Which device is designed to automatically hold the load if power should fail to an electric winch?
AI Explanation
The correct answer is A) Electromagnetic brake.
An electromagnetic brake is designed to automatically hold the load if power should fail to an electric winch. This is a safety feature that ensures the load is securely held in place even in the event of a power failure, preventing the load from dropping unexpectedly.
The other options are not designed for this specific purpose. A hand brake requires manual operation, a pneumatic brake relies on air pressure, and a motor controller manages the winch's operation but does not automatically hold the load in a power failure.
