Description

Technical Field

[0001] The utility model relates to an anti-closing and anti-falling device for a material handling elevator in building construction. Background Art

[0002] As people's living standards improve, housing demand is also increasing, and real estate construction is also booming everywhere. During house construction, elevators are usually used to transport materials in high-rise construction. Before the house is fully built, composite panels are generally used to wrap the interior of the elevator as a whole to prevent scratches or collision damage caused by contact with the elevator's interior surface when transporting objects.

[0003] Usually, construction workers will carry objects into the elevator multiple times, trying to carry as much material as possible. At this time, the elevator will automatically close when there is no one supervising it, which will affect the workers' efficiency in carrying materials. In addition, some smaller materials may fall into the elevator shaft through the gaps in the elevator when the workers are carrying materials, and they are difficult to clean up. This situation may affect the operation of the elevator and thus affect construction safety. Utility Model Content
