Rigging Test - Chapter 1-3
Terms in this set (55)
What is rigging? Using a hoist to move an object from one place to another
T/F? True
Riggers select the rigging hardware,
connect the rigging hardware to heavy
objects, and directs hoisting, moving, and
placing of these heavy objects:
What five intentions are the basis for the Wedge, lever, wheel, pulley, and screw
first tools?
Lengths of wood timbers or steel beams C. Cribbing
used to temporarily support construction
materials and equipment are:
A. Lever More
B. Tackle
C. Cribbing
D. Fulcrum
T/F? True
While the equipment used to move, raise,
and place heavy objects has evolved over
the centuries, the application of basic
rigging knowledge and techniques has
changed very little:
A simple machine consisting of a rigid bar D. Lever
pivoted on a fixed point and used to
transmit force, as in raising or moving a
weight at one end by pushing down on the
other is also known as a:
A. Wedge
B. Cribbing
C. Pulley
D. Lever
List three types of craftspeople who are Millwrights, carpenters, and pile drivers
also considered riggers
What is the most important factor to the Safety
success of any rigging operation?
T/F? True
WLL stands for working load limit:
, What formula is used to determine the WLL WILL= 8(D^2)
of wire rope? D=diameter of rope
What four items should be included in a rigging required, site prep, crane configurations, crane and load position
written rigging plan?
The load radius, boom length, and boom Accidents
angle must be determined for the entire
hoisting operation in order to prevent _______
from happening
How is the gross weight of a load total weight of load + rigging hardware
calculated? *Everything under the hook
T/F? True
Critical hoists should not be performed in
strong wind conditions:
T/F? True
Everyone involved in rigging operations
should be familiar with the standards that
apply:
What are the three components of wire Wire, strand, and core
rope?
Friction between the wires and strands will Rigged
restrict load distribution if the rope is not
properly ______
What are the two limiting factors that can Grade of steel & configuration of a choker
affect the versatility of wire rope?
Elevators often use wire rope made from D. Traction
____ steel:
A. Crucible cast
B. Plow
C. Mild plow
D. Traction
T/F? false (only larger, not smaller)
Outer wires are alternately larger and
smaller in the Seale wire strand
arrangement:
as the number of wires per strand increases
increases, the resistance to bending
fatigue______.
as the number of wires per strand decreases
increases, the resistance to wear_____.
T/F? true
Not all wire rope in each classification will
have the same number of wires per strand,
but the number of strands will remain
constant:
What is the most commonly used c. 6 x 19 standard hoisting
classification of wire rope in rigging
application?
a. 6 x 7 standard coarse laid
b. 6 x 37 extra flexible hoisting
c. 6 x 19 standard hoisting
d. flattened strand
