Electric cargo winches have an overload safety device which normally cuts the current to the winch motor __________.

🔍 Key Concepts

• Safe Working Load (SWL) of the fall versus rated capacity of the winch • Purpose of an overload safety device on electric cargo winches • Difference between breaking strength and safe working load of a line or fall

💭 Think About

• Ask yourself: Is the overload device designed to act at the point of failure, or to prevent reaching that point? • Consider which component is more likely to be protected first: the wire/rope (fall) or the winch machinery itself. • Think about how a conservative safety margin is usually applied in lifting gear: do we work at breaking strength, or well below it?

✅ Before You Answer

• Verify how safe working load (SWL) relates to breaking strength (what safety factor is typically implied). • Compare the meaning of rated capacity of the winch with the safe working load of the fall—are they always the same? • Check which wording describes an overload device that trips preventively rather than at or after an overload condition has fully developed.

Question 1 of 27070

Electric cargo winches have an overload safety device which normally cuts the current to the winch motor __________.

when the line pull reaches the breaking strength of the fall

before the safe working load of the fall is reached

after torque causes line pull to exceed the rated capacity of the winch

before the line pull reaches the rated capacity of the winch
