Humping Ramp / Wheelchairs, ramps, sidewalks

It is not easy for disabled people to 'go upstairs' even using a ramp. They need to sprint all the way up to the end of the ramp or the rest area without a stop. Otherwise they’ll roll backward.
Ramp of hump is a wheelchair access combined the concept of stairs and ramp. Thanks to the special designed humps on the ramp, a wheelchair can climb to the top “step by step” and can stop anywhere on the ramp.

To build such a ramp is simple and practical. Factories will manufacture the shaped tiles and the rest work is just tiling them on a ramp.
