Question 356General Subjects - QMED

The correct answer is C) engaged by spring action and only released by hydraulic pressure. When the hydraulic control lever for a deck winch is placed in the neutral or off position, the spring-set brake on the fluid motor drive shaft is engaged by spring action. This is to ensure that the winch drum is locked in place and cannot rotate freely, which could pose a safety hazard. The hydraulic pressure is required to release the spring-set brake and allow the winch to operate. The other options are incorrect because A) the brake is not opened hydraulically, B) the brake is not engaged by both spring action and hydraulic pressure, and D) the brake is not released by spring action and does not hydraulically lock the winch when the drum stops rotating.
