"When using outrigger jacks to level a crane, what is the best procedure to follow? - CORRECT
ANSWER=> Make firm contact with all four jacks. Then operate two jacks at a time on either side
of the lowest corner to get to level. Last, make sure the crane is high enough to have the tires
off the ground."
"How does the use of outriggers increase the tipping capacity of a crane? - CORRECT ANSWER=>
By moving the tipping axis further from the center of gravity of the crane"
"Many load charts for cranes state that the area of least stability is over the side. What
statement explains this the best? - CORRECT ANSWER=> The distance between the crane's center
of gravity and the tipping axis is smallest in that quadrant."
"List two examples of outrigger use in which the crane's leverage on the load is reduced. -
CORRECT ANSWER=> Outriggers not fully extended, tires not off ground"
"According to OSHA 29 CFR 1910.180, how accurate must a load weight be if it is in the
structural portion of the load chart? - CORRECT ANSWER=> Plus of minus 10%"
"Based on OSHA and ASME standards, which of the following conditions are required for
blocking or cribbing? - CORRECT ANSWER=> • Blocking/Cribbing must provide 100% support for
each float,
• Must be large enough in area² to prevent sinking,
• Must be strong enough to prevent crushing, bending, or shear failure."
"According to OSHA, when can an operator leave his seat with a suspended load in the air? -
CORRECT ANSWER=> Almost never (and the exception requires that four conditions be met)"

"Listen seven ideal conditions for crane operation. - CORRECT ANSWER=> 1) Not windy
2) Clear vision (no fog)
3) Sunny (Dry)
4) Crane is maintainenced (greased)
5) Crane is assembled correctly
6) Load is static
7) Site is level"
"List four things an operator should consider when deciding how much, if any, to reduce
operating capacity in the wind. - CORRECT ANSWER=> 1) If speeds are 20mph
2) Direction of wind
3) Surface area of boom length & load
4) Manufacturers instructions"
"What type of capacity is listed on a crane load chart? - CORRECT ANSWER=> Static"
"List two reasons crane manufacturers require reductions in capacity for duty cycle work. -
CORRECT ANSWER=> 1) dynamic loading
2) increased radius"
"Is there an official requirement that requires each outrigger float on blocking to be 100%
supported? - CORRECT ANSWER=> Yes. This is enquires"

, “Which area do truck cranes without a 5th outrigger generally have no lifting capacity unless
the manufacturer states otherwise? - CORRECT ANSWER=> The front"
"What is the definition of "operating radius?" - CORRECT ANSWER=> The distance from the
center of rotation of the crane to the center of gravity of the load"
"What applies to the capacities below the bold line shown on a load chart? - CORRECT
ANSWER=> They are based on the stability of the crane"
"In which quadrant are rough terrain crane capacities generally greater? - CORRECT ANSWER=>
Over the front"
"What percentage do most manufacturers requires a crane's load chart capacity to be reduced
by for duty cycle operations - such as high-volume concrete placement? - CORRECT ANSWER=>
20%"
"From which two points should the boom be measured? - CORRECT ANSWER=> From the boom
hinge pins, to the center of the boom tip sheave"
"What is the preferred method of installing wire rope from a reel onto a hoist drum? - CORRECT
ANSWER=> Running the rope from the top of the reel, to the top of the drum."
"Over which quadrant are truck crane capacities usually greater? - CORRECT ANSWER=> Over the
rear"
"According to OSHA, which accessible area of an operating crane must always be barricaded? -
CORRECT ANSWER=> The swing radius of the rear of the rotating superstructure"
"What is the OSHA regulation governing cranes in construction? - CORRECT ANSWER=>
1926.1400"
"According to ASME, what percentage of the manufacturer's crane rating must not be exceeded
if a load test is done on a repaired crane? - CORRECT ANSWER=> 100%"
"Where is the tipping axis of a crawler crane located? - CORRECT ANSWER=> It depends if the
idler or sprocket are in line or offset from the track rollers"
