The invention relates to a hoisting device (1) comprising two frame assemblies (2, 3) which lie one above the other with respect to the height direction (Z), in which frame assemblies the lower frame assembly (2) is suspended from the upper frame assembly (3) by means of lifting traction means (H1-H4) which can be wound by means of a lifting device (4). In order to stabilize the deflectable lower frame assembly (2) in a first lateral direction (R1), each of the lifting traction mechanisms (H1-H4) is reversed at least once in its extent, in this way, a diagonal section (H1d-H4d) of each lifting traction mechanism (H1-H4), said diagonal section extending in an inclined manner relative to the height direction (Z), intersects such a diagonal section (H1d-H4d) of another lifting traction mechanism (H1-H4), said diagonal section extending in an inclined manner directly adjacent to and opposite to the other lifting traction mechanism (H1-H4). According to the invention, tilting traction means (S1-S4), which can be wound by means of a tensioning device, extend between the two frame assemblies (2, 3), in which tilting traction means two directly adjacent tilting traction means (S1-S4) intersect one another such that the second frame assembly (3) is also stable with respect to the upper frame assembly (3) with respect to the second lateral direction (R2).
本发明涉及一种起重设备(1),包括两个关于高度方向(Z)相叠的框架组件(2,3),在框架组件中,下部框架组件(2)通过借助升降装置(4)可卷绕的升降牵引机构(H1‑H4)悬挂地设置在上部框架组件(3)上。为了沿第一侧向方向(R1)稳定可偏转的下部框架组件(2),升降牵引机构(H1‑H4)中的每个升降牵引机构在其延伸范围中至少一次换向,使得每个升降牵引机构(H1‑H4)的由此相对于高度方向(Z)倾斜延伸的对角区段(H1d‑H4d)与另一个升降牵引机构(H1‑H4)的直接相邻的并且相反地倾斜延伸的这样的对角区段(H1d‑H4d)相交。按照本发明,借助张紧装置可卷绕的倾斜牵引机构(S1‑S4)在两个框架组件(2,3)之间延伸,在倾斜牵引机构中,分别两个直接相邻的倾斜牵引机构(S1‑S4)彼此相交,使得第二框架组件(3)也关于第二侧向方向(R2)相对于上部框架组件(3)稳定。
