What is an elevator with a machine room?

The machine room in the elevator is the area where the drive unit is located, including two circuit breakers, a control unit and a pump unit. These two circuit breakers play the role of providing power to the equipment and disconnecting the lights inside the elevator when necessary. The controller operates through a series of relays to activate elevator operation and is often considered the central "brain" of the system. The elevator's oil pump and motor are at the top, creating convenient conditions for technicians to control and periodically maintain.

Having a separate machine room makes it easier to control and maintain the elevator. Elevators with machine rooms often need to be equipped with ventilation to increase the ability to control the internal environment, thereby minimizing the risk of damage to the equipment. In addition, the installation of a ceiling lift bar and floor hatch provides easy and convenient access for machinery and heavy parts during maintenance and repairs. This ensures that the elevator can operate stably and efficiently over a long period of time.

What is an elevator without machine room?

Machine roomless elevators, also known as machine roomless elevators, are a type of elevator equipment specially designed with a separate machine room. The traction machine of a machine roomless elevator is usually placed on top of the car's guide rail and counterweight, facilitating operation and maintenance. Other equipment such as electrical cabinets and control cabinets are often placed on the side of the top floor door.

To ensure the safety and performance of the elevator, the top of the elevator shaft also needs to be specially designed. This includes the installation of 2 construction hangers and the design of ventilation holes to reduce the temperature of the tractor, thereby ensuring stable and efficient operation of the equipment.

Using machine roomless elevators not only brings convenience and safety in movement but also ensures the aesthetics and performance of the house or building. At the same time, appropriate design and installation also play an important role in optimizing space and related technical factors.

Advantages of elevators with machine rooms

The advantages of elevators with machine rooms are something that many people pay attention to and appreciate. The travel speed of elevators with machine rooms is usually higher and is recommended at greater than or equal to 1.75m/s. This is especially useful in high-rise buildings or commercial projects with the need to transport heavy goods, exceeding 1150kg.

This feature also comes with higher operating power of the elevator, helping to improve operating efficiency and load capacity. With a gear ratio of 1:1, elevators with machine rooms use shorter cables and fewer pulleys, thereby reducing maintenance costs and ensuring the maintenance process is simple and convenient.

In addition, the rescue plan also becomes more convenient and simpler in the event of a power outage, even when there is no rescue team that can promptly assist. This creates peace of mind and confidence for users about the safety and convenience of elevators with machine rooms.

Advantages of elevators without machine room

One of the top advantages of machine room-less elevators is the ability to save costs. Because they do not require installation space inside the building, they can be installed directly on the overhead hoist without the need for a separate machine room, thereby reducing structural load and construction costs. You can save up to 70% of electricity consumption compared to hydraulic elevators, thanks to the use of inverter drives and variable voltages. This also means reduced operating costs and saved installation costs, making machine roomless elevator quotes often lower than other types.

Machine roomless elevators do not use engine oil, eliminating the risk of fire and becoming more environmentally friendly. You can also customize them to your specific needs easily.

With the ability to carry 10 to 16 passengers and a load capacity of 680 to 1150kg, machine roomless elevators meet the transportation needs of many families and buildings. Using a gearless engine is considered safe, does not cause noise and vibration. Furthermore, they do not add any additional pressure to the building's static load, helping to protect the structure and increase the safety of the moving system.

Some disadvantages of elevators with machine rooms

Elevators with machine rooms require a separate room for the tractor, which results in the cost of building a machine room, increasing initial costs. Compared to elevators without machine rooms, elevators with machine rooms are often much cheaper, making them a popular choice for projects with limited budgets.

However, the operating mechanism of elevators with machine rooms is often not as smooth and the electricity efficiency is also lower than elevators without machine rooms. This makes the operation and maintenance costs of elevators with machine rooms higher in the long term.

In addition, elevators with machine rooms also face difficulty when installed in buildings with height restrictions, because the machine room often requires a special height (usually about 2200mm). At the same time, periodically changing gear oil can pollute the environment, which is another disadvantage of this type of elevator.

On the other hand, the hoist of an elevator with a machine room is usually smaller than an elevator without a machine room with the same load. However, their power saving ability is not as optimal as the structure of elevators without machine rooms, so it is necessary to consider carefully before deciding to choose the appropriate type of elevator.

Some disadvantages of elevators without machine rooms

Placing machinery inside an elevator shaft without a machine room often provides the benefit of compact size. However, this also makes it difficult to repair and maintain, especially when the engine has problems. Rescue plans during power outages are also more difficult than elevator structures with machine rooms.

The transmission ratio of a machine roomless elevator structure is usually 2:1, so the cable length is longer and the number of pulleys is also greater. This leads to increased maintenance and servicing costs due to the more complex servicing process.

Although machine roomless elevator prices may be higher than machine room elevators, their lifespan is often lower than other types of elevators.

When the elevator operates, noise is often created due to the steel connection, this is a notable difference compared to elevators with machine rooms.

The heat emitted from elevators without machine rooms can be quite large, and at the same time, their heat resistance is also relatively poor. Therefore, it is necessary to ensure that the outside temperature is not too high to avoid "loss of magnetism", which reduces the capacity and load-carrying capacity of the elevator compared to other types.

Should I choose an elevator without a machine room or one with a machine room?

When faced with the decision to choose the right elevator for your family, assessing your specific needs and intended use is extremely important. To help you make the right decision, here is some advice from Sankyo:

If your budget is limited, choosing an elevator with a machine room is a smart choice to save money. Although it may be limited in saving space, elevators with machine rooms still ensure basic features and convenience for families.

If you have ample finances, a machine room-less elevator will be the ideal choice. Not only does it save installation space, machine room-less elevators also bring comfort and modernity to the home. With advanced features, this is a valuable investment for your living space.

In cases where the installation space is limited in height, prioritizing the choice of elevators without machine rooms will help optimize the area. This not only brings efficiency in terms of space use but also ensures aesthetics and utility for the house.
