Which device stops the motor if chain slackens?

Explanation:
When chain tension drops, a dedicated safety device detects the slack and immediately cuts power to stop the drive. This Slack-Chain Device is built to sense slack in the drive chain and trigger a stop signal to the motor, preventing chain slip, jump, or derailment. The winding drum merely stores or pays out the chain and isn’t a slack detector; control switches handle general on/off control and safety interlocks but aren’t activated specifically by chain slack; the code data plate is just informational labeling. So, the mechanism that stops the motor when the chain slackens is the Slack-Chain Device.
