Description

Technical Field

[0001] The utility model relates to the technical field of building tools, in particular to a multifunctional foldable transport vehicle. Background Art

[0002] This section introduces the background technology that may be related to various aspects of the embodiments of the present utility model to the readers, and is believed to provide the readers with useful background information, thereby helping the readers to better understand various aspects of the embodiments of the present utility model. Therefore, it can be understood that the description in this section is used for the above purpose and does not constitute an admission of the prior art.

[0003] With the continuous development of the national economy, the construction industry is an important part of the national economic growth. At the same time, with the improvement of people's living standards, the quality requirements for home decoration are getting higher and higher. In the process of indoor and outdoor construction and decoration, the materials and equipment required for construction are diverse. In addition, during the decoration process, construction workers often frequently perform high-altitude operations. In order to facilitate the operation, they often need to use some auxiliary tools such as scaffolding and ladders for high-altitude operations. Sometimes you need to stand on the pedals of a stepladder to work, and carrying various ladders adds unnecessary trouble to the workers.

[0004] At the same time, a large amount of garbage is generated during the construction process, which needs to be transported by transport vehicles. During decoration, a variety of materials also need to be transported, but the handrails of traditional transport equipment are fixed and cannot be folded, which will take up a large space during transportation, making it inconvenient to carry to higher floors for use.

[0005] In addition, during the workers' rest period, the construction site cannot provide a convenient resting place, and the workers can only sit or even sleep on the ground, which poses a huge threat to the workers' lives and health. The folding ladders currently on the market have no other functions after being folded, and the functions are too single. The above problems cannot be solved, and it is impossible to provide workers with a handy tool, which seriously affects the workers' work efficiency. Utility Model Content
