Description

Technical Field

[0001] This utility model relates to the field of elevator car technology, and in particular to an elevator car and its top plate structure. Background Technology

[0002] An elevator is a means of transportation used for vertically transporting people or goods, and it is typically installed in public places. Existing freight elevators are larger than ordinary passenger elevators in order to accommodate more cargo. Compared to ordinary passenger elevators, due to their wider width, their roof slabs use thicker materials and more reinforcing ribs to ensure roof strength.

[0003] The above-mentioned freight elevator top plate has the following disadvantages: (1) After the thickness and width are increased, the number of reinforcing ribs needs to be increased in order to ensure the structural strength, which leads to an increase in production costs; (2) The top plate has a large size and a lot of matching installation parts, which increases the difficulty of transportation; (3) Due to the large size of the top plate, accidents are likely to occur during transportation, damaging the structure of the top plate. Utility Model Content
