Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As illustrated in figs. ia and ib, a kind of slab fan-shaped section of the present invention compound type changes suspender, comprises the chain-type suspender 2 for lifting fan-shaped section 3, for connecting the auxiliary lifting appliance 1 of overhead traveling crane plate hook and chain-type suspender 2; The connection suspension centre that compound type changes suspender and overhead traveling crane plate hook has two, with " A " mark.The connection suspension centre that compound type changes suspender and overhead traveling crane auxiliary hook has one, with " B " mark.Auxiliary lifting appliance 1 has two with the point of connection of chain-type suspender 2, with " C " mark.
As shown in Figure 2 a and 2 b, described auxiliary lifting appliance 1 comprises auxiliary lifting appliance beam 5, and be welded to connect a pair hanging axis 4 for connecting overhead traveling crane plate hook in auxiliary lifting appliance beam 5 upper end, assembly connection is at the auxiliary suspension hook 6 of auxiliary lifting appliance beam 5 lower end.
