The invention describes a lifting rigging (1) comprising: a yoke (10) adapted to be connected between a load (3) and a suspension point (20); and a load bearing assembly (14) mounted on the yoke (10), the load bearing assembly (14) comprising: a spring module (140) comprising a plurality of constant torque springs (14S); and a yoke wire (141) having a first end and a second end, the first end being adapted to be connected to the suspension point (20), the second end being connected to the spring module (140) and being adapted to wind the constant torque spring (14S) when the yoke wire (141) is subjected to a tensile force (Fpull), and wherein the yoke wire (141) has a first end adapted to be connected to the suspension point (20) and a second end adapted to be wound around the constant torque spring (14S) when the yoke wire (141) is subjected to a tensile force (Fpull). The load-bearing assembly (14) is configured such that the yoke wire (141) bears the weight of the yoke (10) when the lifting rigging (1) is suspended from the suspension point (20).
本发明描述了一种提升索具(1),其包括:轭架(10),其适于连接在负载(3)和悬挂点(20)之间;以及安装在所述轭架(10)上的承重组件(14),所述承重组件(14)包括:弹簧模块(140),其包括多个恒扭矩弹簧(14S);以及轭架线(141),其具有第一端和第二端,所述第一端适于连接到所述悬挂点(20),所述第二端连接到所述弹簧模块(140),并且适于在所述轭架线(141)经受拉力(Fpull)时卷绕所述恒扭矩弹簧(14S),并且其中,所述承重组件(14)被构造成使得当所述提升索具(1)从所述悬挂点(20)悬挂时,所述轭架线(141)承受所述轭架(10)的重量。
