FLOATING CRANE AND MULTIFUNCTIONAL SUSPENSION HOOK AND MULTIFUNCTIONAL SUSPENSION HOOK GROUP THEREOF

摘要

A floating crane and a multifunctional suspension hook and a multifunctional suspension hook group thereof are disclosed. The multifunctional suspension hook comprises a fixed pulley group (10), a movable pulley group (20), a guide pulley group (30), a suspension hook (50) and a wire rope (60). The fixed pulley group (10) can swing vertically round the first shaft pin (11) on its axis. The guide pulley group (30) can swing horizontally round the second shaft pin (31) on its axis. The movable pulley group (20) is arranged below the fixed pulley group (10). The suspension hook (50) is mounted at the lower end of the movable pulley group (20). The wire rope (60) winds the guide pulley group (30), the movable pulley group (20), the fixed pulley group (10), the movable pulley group (20) and the guide pulley group (30) in sequence. The multifunctional suspension hook can realize horizontal swing and vertical swing in a hoisting plane. The multifunctional suspension hook group consisting of two such kind of multifunctional suspension hooks is used in the floating crane, thereby realizing turning over of the large structural piece, and having the advantages of simple assembly and few hook changes. Without the auxiliary hanging beams the hoisting work is more convenient and efficient.
