MOBILE CRANE OPERATOR CORE EXAM
SCRIPT 2026 FULL QUESTIONS AND ANSWERS
ALREADY PASSED
◉ Boom stop. Answer: Includes boom stops, belly straps with
struts/standoff, telescoping boom stops, attachment boom stops, and
backstops, which restrict the boom from moving above a certain
maximum angle.
◉ Competent person. Answer: One who is capable of identifying
existing and predictable hazards in the surroundings or working
conditions and has authorization to take prompt corrective measures.
◉ Controlled load lowering. Answer: Lowering a load by means of a
mechanical hoist drum device that allows a hoisted load to be lowered
with maximum control using the gear train or hydraulic components of
the hoist mechanism.
◉ Drum rotation indicator. Answer: A device on a crane or hoist which
indicates in which direction and at what relative speed a particular hoist
drum is turning.
◉ Fall zone. Answer: The area (including but not limited to the area
directly beneath the load) in which it is reasonably foreseeable that
, partially or completely suspended materials could fall in the event of an
accident.
◉ Hoist. Answer: A mechanical device for lifting and lowering loads by
winding a line onto or off a drum.
◉ Hoisting. Answer: The act of raising, lowering or otherwise moving a
load in the air with equipment covered by this standard.
◉ List. Answer: The angle of inclination about the longitudinal axis of a
barge, pontoons, vessel or other means of flotation.
◉ Load moment (or rated capacity) indicator. Answer: A system which
aids the equipment operator by sensing (directly or indirectly) the
overturning moment on the equipment, i.e., load multiplied by radius.
◉ Load moment (or rated capacity) limiter. Answer: A system which
aids the equipment operator by sensing (directly or indirectly) the
overturning moment on the equipment, i.e., load multiplied by radius,
and when the rated capacity is reached, it shuts off power to those
equipment functions which can increase the severity of loading on the
equipment.
