TECHNICAL DATA
Maximum range
The maximum range depends to a large ex-
tent on the following factors:
–
battery condition,
–
weight of the driver,
–
driving speed,
–
driving style,
–
road surface condition,
–
driving conditions,
–
ambient temperature.
The nominal values given by us are realistic
under the following conditions:
–
Ambient temperature of 27 °C.
–
100 % rated drive battery capacity as
per the DIN standard.
–
new condition of the drive batteries
with more than 5 charging cycles.
–
Nominal load of 100 kg.
–
Without repeated acceleration.
–
Level, firm driving surface.
Short form of wheelchair dimensions:
SH = Seat height
SW = Seat width
SD = Seat depth
BH = Back support height
Calculation of the max. user weight:
The maximum total load is calculated on
the basis of the unloaded weight of the
wheelchair and the maximum passenger
weight.
Additional weight due to subsequent addi-
tions or luggage reduce the maximum per-
missible passenger weight.
Example:
A driver wishes to take luggage with a
weight of 5 kg. Thus, the maximum user
weight is reduced by 5 kg.
The maximum range is greatly reduced by:
–
frequent uphill driving,
–
insufficient charging condition of the
drive batteries,
–
low ambient temperature (e.g. in win-
ter)
–
frequent acceleration and braking (e.g.
in city traffic)
–
aged, sulphated drive batteries,
–
frequently necessary steering manoeu-
vres,
–
reduced driving speed (especially at
walking speed).
In practical use, the maximum range under
'normal conditions' is then reduced to ap-
prox. 80 – 40 % of the nominal value.
Hill climbing ability
Gradients in excess of the permitted values
(e.g. ramps) should for safety reasons only
be driven when the wheelchair is empty!
