How To Choose The Right Access Ramp
1. What type of ramp do you need?
Depending on your application, you’ll need to select the best and safest ramp for your needs. There are three main types of ramps:
- Ramps for steps and stairs
- Ramps for door threshold or floor level changes
- Ramps for getting your mobility scooter or wheelchair in and out of vehicles
- Bespoke ramps for long flights of steps or difficult access points
2. What gradient is required?
Next you need to measure the height of the highest level you’re needing to reach. This will then enable you to decide which length of ramp will be suitable for your application. When measuring for your ramp, a general rule to follow is:
- Recommended gradient for self-propelled or independent wheelchair users is 1:12
- Recommended gradient for assisted wheelchair users over a short distance is 1:8
Let’s explain these two gradients. A 1:12 gradient means that the length is 12 times longer than the height of the step. A 1:8 gradient means that the length is 8 times longer than the height of the step and so on.
3. What length ramp is required?
We have listed below the relative ramp lengths for various step heights and gradients.
|Step Height||Length at 1:6||Length at 1:8||Length at 1:12|
|10cm (4ins)||60cm (2ft)||80cm (2ft 8″)||120cm (4ft)|
|15cm (6ins)||90cm (3ft)||90cm (3ft)||180cm (6ft)|
|20cm (8ins)||120cm (4ft)||160cm (5ft 4″)||240cm (8ft)|
|25cm (10ins)||150cm (5ft)||200cm (6ft 8″)||300cm (10ft)|
|30cm (1ft)||180cm (6ft)||240cm (8ft)||360cm (12ft)|
|45cm (1ft 6″)||270cm (9ft)||360cm (12ft)||540cm (18ft)|
|60cm (2ft)||360cm (12ft)||480cm (16ft)||720cm (24ft)|
