1. Step-support stair-climbing wheelchair
The step-support stair-climbing wheelchair has a history of nearly a hundred years in foreign countries. After continuous evolution and improvement, it is now the one with a relatively complicated transmission mechanism among all forms of stair-climbing wheelchairs.
Its principle is to imitate the climbing action of the human body, and it is alternately supported by two sets of supporting devices to realize the function of going up and down stairs. Step-supported stair-climbing wheelchairs have been widely used in foreign developed countries.
Widely used.
2. Star wheel stair climbing wheelchair
The stair-climbing mechanism of the star-wheel type stair-climbing wheelchair is composed of several small wheels evenly distributed on the "Y", "five-star" or "+"-shaped tie bars. Each small wheel can rotate around its own axis
The line rotates on its own, and can revolve around the central axis together with the tie rod. When walking on flat ground, each small wheel rotates on its own, and when climbing stairs, each small wheel revolves together, thereby realizing the climbing of stairs.
Function.
3. Crawler stair climbing wheelchair
The stair-climbing wheelchair with track-type mechanism adopts a more continuous walking mode than the star-wheel mechanism. When the track leaves the previous step or advances to the next step, there will be a weight loss.
The heart deviates and tilts forward and backward. Crawler-type stair climbing wheelchairs are not suitable for use in environments where the edge of the stairs is too smooth and the slope is greater than 30-35 degrees.
Out of the absolute need to ensure the safety of the disabled and the elderly going up and down the stairs, the safer rather than the cheaper stair climbing wheelchairs will still be given priority. Believe that with the step
Reflecting the high reliability of the stair-climbing wheelchair, it will gradually become the mainstream stair-climbing wheelchair in the future to serve more disabled and elderly groups.
