OVERHEAD CRANE REVIEW EXAM ACTUAL
QUESTIONS AND ANSWERS SURE A+
✔✔What should be the first step in a daily inspection of an overhead crane? - ✔✔Check
the main switch (LOTO the main switch)
✔✔What should be done with an unbalanced load? - ✔✔Lower load to the floor
✔✔When making a lift, where should the load block be positioned? - ✔✔Vertically over
the load's center of gravity
✔✔Which of the items listed is most likely to be damaged by side loading an overhead
crane?
A) trolley rails
B) the wire rope
C) the drum lagging
D) the bridge girder - ✔✔The wire rope.
✔✔According to ASME, warning signals shall be given - ✔✔-Before starting the bridge
or trolley motion of the crane
-Intermittently during travel of the crane, when approaching persons in the path of the
load
, ✔✔According to AASME B30.2, an overhead crane equipped with a lower limit device
must have how many wraps left on the hoist drum, at its lowest point? - ✔✔One
✔✔According to OSHA, the proper time to check the hoist brake is - ✔✔During the first
lift—by lifting the load a few inches and applying the brakes. (In duty cycle and repetitive
lifts where each lift is 90% or more of its max line pull)
-otherwise, each time a load that is 90% or more of the max line pull is handled.
✔✔In the event of an emergency, who may give the stop signal? - ✔✔Anyone
✔✔According to ASME B30.2, before lifting a load, the hoist ropes will be free of kinks
and - ✔✔Twists, and shall not be wrapped around the load.
✔✔An object weighs 150 pounds per cuft, it measures 5'x3'x2'; how much does it
weigh? What is the formula? - ✔✔4,500 lbs; LxWxH=cuft x lbs/cuft= object weight
✔✔The purpose of the upper limit switch is to - ✔✔Limit upper hoist travel
✔✔According to OSHA, the operator SHALL not hoist loads above - ✔✔Personnel
✔✔Where should the hook block be positioned for shutdown? - ✔✔Near the upper limit
✔✔Whose responsibility is it to verify the controller buttons move appropriate functions,
in the correct direction? - ✔✔The operator
✔✔Before making a lift, the operator must for first determine which of the following:
A) Maximum POL
B) Center of gravity of the crane
C) Placement of taglines
D) Attachment points - ✔✔Attachment points
✔✔A wire rope designated as 6 x 19 has: - ✔✔Precisely 6 strands, with approximately
19 wires per strand (16-26)
✔✔The safe working load (SWL) of a wire rope is defined as: - ✔✔The breaking
strength divided by the safety factor
✔✔Who can authorize side loading of an overhead crane - ✔✔A qualified person (who
has determined that: various parts will not be overstressed, hoist rope will not bear or
rub against other parts not specifically designed for such contact, and that side pulls will
not cause the wire rope to be pulled out of the sheaves or across drum grooves)
