ADVANCED RIGGING TEST EXAM
QUESTIONS AND VERIFIED CORRECT
ANSWERS WITH FULL COMPLETE
SOLUTIONS
the operational quadrant between the left-or-right-side outriggers is - ANS -over-
the-side
cranes are typically built to be - ANS -longer than they are wide
in a multiple-crane lift, the crane with the greatest net capacity must always be -
ANS -closest to the loads center of gravity
leverage is defined as - ANS -the power applied to a lever to cause the load to
move
the quadrant that is located between the rear outriggers or crawlers in the
rearward direction of travel is known as - ANS -over-the-rear
what dynamic occurs when a load is hoisted from a point other than directly over
the load - ANS -pendulum effect
the sudden release of a load that causes a rapid change in effective load weight is
called - ANS -acceleration
, backward stability of a crane is affected by - ANS -high boom angles and inclines
a loads center of gravity in relation to the tipping axis is affected by all of the
following except - ANS -raising or lowering the load
a cranes stability is affected by all of the following except - ANS -centered lift
to find the parts of line, the operator - ANS -divides the suspended weight by the
WLL of the hoist rope
a document that outlines all weight, rigging, and configuration requirements for a
lift is a - ANS -lift plan
when a bundle of rebar is being lifted with two slings in a choker hitch, the sling
eyes should be threaded in the opposite direction to improve load stability - ANS -
false
adjustable lifting beams are limited by - ANS -wire rope slings
spreader beams are tested at what percent of their rated capacity - ANS -125
the formula for determining the WLL of a bridle hitch is - ANS -WLL = (W)(H/L)(2)

legs)(2)
