DisabledRamps.co.uk -
The UK's largest supplier of disabled access wheelchair ramps
For
independent users of manual wheel chairs: Max. gradient 1:7.
For manual wheelchairs pushed by a helper and for electric wheel chairs:
Max. gradient 1:5.
Example: To overcome a height difference of 200 mm and a maximum
gradient of 1:5 a ramp of 1000 mm long would be suitable (5 x 200 = 1000).
A
gradient of 1:12 is desirable where possible.
Where level access is not achievable,
ramps
enable wheelchair users and people with pushchairs to overcome level
changes.
-
Ramps should be accompanied by steps for ambulant disabled people
where the rise of the ramp is greater than 300mm and by alternative
means of access (a lift, for example) for wheelchair users if the
total rise is greater than 2m.
- Ramped approaches should be clearly signed if not readily
apparent.
- The permissible
gradient of a ramp is dependent on the length between level
landings (the ‘going of the flight’). However, it should be noted that
a route with a
gradient of 1:20 over a significant distance can still be a
potential barrier.
-
Ramps should be as shallow as possible. The maximum permissible
gradient is 1:12 (see Figures 1, 2 and 3), with the occasional
exception in the case of short, steeper
ramps
when refitting existing buildings.
