As it pertains to the automatic hoist winch brake of an electro-hydraulic cargo- handling pedestal-type deck crane, what statement is true?
AI Explanation
The correct answer is B.
The brake in an electro-hydraulic cargo-handling pedestal-type deck crane is spring set and hydraulically released. This means that the brake is normally engaged, and hydraulic pressure is required to release it. When the hoist pump is brought to zero stroke or there is a loss of servo power hydraulic pressure, the brake automatically sets to prevent the load from falling.
The other options are incorrect because they describe the opposite brake configuration (hydraulically set and spring released), or the incorrect automatic brake behavior (automatically releasing instead of setting) when the hoist pump or hydraulic pressure is lost.
