3.6.1 wheel lock
3.6 Assembly group brake
(1 next page)
Each wheelchair is equipped with two wheel locks. They consist of brake pressure
bolts
(A)
, brake lever
(B)
(possibly also with extension), adjusting screws
(C)
and if necessary the
bowden cable.
Wheel locks is used exclusively to lock the wheels in a resting position.
They are not designed to decelerate the wheelchair from the ride.
The correct operation of the brakes can be affected by:
• too low tire pressure,
• Wet, snow, mud, ice, dirt, etc.,
•
crazy profile,
• worn brake pin,
• loosened brake bolt bolts,
• dirty drum brake,
• defective Bowden cable (with drum, attendant or one-hand brake),
• too much distance between brake pressure pin and tire.
Check all bolted connections of the brakes for their tightness at regular intervals.
After all changes to the rear wheels, adjust the brake. On a ramp with a gradient of 12%
(= 7 °), the rear wheels of the wheelchair must not slippage at maximum load with the wheel
lock on.
When the brake is open, the maximum distance between the brake pressure pin and tires is de-
termined as follows:
Standard KHB
21 mm
Pull-to-lock brake
11 mm
KHB with backstop approx.
10 mm
cable control brake
6 mm
