The used proportion S
2
of theoretical service life at the 2nd inspection is
therefore:
Remaining theoretical service life:
D2 = 3,040 h - 1,920 h = 1,120 h.
The aforementioned values are entered in the table (see table example
p. 5 - 28).
3rd inspection (3rd year)
The truck crane was used for assembly work and occasional unloading work
on docks: Load spectrum: L 2, i.e. Km
3
= 0.25.
he operating hours counter for the main hoist reads 940 h, i.e. during this
period: 940 h - 640 h = 300 h. T3 = 300 h.
The used proportion S
3
of theoretical service life at the 3rd inspection is
therefore:
Remaining theoretical service life:
D3 = 1,120 h - 600 h = 520 h.
The values are entered in the table
(see table example p. 5 - 28).
The remaining theoretical service life is to be documented in a separate
table for each winch.
This table is to be attached to the crane logbook. This table is to be found in
the maintenance manual's appendix for truck cranes that do not require a
crane logbook or similar documentation according to the regulations of the
respective country.
