DANGER
Damaged tyres or wheels may be the cause of a serious accident.
While checking pressure pay attention to technical condition of wheels and tyres. Look
carefully at tyre sides and check the condition of tread. In case of mechanical damage
consult the nearest tyre service and check whether the tyre defect requires tyre replacement.
Wheels should be inspected with regard to distortion, breaking of material, breaking of welds,
corrosion, especially in the area of welds and contact with tyre.
INSPECT
•
Every month of use.
•
Every week during intensive work.
5.2.6 CHECK THICKNESS OF BRAKE SHOE LININGS
During use of trailer, friction lining of brake drums is subject to wear. In such a case, the
complete brake shoes should be replaced with new ones. Excessive wear of brake shoes is
the condition in which the thickness of linings which are glued or riveted to steel structures of
brake shoes is smaller than the minimum value. This condition is indicated by extended
cylinder piston stroke. Check technical condition of brake shoe linings through inspection
openings (3) – figure (5.6).
TIP
Minimum thickness of brake shoe linings is 2 mm.
