Preparation
Question 1
When placing mats or cribbing under outrigger floats, what is the primary engineering
purpose?
A. Increase crane speed
B. Reduce hydraulic pressure
C. Distribute load over a larger area
D. Prevent boom extension
Correct Answer: C. Distribute load over a larger area
Rationale:
Mats or cribbing are used to spread the crane’s load over a wider surface area,
reducing ground pressure and preventing soil failure or sinking. Option A is incorrect
because mats do not affect operational speed. Option B is incorrect because hydraulic
pressure is not directly reduced by cribbing. Option D is incorrect because cribbing is
unrelated to boom extension control.
Question 2
Where is the most appropriate location to level a crane?
A. Lowerworks
B. Tires
C. Upperworks
D. Boom tip
Correct Answer: C. Upperworks
Rationale:
Crane leveling is performed using the upperworks to ensure the entire structure
operates on a stable, balanced reference point. Tires and lower components may
,2026/2027
deform under load, making them unreliable. Boom tip is unrelated to leveling
operations.
Question 3
Before operating a mobile crane on outriggers, what condition must be ensured?
A. Tires are fully inflated
B. Crane weight rests on tires
C. No crane weight is bearing on tires
D. Boom is fully extended
Correct Answer: C. No crane weight is bearing on tires
Rationale:
Outriggers must fully support the crane to ensure stability. If weight remains on tires,
uneven load distribution may cause tipping. Tire inflation and boom position do not
ensure structural stability during outrigger use.
Question 4
When operating a long-boom mobile crane on uneven ground, what support principle
is most critical?
A. Increase boom speed
B. Maintain 90° angle between cylinder rod and pad
C. Reduce counterweight
D. Use tires for stabilization
Correct Answer: B. Maintain 90° angle between cylinder rod and pad
Rationale:
Maintaining proper cylinder alignment ensures even load distribution and structural
integrity. The other options do not address stability mechanics and may increase risk
of overturning.
Question 5
Under what condition may blocking be placed under outrigger beams?
A. Always permitted
B. Only on soft ground
C. Never permitted
D. Only when manufacturer allows
Correct Answer: C. Never permitted
,2026/2027
Rationale:
Placing blocking under outrigger beams is not approved because it compromises
structural integrity and load distribution. Proper pads or mats are used instead.
Question 6
What is the maximum allowable crane slope during setup?
A. 5%
B. 3%
C. 1%
D. 10%
Correct Answer: C. 1%
Rationale:
OSHA guidance requires cranes to be nearly level, typically within 1% grade, to
maintain stability and accurate load chart calculations.
Question 7
Timber crane mats are most effective when:
A. Loose laid
B. Bolted together
C. Painted
D. Stacked vertically
Correct Answer: B. Bolted together
Rationale:
Bolting mats ensures structural stability and prevents shifting under load, improving
ground pressure distribution.
Question 8
When arriving at a job site, the first condition an operator should evaluate is:
A. Weather conditions
B. Access roads
C. Load weight
D. Boom length
Correct Answer: B. Access roads
, 2026/2027
Rationale:
Safe crane access depends on ground stability and approach routes. Without proper
access evaluation, setup becomes unsafe.
Question 9
Which surface is unsuitable for crane setup?
A. Compacted gravel
B. Concrete slab
C. Underground vaults
D. Stabilized soil
Correct Answer: C. Underground vaults
Rationale:
Underground structures may collapse under crane load, creating catastrophic failure
risk.
Question 10
Each outrigger pad must support:
A. Half crane weight
B. Only boom weight
C. Entire crane and load weight
D. Counterweight only
Correct Answer: C. Entire crane and load weight
Rationale:
Outriggers distribute full operational load safely; each pad must be capable of
handling maximum expected forces.
Question 11
High wind conditions affect a long-boom crane by:
A. Increasing lifting power
B. Reducing fuel usage
C. Introducing side loading
D. Stabilizing boom
Correct Answer: C. Introducing side loading
