Question 535 Deck General
70% to passPedestal cranes have limit switches to restrict the movement of which function?
The correct answer is C) Slew travel limits. Pedestal cranes on ships and offshore platforms are equipped with limit switches to restrict the slew (rotation) travel of the crane. These limit switches prevent the crane from rotating beyond a certain range, which is important for safety to avoid damage to the crane, ship, or surrounding structures. The other options are not directly related to the primary function of the limit switches on a pedestal crane. Option A (Slew rate limits) refers to limiting the speed of rotation, which is a separate function. Option B (Luff rate limits) relates to limiting the speed of the boom's vertical movement, not the rotation. Option D (Swivel power limits) is not a common function of limit switches on pedestal cranes.
