Overhead Crane Operator / Rigger Training Course objectives
1. Given any selected overhead crane, the trainee will be able to perform a
pre-operational inspection of the crane .
2. Given the basic requirements for a lift, the trainee will be able to plan a lift
such that it can be accomplished efficiently, safely, and in complete
accordance NASA STD 8719.9, Goddard Space Flight Center (GSFC) GPR
8834.1, (GSFC) GPR 8719.1, OSHA 1910.179, and ANSI B30 Standards.
3. Given any selected overhead crane, the trainee will be able to perform
crane operation efficiently, safely, and in complete accordance NASA STD
8719.9, (GSFC) GPR 8834b, (GSFC) GPR 8719.1, OSHA 1910.179, and ANSI
B30 Standards.
4. Given a sample load composed of multiple elements of mixed shapes and
densities, trainee will be able to correctly determine total weight within +/-
5%.
5. Given a sample load composed of multiple elements of mixed shapes and
densities, trainee will be able to correctly determine the center of gravity
(CG) of the load within 6”.
6. Given load parameters and lift conditions for typical lifts, the trainee will be
able to properly select the rigging for each case based upon weight,
dimensions, weight distribution, and type of load, temperature, and
chemical influences.
7. Given examples of any of the rigging components commonly used, the
trainee will be able to visually inspect those components and detect errors.
8. Given a drawing and specifications for a lifting assembly, the trainee will be
able to select the proper components and assemble them accordingly.
9. Given a sample load and correct rigging components, the trainee will be
able to rig the load for a lift efficiently, safely, and in complete accordance
NASA STD 8719.9, Goddard Space Flight Center (GSFC) GPR 8834, (GSFC)
GPR 8719.1, OSHA 1910.184, and ANSI B30 Standards.
10. Given a fully rigged load, the trainee will be able to perform the lift as a
crane operator and as a rigger as part of a lift team using proper methods
and communication.

Rigging Terminology
Lets first look at some common components used in rigging
and lifting operations.
Wire Rope Slings
Wire Rope Thimble
Protects Wire Rope Sling Eye from being damaged or worn.
Chain Slings
Synthetic Rope Sling

Rigging Terminology
Nylon Slings
Type 1 : Triangle & Choker (TC) - Hardware on each
end produces the most effective choker hitch. Can
also be used in vertical and basket hitches.
Type 2 : Triangle & Triangle (TT) - Hardware on each
end for use in basket or vertical hitch.
Type 3 : Flat Eye & Eye (EE) - Popular, versatile sling
used in vertical, choker & basket hitches. Easy to
remove from underneath loads.
Type 4 : Twisted Eye & Eye (EE) - Eyes turned at a
right angle to sling body. Forms superior choker hitch
& allows better fit on crane hook in basket hitch.
Type 5 : Endless (EN) - Economical & adaptable sling
with no fixed wear points. Used in all hitches.
Type 6 : Reversed Eye (RE) - Extremely strong &
durable for continuous &/or abusive applications.
Wear pads on both sides of body.
Hoist Rings

Rigging Terminology
Synthetic Round Slings
Shackles
Not to
be used
for any
angular
Lifting
Due to the angular
lifting properties of
most lifts GSFC
recommends not using
this type for any
overhead lifting
Shouldered Eye Bolts
Not to be
used for
any
overhead
Lifting
Due to properties of
Un-Shouldered Eye
Bolts the use of this
type of Eye Bolt is
forbidden at GSFC for
any overhead lifting
