🔍 Key Concepts

• Pedestal crane motions: luffing (boom up/down), slewing (house rotation), hoisting (load up/down) • Limit switches: safety devices that stop motion before mechanical or structural limits are exceeded • Difference between rate limits (speed of motion) vs travel limits (how far a motion can go)

💭 Think About

• Which crane movement, if allowed to rotate too far, could cause the crane to hit structural stops, crush equipment, or foul with ship structures? • Do limit switches usually control how FAST a motion occurs, or do they primarily stop motion at the END of its safe range? • Among the options, which one clearly refers to how FAR the crane can rotate in azimuth, rather than how quickly it moves or how much power is applied?

✅ Before You Answer

• Identify which answer choices refer to speed/rate versus which refer to distance/angle of movement • Recall that limit switches are typically installed at the ends of travel (end stops), not to control normal operating speed • Confirm in your mind which function describes the crane’s rotational range around its pedestal rather than its speed or power
