4. Assembly Procedures
Wrong assembly may result in death or serious injury.
Observe the assembly procedures to assemble the chain sling correctly.
4-1 Clevis Type
4-1-1 Assembly
A removed spring pin is not reusable.
■
Check if all the constituent components are included.
■
Use the chain pins and spring pins which are
accompanying the fittings and hooks.
■
Check the types of the replacement chain pins and
spring pins (chain pin kit) and use the conforming
ones.
■
In case of the double, triple and quadruple legs,
check if each chain length has the same length.
■
During work, care should be taken not to damage
coating of the fittings, etc.
■
Arrange the components on the workbench and
connect the chain and fitting with the chain pin.
■
Ensure that the weld area of the links at both ends of
the chain to be assembled into the fitting assembly
are set in the same direction as other links.
■
Drive the spring pin firmly into the fitting until it is fully
embedded.
(To facilitate work, it is recommended to insert the
spring pin beforehand 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.
4-1-2 Marking on the Sling Tag
Upon receiving an order, be sure to check the slinging method, No. of chain legs
and fittings type
, clearly mark the working load limit on the sling tag
.
■
Two types of sling tags are available; one for single leg and the other for double, triple and
quadruple legs. (See Page 8.)
1. Sling tag for single leg: Mark the chain diameter, working load limit, and manufacture date.
2. Sling tag for double, triple and quadruple legs: Mark the chain diameter, working load limit
60º, working load limit 90º, working load limit 120º, No. of chain legs, and manufacture date.
