Abstract
A powered ascender has a motor, a brake assembly, and a gearbox. The gearbox is mechanically coupled between the motor and the brake assembly. The brake assembly applies a maximum braking force while the motor is not rotating. The brake assembly applies a lesser braking force in response to the motor rotating in a reverse direction.
