[0002] The existing machine-room-less elevator technology has the following problems:

[0003] (1) Installation limitations of traction machines: Traditional traction machines are mostly fixed to the top load-bearing beam of the elevator shaft, which requires additional structural reinforcement, resulting in low space utilization of the elevator shaft and high installation complexity.

[0004] (2) Difficult maintenance of rope end assembly: The car rope end assembly is usually fixed to the elevator shaft wall by an independent bracket. The installation accuracy is high and the subsequent maintenance requires frequent adjustments, which is inefficient.

[0005] (3) Redundancy in speed governor layout: The speed governor needs to be supported separately, which occupies the elevator shaft space and lacks coordinated design with the guide rail system, resulting in insufficient dynamic response stability.

[0006] To address the aforementioned issues, there is an urgent need for a highly integrated and modular installation solution to optimize spatial layout and improve maintenance efficiency. Utility Model Content
