Grade 80 Chain
GENERAL INFORMATION
WORKING LOAD LIMIT

ATTACHMENTS

The “Working Load Limit” is the maximum load which should ever
be applied to chain, when the chain is new or “in as new” condition,
and when the load is uniformly applied in direct tension to a straight
length of chain.

Any attachments, such as hooks or links, should have a rated
“Working Load Limit” at least equal to the chain with which it is
used.

PROOF TEST

Only Crosby Alloy chain, Spectrum 8® or Spectrum 10®, should
be used for overhead lifting applications.

The “Proof Test” is a term designating the tensile test applied to
new chain for the sole purpose of detecting injurious defects in the
material or manufacture. It is the load which the chain has withstood under a test in which the load has been applied in direct tension to a straight length of chain.

ANSI / ASME B30.9c-1997
Paragraph 9-1.4.2 “Mechanically assembled slings shall be
comprised entirely of proof tested components.” Paragraph
9-1.4.2c “If untested components are employed, the sling shall be
proof tested per Para. 9-1.4.1 prior to initial use.”

MINIMUM ULTIMATE LOAD

CAUTION

It must be recognized that certain factors in the usage of chain
and attachments can be abusive and lessen the load that the
chain or attachments can withstand. Some examples are twisting
of the chain, disfigurement, deterioration by straining,
usage, weathering and corrosion, rapid application of load or jerking and applying excessive loads, and sharp corners cutting action.
Due to the crushing effect Grab Hooks have upon chain, the
design factor of all chain assemblies must be reduced by 20% for
Grab Hook applications.

The “Minimum Ultimate Load” is the minimum load at which new
chain will break when tested by applying direct tension to a straight
length of chain at a uniform rate of speed in a testing machine.

CHAIN INSPECTION
INSPECTION AND REMOVAL FROM SERVICE PER
ANSI B30.9
FREQUENT INSPECTION
Normal Service - Monthly
Severe Service - Daily to Monthly
Check chain and attachments for wear, nicks, cracks,
breaks, gouges, stretch, bend, weld splatter, discoloration
from excessive temperature, and throat openings of hooks.
1. Chain links and attachments should hinge freely to
adjacent links.
2. Latches on hooks, if present, should hinge freely and seat
properly without evidence of permanent distortion.
PERIODIC INSPECTION - INSPECTION RECORDS
REQUIRED
Normal Service - Yearly
Severe Service - Monthly
This inspection shall include everything in a frequent inspection
plus each link and end attachment shall be examined
individually, taking care to expose inner link surfaces of the chain
and chain attachments.
1. Worn links should not exceed values given in table 1 or recommended by the manufacturer.
2. Sharp transverse nicks and gouges should be rounded out
by grinding and the depth of the grinding should not exceed
values in Table 1.
3. Hooks should be inspected in accordance with ANSI B30.10
4. If present, latches on hooks should seat properly, rotate
freely, and show no permanent distortion.
5. Chains use OSHA and ASME regulations and safety
information.

Three-and four-leg slings

Two leg slings

The design factor of 4 to 1 on Grade 80 Alloy Chain agrees with the design factor used by the International Standards
Organization (I.S.O.) and ANSI B30.9 is the preferred set of Working Load Limit values to be used.

TO MAKE YOUR CROSBY GRADE 8® ALLOY CHAIN SLING
Follow these simple steps in making a sling assembly:
Determine the maximum load to be lifted by the sling
assembly.
Choose the type of sling assembly suited for the shape of the
load and the size of the sling assembly for the load to be lifted.
The decision must take into account the angle of the sling legs in
multileg slings.
Determine the overall reach for bearing point of master link to
bearing point on hook.
Select components, assemble chain and components. Affix sling
identification tag to sling. The tag is available from your Crosby
Distributor. The tag should be stamped with size chain, reach,
type sling, Working Load Limit at a specific
angle of lift, and some identifying number for record keeping.

164

If measurement comes in the link, cut the following link. For two
leg type slings count the links and use an even number for clevis
hooks and an odd number for eye hooks. This will
position hooks in the same plane. In multileg slings always use
the same number of links in each leg.

CAUTION

Derate sling in accordance with working load limit chart shown
above.
A chain grab hook application will result in 20% reduction of chain
capacity.
Care should be taken to observe these derated applications or
chain may fracture or permanently stretch at loads less than the
advertised chain ultimate strength and proof load respectively.

and the other on the hook tip, which allows for a QUIC-CHECK® measurement to determine if the throat opening has changed, thus indicating abuse or overload. To check, use
a measuring device (i.e., tape measure) to measure the distance between the marks. The
marks should align.If the measurement does not meet this criteria, the hook should be
inspected further for possible damage.
• Angle Indicators: Indicates the maximum included angle which is allowed between two (2)
sling legs in the hook. These indicators also provide the opportunity to approximate other
included angles between two sling legs.

