RIGGING CML MASTERLIST EXAM
QUESTIONS AND ANSWERS GRADED A+
2025/2026
A [?] is a dolly consisting of two forks that are hydraulically lifted above a set of wheels. -
ANS pallet jack
Why would you complete a test lift? - ANS To confirm load balance and stability
There must be enough space for the maximum [?] of the crane and its surrounding safe zone
while in operation. - ANS footprint
Which one of these conditions would make it a lift complex? - ANS Hoisting in a nuclear
facility
When lifting a load that may swing uncontrollably, what is a good method to control the load? -
ANS tag line
In a prelift check, what should be done prior to the actual lift to help find any additional issues?
- ANS dry run

, Many cranes require a firm, graded, and [?] area for initial assembly and operation. -
ANS well drained
The size of a fall zone depends on what? - ANS size of the load
Complex lifts may require multiple signalpersons stationed at different locations, such as [?] . -
ANS enclosed spaces
When giving the [?] signal, the signalperson must watch the crane for two-blocking. -
ANS Extend Telescoping Boom
Which types of signals may be useful in extremely noisy environments or areas with significant
radio interference? - ANS audible signals
There are how many standard signals a qualified signalperson must be familiar with? -
ANS 21
What Subpart is Signals for Cranes & Derricks in construction found under? - ANS Subpart CC
Calculate the following asymmetrical rigging scenario. The load to be lifted has lift points 120
inches apart. The center of gravity is located 80 inches from point A. If the load is 9,000 pounds,
what is the weight experienced by point B? - ANS 9,000 × 80/120 = 9,000 × 0.6667 = 6,000 lb
What is the total material weight of a load consisting of 35 pieces of 4-foot by 8-foot steel
sheets that are 1/16 inches thick? Note: A steel sheet at 1/16 inches thick weighs 2.55 pounds
per square foot (psf). - ANS 4 ft × 8 ft = 32 ft2 --> 32 ft2 × 2.55 psf × 35 pieces = 2,856 lbs
Lifting Force can be measured directly with either a dynamometer or a [?] . - ANS load cell
