Frequently Asked Questions
Q: How does the overload protection work?
A: The system uses a load cell to continuously monitor the load weight. If the load exceeds the preset threshold (typically 10-20% above rated capacity), the system automatically stops the hoist and activates an alarm.
Q: Can the overload threshold be adjusted?
A: Yes, the threshold is adjustable. We recommend setting it at the lowest practical level for your application to ensure maximum safety.
Q: Does the overload system require calibration?
A: Yes, we recommend annual calibration verification to ensure accuracy. Our service team provides calibration and recertification services.
