8.6.2 Mechanical Brake

8.6.2.1 Overview

The OneGearDrive Standard is available with a 180 V DC brake option. This mechanical brake option is intended for
emergency stop and park brake duty. Normal braking of a load is still controlled by the adjustable frequency drive dynamic
brake.
Spring-loaded brakes are safety brakes that continue to work in the event of power failure or usual wear. Since other
components could also fail, take suitable safety precautions to avoid any injury to persons or damage to objects caused by
operation without a brake.
WARNING
Danger of fatal injury if the hoist falls.
Severe or fatal injuries.
•
Do not use the brake in vertical lifting and hoisting applications.
