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

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.

*   Check the suspension bracket. See Checking the suspension bracket.

*   Check the condition of the chain. See Inspecting the condition.

*   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.

*   Check the installation of the chain.
It should 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 next to last 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.

*   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.