Grade 100 Alloy Chain
GENERAL INFORMATION
WORKING LOAD LIMIT
The “Working Load Limit” is the maximum load in tons which
should ever be applied to chain, when the chain is new or “in
as new” condition, and when the load is uniformly
applied in direct tension to a straight length of chain.

PROOF TEST
The “Proof Test” is a term designating the tensile test applied
to new chain for the sole purpose of detecting injurious defects
in the material or manufacture. It is the load which the chain
has withstood under a test in which the load has been applied
in direct tension to a straight length of chain.

ANSI / ASME B30.9c-1997
Paragraph 9-1.4.2 “Mechanically assembled slings shall be
comprised entirely of proof tested components.” Paragraph
9-1.4.2c “If untested components are employed, the sling shall
be proof tested per Para. 9-1.4.1 prior to initial use.”

MINIMUM ULTIMATE LOAD
The “Minimum Ultimate Load” is the minimum load at which
new chain will break when tested by applying direct tension to

CHAIN INSPECTION
INSPECTION AND REMOVAL FROM SERVICE PER
ANSI B30.9

a straight length of chain at a uniform rate of speed in a testing
machine.

ATTACHMENTS
Any attachments, such as hooks or links, should have a rated
“Working Load Limit” at least equal to the chain with which it
is used.

CAUTION

Only Crosby Alloy chain, Spectrum 8 ® or Spectrum 10®,
(Grade 80 or Grade 100) should be used for overhead lifting
applications.
It must be recognized that certain factors in the usage of chain
and attachments can be abusive and lessen the load that the
chain or attachments can withstand. Some examples are twisting of the chain; disfigurement; deterioration by straining,
usage, weathering and corrosion; rapid application of load or
jerking, applying excessive loads; and sharp corners cutting
action.
Due to the crushing effect Grab Hooks have upon chain, the
design factor of all chain assemblies must be reduced by 20%
for Grab Hook applications.

FREQUENT INSPECTION
Normal Service - Monthly
Severe Service - Daily to Monthly
Check chain and attachments for wear, nicks, cracks,
breaks, gouges, stretch, bend, weld splatter, discoloration from
excessive temperature, and throat openings of hooks.
1. Chain links and attachments should hinge freely to
adjacent links.
2. Latches on hooks, if present, should hinge freely and
seat properly without evidence of permanent distortion.
PERIODIC INSPECTION - INSPECTION
RECORDS REQUIRED
Normal Service - Yearly
Severe Service - Monthly
This inspection shall include everything in a frequent inspection plus each link and end attachment shall be examined
individually, taking care to expose inner link surfaces of the
chain and chain attachments.
1. Worn links should not exceed values given in table 1 or
recommended by the manufacturer.
2. Sharp transverse nicks and gouges should be rounded
out by grinding and the depth of the grinding should
not exceed values in Table 1.
3. Hooks should be inspected in accordance with ANSI
B30.10.
4. If present, latches on hooks should seat properly,
rotate freely, and show no permanent distortion.
5. Chains use OSHA and ASME regulations and safety
information.

WARNING
Failure to use this load binder properly may result
in serious injury or even death to you or others.
Do not operate load binder while standing on the
load.
Move handle with caution. It may whip - Keep body
clear.
Keep yourself out of the path of the moving handle
and any loose chain laying on the handle.
You must be familiar with state and federal
regulations regarding size and number of chain
systems required for securing loads on trucks.
Always consider the safety of nearby workers as
well as yourself when using load binder.
While under tension, load binder must not bear
against an object, as this will cause side load.
Do not throw these instructions away. Keep them
close at hand and share them with any others who
use this load binder.
Do not use handle extender - see instructions.
Do not attempt to close or open the binder with more
than one person.

