Effect of the distance between primary pivots on the stability of two-chain cargo suspension arrangement

Abstract The effect of distance between the primary pivots on stability two-chain suspension arrangement a load has been explored. Based concept and methodology for calculating static stability, developed in previous works, it shown that with narrow placement is generally less stable than normal arrangement. reduced such system primarily associated decrease length base triangle (ST) inside which gravity center (GCL) must be positioned. minimal provides equal to both arrangements (with pivots) also determined. An analytical inequality obtained, allowed us develop decision rule answer question whether same as system. It geometric dimensions systems weight load, fulfillment decisive (rule) depends mass spreader. wide position Nevertheless, since longer spreader usually heavier one then will more
