7.3.1 Setting / checking braking deceleration
Basic setting of the brakes
The braking force (contact pressure of the brake block) is executed uniformly
and specifically for each machine 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 7.3.1
Machine Initial spring tension distance
DAF380 32 mm (corresponds to approx. 13 revolutions)
Table 7.3.1
If this brake adjustment is changed, the configuration complying with
EN81/A3 is invalid and must be checked!
However, if it is necessary to adjust the brake later, proceed as follows.
To set the initial tension distance:
tighten the setting nut (Figs. 7.3 and 2.1) by hand as far as possible.
Make sure that the compression springs are seated centrally in the brake
shoe; the compression springs must not contact the side of the brake shoe.
Then set the initial tension distance according to the table / illustration
(corresponding to the revolutions of the setting nuts as a guide value) and
lock the setting nut (100 - 200 Nm).
DAF3801xx / braking torque: 2400 Nm
(95)
16 mm (recessed in housing)
111 mm = length with initial tension
143 mm = free length
If the maximum value is exceeded, this can impair the brake function.