Hook load binder to chain so
you can operate it while standing on the ground. Position
load binder so its handle can
be pulled downward to tighten
chain (see photo). Be aware
of ice, snow, rain, oil, etc.
that can affect your footing.
Make certain your footing is
secure.
The Crosby Group, Inc. specifically recommends
AGAINST the use of a handle extender (cheater pipe).
If sufficient leverage cannot be obtained using the
lever type load binder by itself, a ratchet type binder
should be used.
If the above recommendation is disregarded and a
cheater pipe is used, it must closely fit the handle and
must slide down the handle until the handle projections
are contacted. The pipe should be secured to the
handle, for example, by a pin, so that the pipe cannot
fly off the handle if you loose control and let go.
The increased leverage, by using a cheater pipe, can
cause deformation and failure of the chain and load
binder.
During and after tightening chain, check load binder
handle position. Be sure it is in the locked position and
that its bottom side touches the chain link.
Chain tension may decrease due to load shifting during
transport. To be sure the load binder remains in proper
position: Secure handle to chain by wrapping the loose
end of chain around the handle and the tight chain, or
tie handle to chain with soft wire.
When releasing load binder, remember there is a great
deal of energy in the stretched chain. This will cause
the load binder handle to move very quickly with great
force when it is unlatched. Move handle with caution.
It may whip - Keep body clear.
Never use a cheater pipe or handle extender to
release handle. Use a steel bar and pry under the
handle and stay out of the path of handle as it moves
upward.
If you release the handle by hand, use an open hand
under the handle and push upward. Do not close your
hand around the handle. Always keep yourself out
of the path of the moving handle.

Position ratchet binder so it can be operated from the
ground.
Make sure your footing is secure.

Maintenance of All Load Binders.
Routinely check load binders for wear, bending,
cracks, nicks, or gouges. If bending or cracks are
present - Do not use load binder.
Routinely lubricate pivot and swivel points of Lever
Binders, and pawl part and screw threads of Ratchet
Binders to extend product life and reduce friction wear.

Important Safety Information Read and Follow
A visual periodic inspection for cracks, nicks, wear,
gouges and deformation as part of a comprehensive
documented inspection program, should be conducted by trained personnel in compliance with the
schedule in ANSI B30.10.
For hooks used in frequent load cycles or pulsating
load, the hook and threads should be periodically
inspected by Magnetic Particle or Dye Penetrant.
(Note: Some disassembly may be required.)
Never use a hook whose throat opening has been
increased, or whose tip has been bent or twisted.
Never use a hook that is worn beyond the limits shown
in Figure 1.
Remove from service any hook with a crack, nick, or
gouge. Hooks with a crack, nick, or gouge shall be
repaired by grinding lengthwise, following the contour
of the hook, provided that the reduced dimension is
within the limits shown in Figure 1.
Never repair, alter, rework, or reshape a hook by
welding, heating, burning, or bending.
Never side load, back load or tip load a hook. Side
loading, back loading and tip loading are conditions
that damage and reduce the capacity of the hook.
(See Figure 2).

WARNING
Loads may disengage from hook if proper
procedures are not followed.
A falling load may cause serious injury or
death.
Never use hook unless hook and latch are fully
closed and locked.
Keep body parts clear of pinch point between
hook tip and hook latch when closing.
Do not use hook tip for lifting.
Shank threads may corrode and/or strip and
drop the load.
Remove nut securement to inspect or to
replace S-326A bearing washers (2).
Never apply more force than the hook’s
assigned Working Load Limit (WLL) rating.
See OSHA Rule 1926.550 (g) for personnel
hoisting by cranes or derricks. A Crosby 316A,
317A, 318A, 326A, 1316A, or 1317A hook may
be used for lifting personnel.
Use on ly g enuine Crosby parts as
replacements.
Read and understand these instructions before
using hook.

Efficiency of synthetic sling material may be reduced
when used in eye or bowl of hook.
Always make sure the hook supports the load. (See
Figure 3).
Do not use hook tip for lifting (See Figure 4).
When placing two (2) sling legs in hook, make sure
the angle from vertical to the leg nearest the hook tip
is not greater than 45 degrees, and the included angle
between the legs does not exceed 90 degrees* (See
Figure 5).
See ANSI/ASME B30.10 “Hooks” for additional
information.

•

* For two legged slings with angles greater than 90°, use an intermediate
link such as a master link or bolt type shackle to collect the legs of the
slings. The intermediate link can then be placed over the hook to provide
an in-line load on the hook. This approach must also be used when using
slings with three or more legs.

Important Basic Machining and Thread Information Read and Follow
Wrong thread and/or shank size can cause stripping
and loss of load.
The maximum diameter is the largest diameter, after
cleanup, that could be expected after allowing for
straightness, pits, etc.
All threads must be Class 2 or better.
The minimum thread length engaged in the nut should
not be less than one (1) thread diameter.
Hook shanks are not intended to be swaged on wire
rope or rod.
Hook shanks are not intended to be drilled and internally threaded.
Crosby cannot assume responsibility for, (A) the quality of machining, (B) the type of application, or (C) the
means of attachment to the power source or load.
Consult the Crosby Hook Identification & Working
Load Limit Chart (See below) for the minimum thread
size for assigned Working Load Limits (WLL).†
