The invention relates to the technical field of engineering machinery, and provides a lifting appliance and hoisting machine.The lifting appliance comprises a middle cross beam provided with a first connecting part used for being connected with the hoisting machinery; the two side cross beam assemblies are rotationally connected with the two ends of the middle cross beam correspondingly, the two side cross beam assemblies can be switched between a first relative position and a second relative position, in the first relative position, the axes of the two side cross beam assemblies coincide with the axis of the middle cross beam, and in the second relative position, the axes of the two side cross beam assemblies coincide with the axis of the middle cross beam. The two side cross beam assemblies are located on the two sides of the axis of the middle cross beam correspondingly, the included angles between the axes of the two side cross beam assemblies and the axis of the middle cross beam are equal, and the ends, away from the middle cross beam, of the side cross beam assemblies are provided with second connecting parts used for being connected with heavy objects. By means of the arrangement, the length size of the lifting appliance in the folded state is reduced, the gravity center position is stable, and the problems that in the prior art, a foldable lifting appliance is large in length size and unstable in gravity center position in the folded state are solved.
本发明涉及工程机械技术领域,提供一种吊具及起重机械,其中,吊具包括中间横梁,设置有用于与起重机械连接的第一连接部;两个侧横梁组件,分别与中间横梁的两端转动连接,两个侧横梁组件能够在第一相对位置与第二相对位置之间切换,在第一相对位置,两个侧横梁组件的轴线与中间横梁的轴线重合,在第二相对位置,两个侧横梁组件分别位于中间横梁的轴线的两侧且两个侧横梁组件的轴线与中间横梁的轴线之间的夹角相等,侧横梁组件远离中间横梁的一端设置有用于与重物连接的第二连接部。如此设置,减小了吊具在折叠状态时的长度尺寸,重心位置稳定,解决了现有技术中的可折叠吊具存在的在折叠状态时长度尺寸较大、重心位置不稳的问题。
