Portable ramps can be differentiated into 3 subgroups:
- Threshold ramps
These bridge small door thresholds.
- Step ramps
These bridge several steps. The ramp rests on the top step or on intermediate steps.
- Rail ramps
These consist of two separate lanes and can be rigid or telescopic in length. They are used to negotiate steps or to transfer to a car. The distance between the lanes can be determined individually.
Stationary ramps are permanently fixed and can be folded, depending on the model. The height to be overcome is decisive for the length of the ramp. The slope should not be higher than 6 % to allow independent overcoming. A ramp should end on a platform and, in the case of long distances, should have intermediate platforms for rest breaks.
To allow for safe use of ramps, attention should be paid to the max. load when purchasing. In addition, stationary ramps should have railings and portable ramps should be positioned near railings. To prevent rolling sideways, many models have edge protection.
Only mobile ramps are assistive products as defined by the Statuatory Health Insurance's Medical Technical aids register under item number 22.50.01.0XXX.
