Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and in particular to an elevator suitable for narrow spaces. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, also known as a vertical elevator. A vertical elevator is equipped with a box-shaped pod and is used to carry people or goods in multi-story buildings. Elevators also have stepped types, with treads mounted on tracks for continuous operation, commonly known as automatic elevators, also known as escalators, pedestrian elevators, and handrails. An elevator is a fixed lifting equipment that serves specified floors. It runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15°. It has a car whose size and structure facilitate passenger entry and exit or loading and unloading of goods.

[0003] At present, the market demand for installing elevators in old residential buildings is becoming more and more urgent. However, since the need for elevator installation was not taken into account when the buildings were designed in the past, the shaft layout is a problem. The existing conventional elevator structure has a square structure and a reasonable layout of components. It meets the shaft layout requirements stipulated by building codes, but cannot meet the requirements of narrow shafts, resulting in the elevator door being unable to open and users being unable to enter and exit normally.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
