The following tests must be performed with care in order to avoid damage to the crane
or injury to personnel. Proper functioning of the LMI system requires successful com-
pletion of these tests before commencing work. If the operator cannot see the hook
block approaching the head machinery, he must assign this task to an assistant
(slinger). The crane operator must be prepared to stop the crane at once in the event
that the LMI system is not working correctly, i.e. when the red warning lights fail to
light up, the acoustic alarm does not sound and the crane movements such as raising,
extending and luffing are not switched off.

Check the

Hoist limit switch warning light

and the acoustic alarm as follows:

1. Manually raise the weight fitted on the hoist limit switch. As soon as the weight is raised, the acoustic

alarm should sound and the

hoist limit switch warning light

should light up.

If the warning light and the audible alarm do not function as described and the crane
movements are not switched off, then the system is not working properly. The mal-
function must be corrected before commencing work.

5. If the crane is equipped with a main boom extension or with a lattice extension, then the inspection

procedure must be repeated for the hoist limit switch of the extension/top section.

6. Check that the display of the main boom length agrees with the actual boom length.

7. Check that the display of the main boom angle agrees with the actual boom angle.

8. Check that the display of the operating radius of the crane agrees with the actual radius.

9. Check the load display by lifting a load of known weight. The accuracy of the load display must be

within the tolerance range.
