7.4. Driving on slopes or ramps
With all settings in the neutral position
(see 6.1), slopes/ramps of ≤6˚ (10.5%) are
deemed to be part of the standard user
environment for the FWD without stability
being affected (figure 33). For the RWD
and MWD the applicable gradient is ≤10˚
(17.6%).
Slopes or ramps outside the standard
user environment
Driving on slopes/ramps that are steeper
than the maximum safe slope may lead
to safety risks in terms of stability. Driving
on such slopes/ramps requires the user to
practise extreme caution and full control.
Always drive carefully and never experiment! Follow the instructions given under
warnings!
The stability and performance of the wheelchair depend on many variables.
Wheelchairs are adapted to individual users. For this reason these variables will be
different from one wheelchair to another. You should therefore ensure that your
dealer provides you with sufficient information about how to use the wheelchair
and that the dealer informs you whether the specific adjustments or adaptations
for your situation will affect the handling of the wheelchair.
Warning
• Always drive up and down slopes/ramps slowly, concentrating on what you are
doing.
• Avoid any sudden, jolting movements.
• Avoid making an emergency stop on a slope/ramp.
•
The braking distance on a slope can be considerably greater than on a flat
surface.
• When on slopes/ramp, try to avoid changing direction as much as possible.
• Do not turn on a slope.
• Drive on slopes/ramps only when all adjustments (lift, tilt, recline) are in the
neutral position.
• Never drive up or down a slope/ramp backwards.
• Do not drive on slopes/ramp with loose gravel or a sandy surface, as one of the
drive wheels may slip or spin.
• Driving up or down a slope for long periods of time may result in the motor
overheating.
• We always recommend an anti-tip device for driving down slopes in a FWD
wheelchair.
• If you notice that your speed is being greatly reduced when driving up a slope,
select a route that is less steep.
• Prevent the wheelchair from reaching high speeds when driving down slopes.
