Technical Specifications

Backup Brake System

• Operation:

• Drum rotation reaches 1.25× normal speed.

• Centrifugal force engages mechanical stop.

1. Normally inactive during regular use.

2. Activates automatically if primary brake fails:

3. Safety switch prevents lowering operation.

• Emergency Lowering Procedure:

• Use "UP" command to reset brake.

• Repeat as needed for controlled descent.
