(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-VE, 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 links 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 5. List of Required Chain Length and
Required Components for assembled products”.
(2) Eye type
Reach L dimension – Top fitting P dimension – Hi-coupling P dimension – Hi-coupling 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-HMM-HMM, 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 links so that it will not be shorter than
the reach L dimension.
・
The number of required links is 94 according to the calculation result, however, 95 links 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 5. List of
Required Chain Length and Required Components for assembled products”.
CAUTION
For the endless type slings (D-VD-OO, Q-VD-OO, D-HMM-OO, Q-HMM-OO),
determine the chain length so that the number of chain links will be always odd.
Even links causes a twist 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 assembled products shall be directed as shown in the catalog.
