Crawler stair machine (press upleft), as its name suggests, is similar to the tracks of a tank, with a more flat-lying design. This stair machine is suitable for wider and less inclined stairs. It is simple to operate and is called fool-proof operation. It is easy to get started. Suitable for some relatively spacious places, existing customers include cultural centers, city halls, Queen Elizabeth Hospital, etc.

On the other hand, the pole stair machine (press theright) design is more upright and slender, suitable for narrow stair spaces, such as traditional Chinese tenement buildings. Although it is difficult to drive, it can adapt to the needs of narrow spaces and is very suitable for special buildings such as tenement buildings. Existing clients include the Tuen Mun Hospital non-emergency service team and village tenement houses.
