What does the down limit switch do?

• A. Prevents overheating of the motor
• B. Controls motor speed
• C. Automatically stop the hoist motor when the cable has been paid out to the preset limit
• D. Stops the motor when the cable is wound in

Answer: (C)

The down limit switch is a safety device that stops the hoist once the cable has been paid out to its preset lower travel limit. When activated, it interrupts the hoist motor so the load cannot descend any further, protecting the cable, drum, and load from over-travel or damage. It isn’t about preventing motor overheating or controlling speed—that’s handled by other systems. The up limit switch does the opposite function, stopping the motor when the cable is wound in to prevent over-winding.
