Abstract

The invention discloses a lifting hook which comprises a left vertical plate (31) and a right vertical plate (32) and also comprises a hanger (37) connected between the left vertical plate (31) and the right vertical plate (32). The central section of the hanger (37) is provided with a wire rope interconnecting piece (371). When multiplying power of the lifting hook is odd number, a wire rope is connected on the wire rope interconnecting piece of the hanger. According to the above lifting hook, as the wire rope interconnecting piece is positioned at the central section of the hanger, that is to say, after the wire rope is connected with the hanger, active force applied on the lifting hook is applied at the central section of a poppethead such that stress of the poppethead tends to be balanced. Thus, a hook assembly is not easy to undergo side load stress so as to reduce hook assembly rupture probability caused by side load stress. The invention also discloses a crane including the above lifting hook.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a lifting hook. The invention also relates to a crane with the above-mentioned lifting hook. Background technique [0002] The lifting hook is one of the important working parts of the crane, such as figure 1 Shown, this lifting hook mainly comprises left vertical board 11, right vertical board 12, pulley shaft 13, hook pulley block 14, crossbeam 15 and suspension hook 16, and pulley shaft 13 and crossbeam 15 are all installed on left vertical board 11 and Between the right vertical boards 12, the hook pulley block 14 is sleeved on the pulley shaft 13, and the suspension hook 16 is hung on the crossbeam 15. [0003] like Figure 2-5 As shown, the above-mentioned lifting hook is often suspended on the wire rope of the hoisting mechanism 21 by means of the pulley block and other parts, and the wire rope is fixed after going around the arm head guide wheel 22, the m...
