🔍 Key Concepts

• Design and safety features of electric cargo winches • What happens to electromagnets and motor torque when electrical power is lost • How mechanical devices like pawls, brakes, and gears behave without power

💭 Think About

• Think about which system parts rely on electric current to work and which are purely mechanical. • If all electric power disappears instantly, which option describes a behavior that could still happen without any electricity at all? • Consider what a well-designed cargo winch must do in a blackout to prevent a dangerous runaway load.

✅ Before You Answer

• Identify which options describe devices that need electric power to remain engaged. • Decide which options describe an action that requires active human input at the exact moment of power loss. • Ask which mechanism would be considered a fail-safe design for holding a suspended load during a total power failure.

If an electric cargo winch is being used to lift a draft of cargo and the engine room loses all power, which will occur?

An electromagnetic brake will hold the load where it is suspended.

The load will fall rapidly to the deck unless the foot brake is engaged.

A pawl, forced by a spring mechanism, will engage the teeth of the bull gear and hold the load.

The load will slowly lower to the deck under control of the drag of the winch motor.
