Tyre pressure of pneumatic tyres

Maximum tyre pressure is printed on the tyres
on each side.
Full tyre pressure – steering wheel
Standard:
2.5 - 3.5 bar = 36 - 50 psi
Full tyre pressure – drive wheel
Standard:
3.0 - 4.0 bar = 44 - 58 psi
Ultra-light running tyres:
6 bar = 87 psi
High pressure:
8 bar = 116 psi

Maximum range

The maximum range depends to a large extent
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 un-
der 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.
The maximum range is greatly reduced by:
32
– frequent driving upwards on ramps,
– insufficient charging condition of the drive
batteries,
– low ambient temperature,
– frequent starts and stops (e. g. in shopping
malls),
– aged, sulphated drive batteries,
– frequently necessary steering manoeuvres,
– reduced driving speed (especially at walk-
ing speed).
In practical use, the maximum range under
'normal conditions' is then reduced to approx.
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!

Applied norms

The electronic travelling wheelchair complies
with the norm:
– EN 12184: 2014
– ISO 7176-8: 2014
The models are allocated to application class A
according to the norm EN 12184.
The applied parts and components we use
are in compliance to EN 1021-2 for resistance
against inflammation.
