Name: Score:51 Multiple choice questions
Term 1 of 51
What is the SAFE lifting angle for sling legs?
90 degrees to the horizontal
75 degrees to the horizontal
60 degrees to the horizontal with the minimum being 45 degrees or higher
30 degrees to the horizontal
Term 2 of 51
How is the center of the load determined?
By closing your eyes and pointing
By guessing the center point
By laying a sling across the load, marking the two pick up points or by using a tape
measure
By flipping a coin
Term 3 of 51
What are the guidelines are there for the Gantry or Monorail hoists?
Check the hoist before and service regularly, use the hoist properly, keep everybody
clear of load, do not wrap the hoist load chain around a load as a sling, do not ride on
moving loads, do not hotrod with a powered hoist
The resulting sling leg load stress on the eye bolts will be greater than if two separate
slings are used which will create a comprehensive force on the load.
Tighten before tension is placed on the ropes and re tighten after load has been applied
to the load
Name or trademark of manufacturer, diameter or size, type of material used, rated load
for given type of hitch, and lift angle upon which the load rating is based.
,Term 4 of 51
Why is it important to use the correct clip lay grooving to match the lay of the wire rope?
To increase the flexibility of the wire rope
Otherwise the grooving edges will cut across and damage the rope and wire strands
To prevent the wire rope from rusting
To reduce the weight of the wire rope
Term 5 of 51
How does overload easily happen on a chain fall hoist?
When overloaded, so take this as a warning to back off and not put a snipe or cheater
over the handle
It is due to the gearing system and two people on the hoist chain trying to lift more than
it is rated for
This creates an equilateral triangle where all the sides are the same lenghs
Tighten before tension is placed on the ropes and re tighten after load has been applied
to the load
Term 6 of 51
What do you do with defective components?
The jacks should be operated simultaneously, use temporary blocking under the load
after each jacking sequence, do not overload a jack by using a cheater bar, remove the
jacking handle when not performing the jacking process, do not leave the load on jacks
for extended periods, use blocking or cribbing.
Destroy defective components
Do not angular load it.
Do not angular load it.
,Term 7 of 51
What are the important load and site factors of the lift plan?
Shouldered is straight and unshouldered is pulled out at a max 30 degree angle and is
seated
The size and setup of the crane as well as the up to date inspection report, the step by
step movements of the crane and the environmental lifting conditions.
The most important precaution is to determine the weight of the load before attempting
to lift it
It identifies the size shape and weight of the load, where it will be lifted from, where it
will be placed and the placement of the cranes.
Term 8 of 51
What determines the size of the crane used, where it is placed and the required site
preparations?
The important load and site factors that are describe in the systematic assessment of the
lift plan.
The color of the crane used for the lift.
The number of coffee breaks allowed for the crane operators.
The weather conditions on the day of the lift.
, Term 9 of 51
What are the steps for proper clip installation?
always keep jacks vertical, avoid using only one jack, all jacks should be the same type
and capacity, use a piece of hardware between the jack and the load, and do not place
jack directly on the ground when using outside.
The size and setup of the crane as well as the up to date inspection report, the step by
step movements of the crane and the environmental lifting conditions.
Apply first clip one base width from dead end, apply second clip nearest eye as
possible, place all other clips, tighten all nuts to recommend torque and recheck torque
after rope has been in operation.
the jacks should be operated simultaneously, use temporary blocking under the load
after each jacking sequence, do not overload a jack by using a cheater bar, remove the
jacking handle when not performing the jacking process, do not leave the load on jacks
for extended periods, use blocking or cribbing.
Term 10 of 51
What happens to the load angle factor when the angle increases?
The load angle factor remains the same
The load angle factor becomes irrelevant
The load angle factor increases
The load angle factor decreases. Meaning the greater the angle degree the less weight
that can be lifted.
