USCG Exam PracticeDeck machinery and ground tackle
On a cargo winch or deck crane, what must the brake be capable of doing if power or control is lost?
- ✓ Automatically holding the rated loadCorrect
- B. Slowly lowering the load to the deck at a controlled rate
- C. Triggering the overload cut-out before the load is released
- D. Engaging the limit switch to stop all hoist motion
Why A is correct
Per NAVEDTRA 14343 §9-4, cargo winch brakes must hold the rated load automatically when power or control is lost. Controlled lowering, overload cut-outs, and limit switches are separate safety features and do not substitute for this brake requirement.
