5.4 Measures required for winch monitoring

Also observe the information on the general inspection of the hoists;
à p. 8 - 13.
These measures for monitoring the winches (hoists) were compiled by the
German Machine Builde
rs' Association (VDMA) and are to be used for all
truck cranes according to the German
Accident Prevention Regulations for
Winches, Hoists and Tractor Machines, BGV D 6 (VGB 9
) and BGV D 8 (VBG 8).
5.4.1 Theoretical service life
The theoretical service life is determined according to certain operating
conditions and a theoretical total operating time assumed by the design
engineer when calculating and dimensioning the winches of your truck crane.
The power unit group M 3 and the load spectrum L1 (Km = 0.125) are
generally given for truck cranes in assembly
mode, resulting in a theoretical
service life of 3,200 hrs. (ISO 4301/1, FEM 1.001, DIN calculation basis for
power units).

The theoretical service life is not the same as the real (actual) service life
of a winch.
