PERIODICAL INSPECTIONS
Every brake in operation should be subjected to inspections. The operating period after which
inspections are required depends on intensity of operation and is given in the instructions of the
final equipment, e.g. lifting equipment. During inspections (after removing the brake casing (7)),
perform the following:
Remove accumulated dirt from inside the brake,
•
Check the degree of wear of friction linings and replace them with new ones if necessary,
•
Check the size of the air gap and if ascertained that it has attained the maximum value or is
•
approaching the limits of the maximum value, adjust the brake air gap,
Perform a few trials and check the effectiveness of braking. If reduced effectiveness with
•
respect to the original state is ascertained, dismantle the brake to check the state of brake
disk friction linings, the state of friction surfaces of the armature and the motor bearing shield
or brake mounting disk depending on the brake configuration.
