| Abstract: | In this study, two rotary support devices of floating cranes, i. e. bogie and multi-rows wheel types,are analyzed in terms of structural characteristics and loading distributions. Accordingly, the advan- tages and disadvantages are investigated. Afterwards, a new chain type wheel device is developed to overcome the existing structural problems, e. g. large loading and even wheel pressure. Eventually, these technologies are enabled upon rotary support device of ultra-large-scale floating cranes. |
