For adjustment of brakes with torque applied, see below.
Brake adjustment without braking torque
1. Remove locking devices on adjustment screws.
2. Stretch the bands with the adjustment screws when the pressure is applied
to the brake cylinder. Drain the brake cylinder, check the measurement FK and
adjust to 107 mm (4.21 in). The scale indicators, sign 2, should then show green.
3. Replace the locking devices on the adjustment screws.
Adjustment of brakes with braking torque
Adjustment-check of bra kes with braking torque is only to be performed when the
bra kes cannot be relieved of braking torque.
The value of the braking torque must be used when checking the adjustment. Read
from the diagram if adjustment is necessary.
See "Brake adjustment without braking torque" for the adjustment procedure.
Example: With BA-85, a line force F of 100 000 N and a line drum of radius r = 0.5
metres, the braking torque is Mb = 50 000 Nm. The brake is to be adjusted if the FK
measurement is less than 84 mm (3.31 in). Adjust FK to 98 mm (3.86 in).
