MA 2A Exam with Questions and answers GRADED A (2026) WITH RATIONEL.
Question 1: What is the primary purpose of conducting a daily inspection before
operating a crane?
A) To comply with manufacturer's warranty requirements
B) To identify defects or conditions that could cause unsafe operation
C) To ensure the crane is clean and presentable
D) To record hours of operation for maintenance scheduling
Answer: B
Rationale: Daily inspections are required by OSHA and ANSI to identify any
damage, wear, or malfunction that could compromise safety. The operator is
responsible for conducting a pre-operational inspection before each shift .
Question 2: Which of the following is the maximum allowable wind speed for
crane operation unless the manufacturer specifies a lower limit?
,A) 20 mph
B) 25 mph
C) 30 mph
D) 35 mph
Answer: B
Rationale: While manufacturer specifications always take precedence, a common
rule of thumb is that crane operations should cease when wind speeds exceed 25
mph. Some cranes have lower limits, especially when handling large loads or using
a jib .
Question 3: When setting up a hydraulic crane with outriggers, the operator must
ensure that:
A) The outriggers are fully extended regardless of ground conditions
B) The outriggers are placed on firm, level ground and cribbing is used to
distribute the load
C) The outriggers are only used on paved surfaces
D) The outriggers are partially extended to save time
,Answer: B
Rationale: Outriggers must be placed on ground that can support the load without
settling. Cribbing (wooden mats, steel plates) must be used to distribute weight
and prevent sinking. The crane must be leveled using the outriggers .
Question 4: A "critical lift" is defined as:
A) Any lift over 10,000 lbs
B) A lift that requires a signal person
C) A lift where the load exceeds 75% of the crane's rated capacity, or where the
lift involves special hazards
D) A lift that requires a certified rigger
Answer: C
Rationale: A critical lift typically involves loads exceeding 75% of the crane's rated
capacity, lifts over personnel, lifts near power lines, or lifts involving hazardous
materials. These require a written lift plan and additional safety measures .
, Question 5: What is the standard hand signal for "boom up"?
A) Arm extended with thumb pointing upward
B) Arm extended with index finger pointing upward
C) Arm extended, fingers closed, thumb pointing upward
D) Arm extended, palm facing upward, making a circular motion
Answer: C
Rationale: Standard hand signals (ANSI/ASME B30.5) specify: for "boom up," the
signal person extends an arm horizontally with fingers closed and thumb pointing
upward. For "boom down," the thumb points downward .
Question 6: What is the purpose of a load-indicating device (LMI) or rated
capacity indicator (RCI)?
A) To automatically stop the crane when the rated capacity is exceeded
B) To provide the operator with continuous information about load weight,
radius, and percentage of capacity
