Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering lifting devices, in particular to a construction engineering machinery lifting device. Background Art

[0002] During the construction process of a building project, building materials often need to be lifted to a high place. The lifting lug is a load-bearing component installed on the equipment for lifting. It is a device used to lift heavy objects. The lifting lug is hung on the crane hook and moved by the crane.

[0003] The lifting ear in the prior art has a simple structure. When lifting building materials, usually only two steel wire ropes are passed through the lifting ear to fix or tie to the building materials. Due to the lifting method of the two ropes, the force points are very concentrated, which may cause the lifting ear and the rope to be subjected to excessive pressure when lifting heavy objects, which may easily cause local wear and even damage. For example, when lifting heavy metal components, the concentrated force may cause cracks in the lifting ear. Secondly, since there are only two force points, for goods with irregular shapes or uneven center of gravity, the goods are prone to tilting and shaking. For example, when lifting asymmetric large equipment, the balance may be lost due to the shift of the center of gravity. Therefore, it is necessary to design a lifting device for construction machinery to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a lifting device for construction engineering machinery.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
