Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a fully reusable self-closing construction elevator protection system. Background Technology

[0002] Construction elevators are often called construction hoists, but the definition of construction hoists is broader. Construction platforms also belong to the construction hoist series. A simple construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a type of construction machinery that is frequently used in construction to carry people and goods. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites.

[0003] In the current technology, with the vigorous development of the national economy, the scale of infrastructure construction is enormous, the supply of land resources is tight, and building projects are developing towards high-rise and super high-rise buildings, which brings great safety hazards. In order to ensure the safety of construction workers, facilitate installation and dismantling, reduce construction costs, improve resource utilization, and save materials, it is a very important link.

[0004] However, the protective grille and perforated mesh are fixed together with rivets, which limits the staff's ability to observe the actual situation inside the elevator. Summary of the Invention
