[0002] Prefabricated building is a kind of building mode, which is to transport the prefabricated components such as wallboard, floor, beam column etc. to the construction site for assembly after being prefabricated in factory. In the prefabricated building construction process, hoisting operation is the key link of hoisting prefabricated components from transport vehicle or stacking site to designated installation position. Since prefabricated components are usually large in size and heavy in weight, and high installation accuracy is required, efficient and safe hoisting operation must be carried out by hoisting equipment such as tower crane, truck crane etc.

[0003] The existing prefabricated building construction hoisting device (announcement number: CN222118640U) has at least the following disadvantages: although the above device relies on two clamping jaws to clamp and fix the components during hoisting, when the clamping jaws fix the components, only clamping force is applied to the left and right sides of the components, and the front and rear sides lack effective limiting. If the length of the component exceeds the range of the hoisting yoke and the center of gravity is not located at the center of the hoisting yoke, the component is easy to tilt and slip between the two clamping jaws during lifting, which affects the stability of hoisting and weakens the overall hoisting effect. Therefore, we propose the utility model. UTILITY MODEL CONTENT
