Research on Energy-Saving Design of Overhead Travelling Crane Camber Based on Probability Load Distribution

Table 1

Load status level and corresponding load spectrum coefficient.

Load status levels	Load spectrum coefficient of crane, 𝐾𝑝	Work conditions
𝑄1	𝐾𝑝 ≤ 0.125	Seldom for rated load and often light load
𝑄2	0.125 < 𝐾𝑝 ≤ 0.250	Seldom for rated load and often medium load
𝑄3	0.250 < 𝐾𝑝 ≤ 0.500	Sometimes for rated load and often heavy load
𝑄4	0.500 < 𝐾𝑝 ≤ 1.000	Often for rated load
