The invention relates to the technical field of lifting, in particular to a lifting appliance which comprises a main force bearing rod, a telescopic rod and a first lifting rope, and a main lifting point is arranged at one end of the main force bearing rod; the telescopic rods are circumferentially arranged on the main force bearing rod, one end of each telescopic rod is hinged to the main force bearing rod, the other end of each telescopic rod is provided with a branch lifting point, and the length of each telescopic rod is adjustable; one end of the first lifting rope is connected with one end, far away from the main bearing rod, of the telescopic rod, and the other end of the first lifting rope is connected with one end, close to the main lifting point, of the main bearing rod. When the lifting appliance is used, the main force bearing rod, the telescopic rod and the first lifting rope form a stable triangular structure, when the lifting appliance faces to-be-lifted heavy objects with different sizes, the distance between the branch lifting points located on the telescopic rod and the main lifting point located on the main force bearing rod can be adjusted by adjusting the length of the telescopic rod, and the application range of the whole lifting appliance is widened.

    本发明涉及吊装技术领域,尤其涉及一种吊具,该吊具包括主承力杆、伸缩杆以及第一吊绳,主承力杆的一端设置有总吊点;伸缩杆的数量为多个且周向设置于主承力杆,伸缩杆的一端与主承力杆铰接,另一端设置有分吊点,伸缩杆的长度可调;第一吊绳与伸缩杆一一对应,第一吊绳一端与伸缩杆远离主承力杆的一端连接,另一端与主承力杆靠近总吊点的一端连接。上述吊具使用时,主承力杆、伸缩杆以及第一吊绳形成一个稳定的三角结构,在面对不同尺寸的待吊重物时,通过调节伸缩杆的长度,可以实现位于伸缩杆上的分吊点与位于主承力杆上的总吊点的间距调节,扩大了整个吊具的适用范围。
