With respect to the development of specific operating hours (i. e. hours per machine/appliance
and year, see Fig. 18), the graph shows a sharp increase (70%) for
construction machines, from 230 hrs p.a. in 1980 to 390 in 2020. By contrast, a reduction
in average operating hours by 29% is anticipated for agricultural machinery, from
140 hrs p.a. in 1980 to 100 in 2020.
Figure 19 shows the development of operating hours by engine-power class for all
diesel-powered non-road machines. The picture is similar to that for the development
of inventories by engine-power class (Fig. 14). The structural changes (trend towards
more powerful machines) are more apparent than is the case for inventories. The total
operating hours of machines with an engine power between 130 and 300 kW, the
inventory of which quadruples in the period from 1980 to 2020, increase by a factor of
5.6 during the same period.
