15.1. PRE-ADJUSTMENT OF THE BRAKE
The winches are normally supplied with the brake that requires
some adjustment based on the characteriscs of the system. The
braking distance depends on the compression of the brake’s springs;
the springs need to be adjusted to obtain the braking torque of the
braking system that is suitable for the system, and in compliance
with
EN81.20-50 (See chart).
If an addional adjustment is required, follow the instrucons
reported in the following chapter.

15.2. BRAKE ADJUSTMENT
The brake has two separate magnets so that the shoes operate
independently of each other.
Usually the brake shoes must open with the shortest stroke
possible, but without showing any fricon on the brake’s drum
under the normal winch working condion.
Check periodically the status of wearing of the brake’s shoes’
fricon material. In case of wear, proceed with the adjustment
operaons in compliance with what’s provided in the following
chapters.
During each adjustment intervenon, make sure that between the
opened brake’s shoe (winch free to rotate) there’s a space equal to
0.1-0.15 mm in the lining’s lower part, by verifying with a calibrated
spacer.
15.2.1. STROKE ADJUSTMENT
- Loosen the locknuts (2) on both the brake shoes and unscrew
the adjusng screw (1) leaving a clearance of 4-5 mm between
the screw and the electromagnet pin (5),
- turn the brake opening lever (6) to the “open” posion,
- ghten the adjusng screws (1) by hand unl they are ush with
the electromagnet pin (5),
- turn the brake opening lever (6) to the “closed” posion and ghten the adjusng screw half a
turn (equal to about 0.1-0.15 mm in the lining’s lower part) against the electromagnet pin,
- ghten the locknuts (2).
15.2.2. CHECKING THE ADJUSTMENT
Move the cab up and down and listen to the noise level. The stroke is correctly adjusted if the brake
lining does not touch the brake drum while the li is moving and no noise is heard when braking.
