The qualified person inspecting the drive is responsible for the type and scope of the test.

In addition to the points described here, all points outlined in the other supplied product manuals must also be checked.

The decision as to whether the drive is in perfect condition may be made only by the person inspecting the crane. Any inadequacies, if found, must be eliminated. The examiner decides whether the drive has to be tested again afterward.

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 air gap and the brake lining thickness. See Checking the air gap and brake lining thickness.

   Check the lubrication of the gear rims. The gear rims must be lubricated over their entirety. The lubricant should be clean. If it is dirty, clean the gear rims and lubricate them. See Lubricating the gear rim.

   Check the gear rims. The gear rims should not be worn, deformed or otherwise damaged. If they are, replace the wheels.
