6.6.4 The correct way to overcome obstacles

Right
Ascending
1. Approach the obstacle or the curb slowly, head-on and at a
right angle.
2. Depending on the wheel drive type, stop in one of the following
positions:
a. In the case of centrally driven mobility devices: 5 - 10 cm
before the obstacle.
b. For all other drives: approx. 30 - 50 cm in front of the
obstacle.
3. Check the position of the front wheels. They must be in driving
direction and at right angles to the obstacle.
4. Approach slowly and keep at a consistent speed until the rear
wheels have also passed over the obstacle.
Descending
The approach to descend an obstacle is the same as to ascend it with
the difference that you need not to stop before descending.
1. Descend the obstacle with medium speed.
When descending an obstacle too slowly it could happen
that the antitippers get stuck and lift the drive wheels
off the ground. A driving of the mobility device is then
no longer possible.

Ascending obstacles with a curb climber
1. Approach the obstacle or the curb slowly, head-on and at a
right angle.
2. Stop in the following position: 30 – 50 cm in front of the obstacle.
3. Check the position of the front wheels. They must be in driving
direction and at right angles to the obstacle.
4. Approach with full speed until the curb climber makes contact
with the obstacle. The impetus will lift both front wheels over
the obstacle.
5. Keep at a consistent speed until the rear wheels have also passed
over the obstacle.
