Load spectrum and duty group

Edit how often each load is lifted and watch the cube law decide the fatigue: k_p and the spectrum class.

Try it: load spectrum and fatigue

Lifts at 20 % of rated60 %

Lifts at 40 % of rated20 %

Lifts at 60 % of rated10 %

Lifts at 80 % of rated7 %

Lifts at 100 % of rated3 %

k_p = Σ (n_i / N) (P_i / P_max)³
