Check brake wear

Check brake wear depending on the year of manufacture of your chain hoist:
● When the max. brake displacement is reached (see  Tab. 64, Page 88), the brake must be replaced immedi‐
ately.
● For brake displacement up to 0,5 mm, the brake can still be used until the next maintenance is due.
As of year of manufacture 04/2009
Fig. 62
Since 04/2009 – depending on the size of model – brakes have been gradually equipped with a plug inside the
brake housing to enable brake wear to be measured without the need to remove the brake. Brake wear is meas‐
ured by the air gap.
Disconnect the chain hoist from the power supply (mains connection switch) and secure it against switching on
again.
● Open the electric equipment cover.
● Unscrew brake plug screw (1) from the brake.
● Check brake wear with feeler gauge (2) (see  Tab. 64, Page 88).
