The concept of barrier-free slope
In fact, as long as you go up and down the slope, there is a slope problem, but today we will only talk about the concept of barrier-free slope. For pushing a wheelchair up and down a barrier-free slope,
Other automobiles, motorcycles, pushing goods or other strange applications will be discussed in the future when we have the opportunity.
When the height remains unchanged, the longer the barrier-free ramp, the gentler the slope, and the shorter the barrier-free ramp, the steeper the slope. This is basic common sense,
A difference of 1 degree in barrier-free slope will be noticeable to the driver, but a slope of 1 degree cannot be distinguished by the naked eye.
Many people often say that the visual measurement is 45 degrees, but I dare say that 95% of the calculated results are less than 45 degrees.
45 degrees is a very steep slope. You have to keep your center of gravity forward even when walking. It is not surprising if you accidentally slip and fall, let alone push a wheelchair up and down.
There is a demonstration of 37.3 barrier-free slope in the video. It is definitely not just a random slope.
I often encounter some very exaggerated requirements. If the height is 40 cm, I need to buy a 50 cm slope board!
This simply means that the board is erected at the same height. How can the concept of almost two parallel lines become a slope?! The barrier-free slope is too steep not only for wheelchairs to push it up, but also more dangerous when coming down. It is better to find two people to lift it up directly to save money and effort. and safe Continue reading Ramp Primary School CHAP 39 The concept of barrier-free slope
