As a vertical transportation vehicle, passenger elevators are divided into two types: machine room passenger elevators and machine roomless passenger elevators according to the installation position of the traction drive device. The machine roomless elevator is relative to the machine room elevator, that is to say, the equipment in the machine room is miniaturized as much as possible while maintaining the original performance by using modern production technology, eliminating the machine room, and the control cabinet in the original machine room, The traction machine, speed limiter, etc. are moved to the top of the elevator hoistway or the side of the hoistway, thereby eliminating the traditional machine room in order to meet the special requirements of customers for height and roof.

1. The advantages of machine-room-less elevators compared to machine-room elevators
2. Machine roomless elevator saves space
3. With more flexibility and convenience, and because of the cancellation of the machine room, for the owner, the construction cost of the machine room elevator is lower than that of the machine room elevator
4. The machine roomless elevator can solve the problem of elevator installation within the effective height because it is not necessary to set the main engine room of the elevator separately, which can effectively reduce the height of the building. At the same time, for places where it is not convenient to install elevator machine rooms, it can well alleviate the space problems of the building itself for installing elevators, such as the renovation and installation of old buildings.

Second, the disadvantages of machine roomless elevators compared to machine room elevators

1. In terms of noise, the machine roomless elevator is obviously larger than the machine-room elevator.
2. The comfort of the machine roomless elevator is obviously weaker than that of the machine room.
3. The limitation of the elevator without machine room to elevator speed. Machine roomless elevators are not suitable for high-speed elevators above 1.75m/s.
4. The load capacity of elevators with machine rooms is also significantly better than elevators with machine rooms.
5. The heat dissipation function of machine roomless elevators is worse than that of machine room elevators. In particular, the fully transparent sightseeing elevator is not suitable for the installation of machine roomless elevators. In summer, the heat accumulated in the elevator cannot be discharged, and elevator failures increase.
6. The maintenance and management of machine roomless elevators are not as convenient as machine-room elevators. In terms of maintenance and management, the machine room elevator occupies an absolute advantage, which is convenient for daily inspections and maintenance and can intuitively find problems.

Third, it is even more prosperous in terms of personnel rescue.

Because machine rooms are mostly used for low-speed ladders in lower buildings, rescuers have obvious advantages when climbing stairs when people are trapped. The machine room elevator is more reliable than the machine room elevator when the brake is released for rescue.

  Through comprehensive comparison and analysis of various aspects, the advantages and disadvantages of machine roomless elevators and machine room elevators are different. When choosing elevators, you should choose machine roomless passenger elevators or elevators with machine room passenger elevators according to actual needs.
