heavy lessons, and 3D lift-plan questions that force you to read a training chart — not flashcards in a vacuum.
418 original items in the bank. Independent of NCCCO / CCO.
What you sit for
Specialty
TLL, TSS, or LAT — 26 questions / 60 minutes. Chart math is the washout.
3D lifts
Interactive boom, radius, outriggers, and a live net-capacity HUD.
Companies
Register as a company, not a student. Send a quiz link to a new hire before you put them on iron, or to operators already on payroll so they can check and refresh Core, TLL, TSS, and LAT knowledge. They do not need a login. Scores land on your company desk.
New-hire screen
Share a Core or specialty check. The taker does not see the key or their score. You do.
Crew refresh
Text the same style of link to employed operators. They see the score at the end so they know what to restudy.
Photo lessons
Ground, mats, and outriggers
The chart assumes the machine is level on something that will not punch through.
Power lines and Table A
Assume energized. Clearance is measured to boom, line, and load — whichever is closest.
Signals, stop authority, blind picks
One signal person when you cannot see. Anyone can stop the lift.
Two-blocking, LMI, and operator aids
Aids fail. You still owe the chart.
Rope, hooks, and hitch math
If the hitch is wrong, the chart on the crane will not save you.
Gross, net, radius, next-longer
This is the part of the written that washes people out. Drill it until it is boring.
