Description

[Technical Field]

[0001] This invention relates to a lifting bag for efficiently and safely lifting scaffolding work floor materials such as antis (treads) and scaffolding planks. [Background technology]

[0002] At civil engineering sites, work involves unloading scaffolding work floor materials such as antis (treads) and scaffolding planks and assembling the scaffolding.

[0003] In the past, the typical method for lifting such loads was to tie the scaffolding work floor material with ropes and lift it using a hoist. However, lifting work with ropes takes time and requires the skill to handle the ropes, so workers are required to have high levels of skill.

[0004] Furthermore, although there are dedicated lifting devices that are attached to the end of a lifting wire, they have the problem that they can only be used with specific types of scaffolding work floor materials, i.e., specific types of antis. For example, there is a dedicated lifting device for antis made of mesh material, as described in Patent Document 1. Furthermore, there are dedicated lifting devices for antis with gaps, as described in Patent Documents 2 and 3.

[0005] These dedicated hoisting devices are designed for specific types of scaffolding work floor materials, and are therefore limited to specific uses. As a result, given the current situation in which a wide variety of materials are used at work sites and by different contractors, hoisting devices that can only be used for a limited number of types are problematic in terms of usability.

[0006] Furthermore, for scaffolding planks and anti-skid structures with no gaps between them, there are no compatible lifting devices, so workers usually have to rely on ropes to lift them, making it difficult to work efficiently. This situation has led to a demand for the development of a new lifting device that can be used with a wide range of scaffolding work floor materials and enables efficient lifting work.
