Nowadays, consumers are increasingly opting for boxless elevator traction devices, particularly in passenger elevators and home elevators. Although the gearless elevator traction machine has a greater initial investment cost than the geared type, the excellent advantages and long-term usage value of this equipment provide numerous benefits to consumers:
- Machine size is compact, making it ideal for a wide range of elevators, both with and without a machine room. Save space while maintaining the building's beauty.
- It operates silently and requires no maintenance thanks to permanent magnet technology. As a result, the equipment has a longer life than the gearbox (need to change the oil for regular maintenance).
- When compared to tractors with gearboxes, the energy savings are more than 60%, and 80% compared to hydraulic ladders. This benefit is especially valuable when the cost of power in Vietnam rises, especially during peak summer months when demand for electricity rises dramatically.
- Environmental protection is achieved through reducing CO2 emissions.

However, there are many distinct kinds of gearless elevator traction machines available from various manufacturers all over the world.
Here are some characteristics to assist users compare around 6 types of elevator traction machines that are currently prevalent in the Vietnamese elevator industry.

General assessment:
In general, European elevator tractors are constructed with very high protection requirements (IP21) and are water and moisture resistant, which is considerably superior to tractors from Asia such as Fuji (Korea), Sharp (India), or Torin (China), which only meet IP40-IP41 standards. However, because the cost of elevator tractors in Asia is significantly lower than that of tractors in Europe, they can meet the majority of the demands of regular customers.
The aforementioned elevator traction machines are virtually identical in terms of specifications in the case of a 450kg elevator moving at 1m/s. The ZIEHL-ABEGG elevator tractor, however, is a notable feature of the German tractor range. The ZIEHL-ABEGG tractor from Germany is built with a high rpm (168rpm) and a low noise level of 50dB. Furthermore, ZIEHL-ABEGG tractors can reply 240 times per hour, which is significantly higher than the rest of the elevator tractors, which can only answer 180 times per hour. The ZIEHL-ABEGG tractor series, in particular, performs well in hot and humid conditions, resists oxidation when working close or at sea, and is preferred by many elevators for ship elevators.
As a result, the German tractor from ZIEHL-ABEGG is now the best choice for clients that have a high demand for usage, extended equipment life, and differentiation.
In conclusion, the elevator traction machine is one of the most significant and valuable elevator components. The choice of an elevator traction machine must always fulfill technical criteria, assure safety, and have a clear origin. Consumers may then choose the best choice for themselves based on their requirements, interests, and budget.
