Chain Sling Assembly
GRADE 80 CHAIN SLING ASSEMBLY
BASIC TYPES OF CHAIN SLINGS
Basic types of chain slings are dsignated throughout the
industry by the following symbols:
First Symbol (basic type):
S - Single chain sling with master link and hook, or hook at each end.
C - Choker chain sling with master link on each end; no hooks.
D - Double chain sling with standard master link and hooks.
T - Triple chain sling with standard master link and hooks
Q - Quadruple chain sling with master link and hooks.
Second Symbol (type of master link or end link):
O - Oblong master link – Recommended standard for all types.
P - Pear shaped master link – Available on request.
Third Symbol (type of hook):
S - Sling hook G - Grab hook
F - Foundry hook L - Latchlok hook
Sling tags are coded with numerals 1 through 4 to reflect number of branches
in sling. Additional coding is defined as follows:
AS - Adjustable sling SB - Single Basket
ES - Endless single ED - Endless double
SAL - Single adjustable loop DAL - Double adjustable loop
AD - Adjustable double DB - Double basket
HOW TO SELECT & ORDER THE PROPER CHAIN SLING
1. Determine the weight and configuration of the load(s) to be
lifted.
2. Determine the type of chain sling required, according to
weight and configuration. (refer to the following pages)
3. Determine the size of the body chain according to the
working load limits. Be sure to take into consideration the
effect of the required angle.
*Working load limit: The working load limit is the maximum
load in pounds which should ever be applied to chain, even
when chain is new, and when load is uniformly applied in
direct tension to a straight length of chain.
4. Determine the reach required to give the desired angle. The
reach is measured from the upper bearing surface of the
master link to the bearing surface of the lower attachment.
If chain slings are to be used in pairs and are to be matched
for reach, please indicate when ordering.
5. Be sure to specify type, size and reach when ordering chain
slings. For specifications on additional hooks, attachments
and accessories, refer to the following pages.
Note: Angle to the load on multiple leg slings will be 60° or
greater as long as the distance between lifting eyes of load
is NOT greater than reach shown on Identification Tag.
