,Crane Operator
1. The minimum crane team for a mobile crane on outriggers would
consist of-
A) The Crane Operator, Rigger Supervisor, and Crane Rigger
B) The Crane Operator, Crane Supervisor, Rigger Supervisor, and Crane
Rigger
C) The Crane Operator, Crane Supervisor, and Crane Rigger
D) The Crane Operator and Rigger-in-Charge
E) The Crane Operator, Crane Walker, and Crane Rigger
Correct Answer: C) The Crane Operator, Crane Supervisor, and Crane
Rigger
Rationale: A mobile crane on outriggers requires at minimum an operator
to control the crane, a supervisor to oversee the operation, and a rigger to
attach the load. The rigger supervisor is not always required for every lift,
making option C the standard minimum team.
2. When operating floating cranes, you must start swinging or rotating
quickly and stop smoothly to prevent excessive barge list.
A) True
B) False
Correct Answer: B) False
Rationale: Starting or stopping quickly creates dynamic forces that cause
the barge to list (tilt) excessively. Smooth, gradual starts and stops are
necessary to maintain stability.
3. Extending a telescoping boom without lowering the hoist may result
in "two-blocking" the crane.
,A) True
B) False
Correct Answer: A) True
Rationale: Extending the boom moves the upper sheaves upward. If the
hook block is already high, this reduces the space between them, which can
cause the hook block to contact the upper sheaves (two-blocking).
4. All of the following require a license to operate EXCEPT a(n)-
A) Cab-operated category 3 bridge crane
B) Mobile hydraulic truck crane
C) Non-cab operated category 3 bridge crane
D) Articulating boom category 4 crane
E) Floor-operated category 2 bridge crane
Correct Answer: C) Non-cab operated category 3 bridge crane
Rationale: Licensing requirements typically apply to cranes that are
operated from a cab or are mobile. A non-cab operated (e.g., pendant or
radio-controlled) bridge crane, depending on local regulations, often has
different or reduced licensing requirements for the operator, as the
operator is not riding on the machine.
5. Which of the following lift types would NOT be considered a
complex lift?
A) Multiple-crane lifts
B) Oxygen/Acetylene bottles in racks designed for lifting
C) Large geometric shapes
D) Loads with multi-level attachment points
E) Hazardous or explosive materials
, Correct Answer: B) Oxygen/Acetylene bottles in racks designed for
lifting
Rationale: A complex lift involves unusual challenges like multiple cranes,
unstable loads, hazardous materials, or difficult shapes. Lifting bottles in a
specially designed rack is a routine, engineered lift and does not inherently
add complexity.
6. What is the minimum amount of rope that shall be on a grooved
drum and a smooth drum?
A) There is no minimum
B) 4 full wraps, 2 full wraps
C) 2 full wraps, 3 full wraps
D) 6 full wraps, 4 full wraps
E) 1 full wrap, 2 full wraps
Correct Answer: B) 4 full wraps, 2 full wraps
Rationale: The rope anchor point is not designed to hold the load. The
friction from the wraps on the drum holds the load. Grooved drums need 4
wraps to ensure the anchor is not stressed, while smooth drums require at
least 2 wraps to prevent the rope from slipping.
7. The horizontal distance from the center of rotation of the crane to
the center of the hoist line(s) with load applied is called
A) Boom Length
B) Radius
C) Lift Zone
D) Quadrant
E) Circumference
Correct Answer: B) Radius
