Portable ramps can be differentiated into 3 subgroups:
ramps These bridge small door thresholds.
ramps These bridge several steps. The ramp rests on the top step or on intermediate steps.
ramps These consist of two separate lanes and can be rigid or telescopic in length. They are used to negotiate steps or to cross over into cars. The distance between the lanes can be determined individually.
Stationary ramps are permanently fixed and can be folded according to the model. The height to be overcome is decisive for the length of the ramp. The gradient should not be higher than 6 % to allow independent overcoming. A ramp should end on a platform and, in the case of long stretches, have intermediate platforms for rest 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 a railing and portable ramps should be positioned near railings. Many models have edge protection to prevent them from rolling off to the side.
Only mobile ramps are an aid in the sense of the statutory health insurance and can be found in the GKV aids directory under item number 22.50.01.0XXX.
