Q

Pedestal cranes have limit switches to restrict the movement of which function?

🔍 Key Concepts

• Limit switches on pedestal cranes and what they are designed to prevent • Difference between slewing (rotating the crane), luffing (raising/lowering the boom), and structural limits like a turntable stop • Why crane manufacturers add electrical/automatic cut‑outs to protect against over‑travel and overload

💭 Think About

• For each option, ask: does this motion risk the boom or wire going too high/too low, or overstressing the structure if not automatically cut off? • Think about which motion is most likely to cause the boom angle to become unsafe if it continues unchecked. • Consider which items are usually protected by mechanical stops or physical structure versus those that need electrical limit switches for safe travel limits.

✅ Before You Answer

• Identify which function directly changes the boom angle and load radius during operation. • Decide which motions normally have mechanical rotation stops instead of, or in addition to, limit switches. • Before choosing, be sure you can clearly define: slew, luff, and turntable on a pedestal crane.
