Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a 4:1 machine room layout structure applied to an ultra-large load freight elevator. Background Art

[0002] With the progress of society and the development of the economy, the market demand for large-load freight elevators is constantly increasing. However, the machine room structure of traditional freight elevators has limited bearing capacity, and is affected by the bearing capacity of the traction machine. The operating speed and load capacity of the freight elevator are both limited, which cannot meet the demand for large-load freight elevators.

[0003] Therefore, currently, increasing the load capacity of freight elevator systems typically involves using larger traction machines. However, as the size of the traction machine increases, its weight also increases. Therefore, in existing high-load freight elevators, the change in the size and weight of the traction machine makes the existing elevator machine room layout unsuitable for elevator operation. Therefore, rational improvements are needed for the layout of elevator machine rooms with a traction ratio of 4:1. Utility Model Content
