(2) Working conditions
In case of the following working conditions, reduce the working load limit to 80% to use the chain
sling.
Multiply the actual load by 1.25 to select.
▪ Work that is carried out with high frequency or when the working load is applied continuously
▪ Work in which vibration is applied continuously
▪ Usage by incorporation in an automatic line
(3) When the chain comes into contact with the corner Contact with sharp edge during direct slinging
When the corner radius of the suspended load is smaller than the chain diameter,
be sure to apply a pad and reduce the working load limit to 70%
Multiply the actual load by 1.43 to select.
■ When using the chain sling in a high-temperature environment and the corner radius of the
suspended load is smaller than the chain diameter, multiply by respective increase rates to reduce
the working load limit.
<Selection example>
Select the chain size, naming as an example the standard sling type mentioned in the catalog.
(See the catalog for the outer shape of the sling.)
Standard sling type: Double-leg sling D-VD-VSN Slinging with hooks, double legs
Actual load: 2.5 t
Angle of loading: 90°
Ambient temperature: Normal temperature
High-frequency use: Multiply the actual load by 1.25 2.5 x 1.25 = 3.125 t

2-2 Preparing the Components (Hook, Fitting, etc.)
■ Select the top and bottom fittings based on the chain diameter and number of chain legs in line with
the customer’s order specifications.
■ In case of the standard sling type in the catalog, select the required components, seeing
“Chapter 4. List of Required Chain Length and Required Components for Standard Sling
Types”.
■ A chain pin kit is enclosed in the same package as the fittings and hooks.
<Selection example> In case of the standard sling type, type D-VD-VSS/Q-VD-VSS/Q-HM-HTS, chain
diameter = 8 mm
(See the catalog for the outer shape of the sling.)
Clevis-type D-VD-VSN Clevis-type Q-VD-VSN Eye-type Q-HM-HTN
2-3 Determining the Chain Length
Cut the chain with a high-speed cutting machine or a chain cutter.
2-3-1 Calculating the Standard Sling Type
■ See “Chapter 4. List of Required Chain Length and Required Components for Standard
Sling Types”.
See the catalog for the P-dimension of the fittings components.
(1) Clevis type
Reach L dimension – Top fitting P dimension – Bottom fitting P dimension = Required chain length
Required chain length / Selected chain pitch = No. of links
<Selection example> In case of type S-VE-V, chain diameter = 6 mm, reach L = 2.0 m
2000 – 115 – 115 = 1770 mm
1770/18.0 = 98.3 links No. of required links = 99
▪ Round up the chain length so that it will not be shorter than
the reach L dimension.
▪ For the sum of P dimension of the fittings components and the chain pitch, see “Chapter 4. List of
Required Chain Length and Required Components for Standard Sling Types”.

<Selection example> In case of type S-HM-HM, chain diameter = 6 mm, reach L = 2.0 m
2000 – 110 – 48 – 48 – 110 = 1684 mm
1684/18.0 = 93.5 links No. of required links = 95
▪ Round up the chain length so that it will not be shorter
than the reach L dimension.
▪ The number of required links is 94 according to the calculation result, 95 of them are required so
as to direct the top and bottom fittings as shown in the figure.
▪ For the sum of P dimension of the fittings components and the chain pitch, see “Chapter 4. List of
Required Chain Length and Required Components for Standard Sling Types”.
For the endless type slings (D-VD-OO、Q-VD-OO、D-HM-OO、Q-HM-OO), determine
the chain length so that the number of chain links will be always odd. Even links
causes a twist of chain, possibly lowering the chain strength and compromising
safe use of chain.
(3) Odd links and even links versus direction of the bottom fitting
■ The bottom fitting is directed differently depending on the number of chain links, odd or even.
Note particularly when the direction of the bottom fitting is specified by the customer’s
specifications.
The fittings of the standard sling types shall be directed as shown in the catalog.

■ Drive the spring pin firmly into the fitting until it is fully
embedded.
(To facilitate work, it is recommended to insert the spring pin
in such a manner that it will not project into a chain pin hole in the fitting.)
■ In case of the endless type (D-VD-OO and Q-VD-OO), set the
chain length so that the number of links will be odd, check for
any twist of chain, and assemble.
After assembly, check again if the chain pin has
been inserted and spring pin has been driven
into until it has been fully embedded, if the
chain is free from twist, if the chain length is
the same, and so on.
