10.2.1 Hoist brake
10.2.1.1 Functional description
Electromagnetically opened spring loaded D.C. disk brakes require little maintenance.
The brake torque is generated by spring force. The pressure springs of the brake press the brake disc, which is
connected to the motor shaft in a form-locking fashion, to the motor flange via the axially moving anchor plate. At this
point the brake torque is created.
When applying direct current to the field winding of the brake magnet it exerts a magnetic force. This magnetic force
attracts the anchor plate to the brake magnet. The brake opens.
As an option the brake can also be opened manually, mechanically. When actuating the manual opening lever the
anchor plate leans up against the brake magnet. The brake opens.
