OPERATING MANUAL TW63 PRODUCT DESCRIPTION
ThyssenKrupp Aufzugswerke GmbH
Depending on the version, the drive comes from a three-phase motor
standing vertically on the gear or flange-connected horizontally on the gear to
the worm shaft, via worm wheel, traction sheave shaft to the traction sheave.
Brake:
The dual circuit shoe brake is spring actuated. Two independently acting
brake shoes press the brake lining onto the brake disc with spring force
preset on the system.
The braking force is configured in such a way that one of the brake blocks is
sufficient to bring an elevator car loaded with full weight to a standstill.
The brake is released by electrically operated magnetic clamps.
In the case of manual operation, the enclosed brake release lever must be
applied to the cast-on recesses of the ends of the brake shoes. Pressing in
the direction of the machine (see Fig. 2.2.1 in the direction of the arrow)
presses the brake shoes apart, triggering the brake.
