7.6 Setting / checking braking deceleration
Basic setting of the brakes
The braking force (contact pressure of the brake shoe) is executed machine-
specifically and uniformly by means of the initial tension of the brake springs
at the two brake shoes. On delivery, the brake is set ex works as standard
depending on type, see Table 7.6.1
Machine Initial spring tension distance
DAB530 42 mm (corresponds to approx. 12 revolutions)
Table 7.6.1
If this brake adjustment is changed, the configuration complying with
EN81/A3 is invalid and must be checked!
However, if it is necessary to set the brake subsequently, proceed as follows.
To set the initial tension distance:
tighten the setting nut (Fig. 7.3) by hand as far as possible.
Make sure that the compression spring is seated centrally in the brake shoe;
the compression spring must not touch the side of the brake shoe. Then set
the initial tension distance in accordance with the table/illustration
(corresponding to the turns of the setting nut as a reference value) and lock
the setting nut (100-200 m)
DAB530 / braking torque: 7500 Nm
162 mm = length with initial tension
204 mm = free length
If the specified number of revolutions is exceeded, this can impair the
brake function.
