48. Which device is designed to automatically hold the load if power should fail to an electric winch?
Electromagnetic brakes automatically engage and hold the load when power fails, as they are spring-applied and electrically released; loss of power causes the brake to apply. Motor controllers only manage power, hand brakes require manual operation, and pneumatic brakes require system control, none of which provide automatic holding upon power failure.
