Portable ramps can be differentiated into 3 subgroups:
- Threshold ramps
These bridge small door thresholds.
- Step ramps
These bridge several nebulizers. The ramp rests on the top nebulizer or on intermediate nebulizers.
- Rail ramps
These consist of two separate lanes and can be rigid or telescopic in length. They are used to negotiate nebulizers or to transfer to a car. The distance between the lanes can be individually determined.
Stationary ramps are permanently fixed and can be folded up, 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 enable independent negotiation. A ramp should end on a platform and, in the case of long stretches, have intermediate platforms for recovery breaks.
To ensure safe use of the ramps, the maximum load should be taken into account when purchasing them. In addition, stationary ramps should have railings and portable ramps should be positioned near railings. To prevent the ramp from rolling sideways, many models have edge protection.
Only mobile ramps are aids in the sense of the statutory health insurance and can be found in the GKV list of aids under the item number 22.50.01.0XXX.
