Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a machine room-less freight elevator arrangement structure. Background Art

[0002] As a form of public transportation, elevators can transport people quickly and accurately to their destinations, avoiding time wasted and congestion caused by human error. Due to limited urban space, buildings are growing taller and taller. The advent of elevators has made high-rise access accessible to more people while also reducing floor space and the cost of staircases, which are not the safest means of transportation in high-rise buildings. Elevator designs incorporate various safety features, such as braking systems, automatic door openings, and emergency alarms. These features significantly enhance elevator safety. Machine-room-less elevators eliminate the need for a dedicated, enclosed machine room; instead, they require a maintenance platform beneath the main unit. This saves space, particularly in buildings where a machine room is inconvenient, such as podiums, guesthouses, and hotel annexes. Furthermore, the lack of a machine room reduces construction costs for owners, reducing both the construction and maintenance expenses of the machine room.
