11.2 Permissible friction lining wear and replacement of the friction blocks
Life-threatening danger!
Friction blocks may only be changed when the system or the work machine is
stationary!
Important!
When new, the friction lining has a thickness of 12.5 mm. After 4.5 mm of wear
or a residual lining thickness of 8 mm, the friction blocks must always be
replaced in pairs.
Only original RINGSPANN friction blocks may be used.
Important!
Before replacing the friction blocks, make sure that the mass held by the brake is
secured against movement, as the brake must be released (opened) to change
the friction blocks.
Important!
Make sure that no electrical voltage is applied to the brake caliper.
Turn the screw (6) into the thread of the brake lever and the two set screws (3) back into the lever
so far that you can easily change the friction blocks.
After changing the friction block, you must readjust the braking torque as described in item 8.4.
Finally, the new friction linings must be applied by braking briefly several times so that the brake
can achieve the required braking torque (see chapter 9).
11.3 Emergency release
Open the brake caliper manually by loosening the lock nut and screwing the screw (6) into the
lever by turning it clockwise. Turn the screw into the lever until you can move the friction blocks
on the brake disc.
