2026/2027 ACTUAL QUESTIONS
WITH VERIFIED ANSWERS.
On a lattice boom crane, which position should the gantry
be in when lifting a load?
Highest position
Blocking angle type outriggers too high could cause:
Tipping axis reduction
The effect of external pressure on wire rope is described
as:
Crushing
Due to its tendency to untwist, which of these types of wire
rope should NOT be used on single part hoisting lines?
Lang lay
Rotation resistant wire rope sometimes has a lower
Working Load Limit than an equal sized regular lay wire
rope because:
Rotation resistant wire rope has a higher design factor
At what angle to the horizontal will the stress on each sling
leg (using 2 slings) be equal to the weight of the load?
30°
Extra load radius can be caused by:
Rapid swing
,Crane stability is based on:
The leverage principle
The effective weight of an attachment is:
Any of these options
The primary purpose of a jib is:
To increase tip height
When constructing crane mats, the best way to secure the
timbers together is to:
Bolt them together
When lifting a load out of water, you can expect:
The weight of the load to increase as the load displaces less
water
Unless otherwise noted by the manufacturer, lattice boom
sections should be added:
With the shorter sections installed toward the butt end.
The term "slew" means:
Swing
Quadrants of operation can be found in:
Work area diagram
Which of these functions could increase deflection of the
crane's boom?
Swinging the load
Which of these statements is true?
Jib capacities increase as the angle to the ground increases
, Which of the following would be okay to remove from a
carry deck crane for lifting operations?
Boom extension
Which of these functions can change a mobile crane's
quadrant of operation?
Swing
The angle between the legs of a 2-leg bridle hitch is
referred to as the
Included angle
OSHA refers to the area which it is reasonably foreseeable
that partially or completely suspended materials could fall
as the
Fall zone
It's okay to get under the crane's boom during
assembly/disassembly
When site constraints require it and A/D Director exercises
precautions
What is the purpose of a PTO?
To transfer power from the engine to the hydraulic pump
Having an outrigger partially retracted
Makes the tipping axis closer to the crane's center of gravity
What is the purpose of an anemometer?
To measure wind speed.
What device can be used to read boom length, radius and
load weight?
Rated Capacity Indicator
