Rigging Test Questions
1/2" - ANS-Given the attached drawing, determine the minimum thread engagement for the 3/8"
eyebolt per the attached load
\100% - ANS-whenever anything is lifted or raised from a horizontal position to a vertical
position, the crane load will be equal to _________ the weight of the object until the object is
vertical and clears the ground
\1000 Ibs. - ANS-A four-point hook up is being used to lift 4000 Ibs. using a spreader bar such
that the legs are vertical with exact same length slings. With each leg carrying an equal load,
what is the stress on each sling?
\194 (90) - ANS-Per ASME standard nylon and polyester slings shall NOT be used in contact
with temperatures in excess of what degrees F (degree C)?
\194(90) - ANS-Per ASME Standard, fiber core wire rope slings of all grades shall not be
exposed to temperatures in excess of what degree F (degree C)?
\200% SWL - ANS-in a basket hitch the capacity of the sling will be:
\3080 Ibs. - ANS-A three-point hook up is being used to lift 800 Lbs. using a spreader bar such
that the legs are at 30-degrees off vertical. With each leg carrying an equal load, what is the
stress on each sling?
\360 - ANS-in addition to using flags and barricades to show the work zone near power lines,
the employer can define the work zone area ________ degrees around the equipment up to the
equipment's maximum working radius
\8 - ANS-the maximum number of parts of line that may be used when reeving fiber rope before
friction loss is greater than mechanical advantage is:
\adjust sling length - ANS-A turnbuckle is used to:
\after each use - ANS-turnbuckles should be inspected:
\air bearings - ANS-which friction reducing tool has the least amount of friction?
\angle - ANS-critical lifts are those where the load weight is close to the rated capacity of the
crane. When the lifting load weighs more than 75% of the rated capacity, or when lifts involve
two or more cranes, be sure to check the boom:
\as many as are required per the lift plan - ANS-How many persons may share a dedicated
channel for the purpose of coordinating operations?
\be removed from service - ANS-Knots tied in synthetic web slings or wire rope slings reduce
the SWL (safe work limit) by approximately 50% and therefore should:
\below the attachment points - ANS-where would the CG of a load be located during a lift?
\block - ANS-two-blocking occurs when the ___________ or headache ball makes contact with
the sheaves at the boom tip
\blocks installed at contact points - ANS-to ensure that correct sling angles are maintained
during choker hitch use, the sling may have:
\bowline in a bight - ANS-a knot that is used to form a loop at any point in the rope between its
ends is called a:
\bridge - ANS-the ___________ is the main structural member of an over head crane used to
span the width of the runway area
