The actual hours of use (S) must be documented within the scope of a regular inspection at least once yearly.

The remaining service life will continue to be evaluated during the regular inspection. This is done by determining whether the actual hours of use (S) are still fewer than the number of hours representing the theoretical service life (D).

If the remaining service life is very limited or zero, the hoist may no longer be used. In this case, a general overhaul of the entire hoist by ABUS as manufacturer is required.

   The exact procedure for determining the remaining service life can be found in FEM 9.755.

Overview:

   The classification according to FEM for the hoist drive can be read on the type plate.

   Read the corresponding theoretical service life D in the table.

   Determine the actual hours of use.

This can be done using a load population recorder, an operating hours counter, through documentation of usage or by estimating.

   Compare the theoretical service life (D) and the determined actual hours of use (S).

   The calculated remaining service life of the hoist is to be be documented in the test log book.

   If the theoretical service life of the hoist has been reached: Take the hoist out of service and have ABUS perform a general overhaul.
