SCOPE OF THE TEST
The qualified person inspecting the chain hoist is
responsible for the type and scope of the test.
OVERVIEW: TESTING THE CHAIN
HOIST
In addition to the points described here, all points
outlined in the other supplied product manuals must
also be checked.
The decision regarding the technically faultless
condition of the chain hoist lies solely with the
examiner. Any inadequacies, if found, must be
eliminated. The examiner will decide if the chain hoist
then requires additional testing.
If locally applicable regulations specify further tests,
these are likewise to be carried out.
Additionally, at least the following points must be
checked:
Check the load hook. See “Checking the load
hook”, page 32.
Check the suspension bracket. See “Checking
the suspension bracket”, page 32.
Check the condition of the chain. See
“Checking the condition of the chain”, page 33
and “Checking the wear on the chain”,
page 34.
Check the friction clutch. See “Checking the
friction clutch”, page 35.
Check the air gap and brake lining thickness.
See “Checking the brake on the chain hoist”,
page 36.
Check the lubrication of the chain. The chain
may not be dry; lubricant must be visible on its
surface. If it is not, lubricate the chain. See
“Lubricating the chain”, page 65.
Check the installation of the chain. It may not
be installed twisted. If it is, remove the chain
and reinstall it so that it is free of any twisting.
Check the C-link. It must be present and
attached to the penultimate or third-last chain
link in such a way that the opening, when
installed, points in the direction of the inner fall
(the fall under load). Otherwise, reinstall the C-
link.
Check the chain anchor point. The bolt must be
inserted and secured. If it is not, push the bolt
in and secure it with the SL safety clip.
Test the deep groove ball thrust bearing on the
load hook. It must turn easily and exhibit no
damage. Otherwise, replace the deep groove
ball thrust bearing.
Document the test:
If the chain hoist is part of a crane installation:
Document the results of the test in the test log
book of the crane installation.
If the chain hoist is operated independently:
Document the results of the test in the test log
book. See “Test log book”, page 39.
