Disconnect the chain hoist from the power supply (mains connection switch) and secure it against switching on
again.
● Open the electric equipment cover.
● Disconnect brake connector.
● Dismantle brake.
Measure brake wear with calliper gauge as follows:
● Measure the distance from the back of the brake to the brake disc with a depth gauge or calliper gauge when
the brake is not actuated.
● Measure the distance from the back of the brake to the brake disc with a depth gauge or calliper gauge when
the brake is actuated; to do this, press the brake disc against the springs until it stops.
● Use both measured values to calculate the difference; this difference is the brake displacement.
Assembly and maintenance
Fig. 64
When the brake is installed, make sure that the area of the V sealing ring (1) on the brake base is lightly
greased. Ensure that no grease penetrates inside the brake. The continuous sealing lip must be in full contact
with the back of the brake.
In the course of the annual inspection, V sealing ring (1) of the brake must be re-greased with anti-friction bearing
grease without any solid lubricant.
