Sling body and combined stacking sling using sling bodies

Abstract

The invention relates to a sling body and a combined stacking sling using sling bodies. The combined stacking sling comprises at least two mutually-stacked sling bodies. Each sling body comprises a main frame, wherein the main frame comprises at least one frame unit. Each frame unit comprises a bottom frame, a front vertical frame and a rear vertical frame, wherein the front vertical frame and the rear vertical frame are connected to the front side and the rear side of the bottom frame, and containing space for containing goods is jointly defined by the bottom frame, the front vertical frame and the rear vertical frame. Flying rings are arranged at the upper portion of each frame unit, the positions, vertically corresponding to the corresponding flying rings, of the lower portion of each frame unit are provided with lifting lugs in hanging fit with the flying rings on the corresponding frame unit of the lower side adjacent sling body. The sling bodies are made into same standard sling modules which can be freely stacked and combined within the bearing range, the structure is compact, and stacking is standard. Connection between the sling bodies is achieved through a mutual hanging and connecting manner of the lifting lugs and the flying rings, the structure is simple, connection is convenient, and rapid stacking and multi-manner combined hoisting of goods can be achieved. The goods are fixed and held through frames; and compared with traditional ropes and other hoisting processes, more safety and reliability are achieved.

Description

technical field [0001] The invention relates to a sling and a combined stacking sling using the sling. Background technique [0002] In the process of storage, transportation, and turnover of large (heavy) goods, such as long-length and heavy cylindrical goods that are hoisted in a box, and only one crane is used to fix and lift them from a certain point, the goods may be affected by the center of gravity. Unsteady and overturned, the goods cannot be hoisted safely, and more than two cranes are required to lift synchronously. This method has high requirements on the synchronization of the operation of the two cranes, and a little careless operation may cause major safety accidents. In addition , when the number of these goods is large, the efficiency of lifting the goods one by one is too low. If the goods are stacked together and lifted by slings, there will be a risk of the goods slipping and falling. Therefore, a joint lifting method is required. , A combined spreader th...
