Build a telescopic ramp for a wheelchair

Wheelchair users are faced with insoluble problems when differences in level have to be overcome. A telescopic ramp can help up to a certain height. The wheelchair and driver must be able to be moved safely. Read about the aspects to be considered.

Wheelchair users are dependent on help.

What you need:

  • A square combination inside / outside
  • Checker plate
  • Screws, retractable
  • welding machine
  • drilling machine

How the telescopic ramp works

  • Obtain a square material that is almost completely closed, it only has to be slotted on one side. To do this, you need a second square that can be pushed into the former. If necessary, a pipe that does not have too much play in the square will do.
  • The load-bearing capacity of both parts of a telescopic ramp must be so great that they can safely bear the weight of the wheelchair and driver when they are only 1/3 put together. Both pipe systems each carry a platform that can be pushed over one another, thus making the telescopic effect possible.

The wheelchair determines the dimensions

  • The higher the ramp has to reach, the longer it should be so that the slope is not too steep. You can set the width to measure for a wheelchair (weight!), Or you can make the two lanes separately so that they can be used universally.
  • A stable, corrugated aluminum sheet can serve as a platform, but the width of the lane should not be more than 30cm. To prevent the ramp (s) from slipping off, they provide the upper support with a claw that is held securely in the vehicle floor or on the bumper.

How to assemble the telescopic ramp 

  • The two stronger support parts must be connected to the platform at the bottom. The slots point inwards. Place the screws so that they either face outwards or weld them on the outside. They must not obstruct the insertion of the thinner parts.

  • In general, each part of the telescopic ramp is about half the extension in length. Between the upper, stronger part and the lower part, a small step is formed due to the design, but this is not a serious obstacle. When pushed together, the levels are close together.
  • Assemble the weaker part, which is pushed into the stronger one, so that the platform engages in the two slots of the strong 4-edge. The distance between the insertion tubes must then be exactly large enough that they can be pushed easily.
  • If there are problems with the connection, you can weld webs to the thin insertion tubes, to which the platform is then screwed. Use a stop to ensure that the two parts cannot be extended more than 2/3 of their length.
